(VACCINATION PROVIDERS)
EMERGENCY USE AUTHORIZATION (EUA) OF
THE JANSSEN COVID-19 VACCINE TO PREVENT CORONAVIRUS
DISEASE 2019 (COVID-19)
WARNING: THROMBOSIS WITH THROMBOCYTOPENIA SYNDROME
See Full EUA Prescribing Information for complete warning.
The Janssen COVID-19 Vaccine can cause thrombosis with thrombocytopenia syndrome
(TTS) which may be life-threatening.
TTS may involve thrombosis at unusual locations for a thrombus (i.e., cerebral vein, visceral
artery or vein, extremity artery, central artery or vein) or in an extremity vein or pulmonary
artery.
Among reported cases of TTS following administration of the Janssen COVID-19 Vaccine,
symptoms began approximately one to two weeks after vaccination.
Instruct Janssen COVID-19 Vaccine recipients to seek immediate medical attention for
shortness of breath, chest pain, leg swelling, persistent abdominal pain, neurological
symptoms (including severe or persistent headaches or blurred vision), or petechiae beyond
the site of vaccination.
The clinical course of TTS following administration of the Janssen COVID-19 Vaccine
shares features with autoimmune heparin-induced thrombocytopenia. In individuals with
suspected TTS, the use of heparin may be harmful and alternative treatments may be
needed.
Do not administer the Janssen COVID-19 Vaccine to individuals with a history of thrombosis
with thrombocytopenia following the Janssen COVID-19 Vaccine or any other adenovirus-
vectored COVID-19 vaccine.
The U.S. Food and Drug Administration (FDA) has issued an Emergency Use Authorization
(EUA) to permit the emergency use of the unapproved product, the Janssen COVID-19 Vaccine,
for active immunization to prevent COVID-19 in individuals 18 years of age and older for whom
other FDA-authorized or approved COVID-19 vaccines are not accessible or clinically
appropriate, and in individuals 18 years of age and older who elect to receive the Janssen COVID-
19 Vaccine because they would otherwise not receive a COVID-19 vaccine.

the vaccine.
• Before withdrawing each dose of vaccine, carefully mix the contents of the multi-dose vial
by swirling gently in an upright position for 10 seconds. Do not shake.
• Each dose is 0.5 mL. Each vial contains five doses. Do not pool excess vaccine from multiple
vials.
• The Janssen COVID-19 Vaccine does not contain a preservative. Record the date and time
of first use on the Janssen COVID-19 Vaccine vial label. After the first dose has been
withdrawn, hold the vial between 2° to 8°C (36° to 46°F) for up to 6 hours or at room
temperature (maximally 25°C/77°F) for up to 2 hours. Discard if vaccine is not used within
these times.
Administration
Visually inspect each dose in the dosing syringe prior to administration. The Janssen COVID-19
Vaccine is a colorless to slightly yellow, clear to very opalescent suspension. During the visual
inspection,
• verify the final dosing volume of 0.5 mL.
• confirm there are no particulates and that no discoloration is observed.
• do not administer if vaccine is discolored or contains particulate matter.
Administer the Janssen COVID-19 Vaccine intramuscularly.
CONTRAINDICATIONS
Severe Allergic Reactions
Do not administer the Janssen COVID-19 Vaccine to individuals with a known history of a severe
allergic reaction (e.g., anaphylaxis) to any component of the Janssen COVID-19 Vaccine (see Full
EUA Prescribing Information).
Thrombosis with Thrombocytopenia
Do not administer the Janssen COVID-19 Vaccine to individuals with a history of thrombosis with
thrombocytopenia following the Janssen COVID-19 Vaccine or any other adenovirus-vectored
COVID-19 vaccines (e.g., AstraZeneca’s COVID-19 vaccine which is not authorized or approved
in the United States) (see Full EUA Prescribing Information).
WARNINGS
Management of Acute Allergic Reactions
Appropriate medical treatment to manage immediate allergic reactions must be immediately
available in the event an acute anaphylactic reaction occurs following administration of the Janssen
COVID-19 Vaccine.
REVOKED
Revised: March/13/2023

Monitor Janssen COVID-19 Vaccine recipients for the occurrence of immediate adverse reactions
according to the Centers for Disease Control and Prevention guidelines
(https://www.cdc.gov/vaccines/covid-19/clinical-considerations/managing-anaphylaxis.html).
Thrombosis with Thrombocytopenia Syndrome (TTS)
Reports to the Vaccine Adverse Events Reporting System (VAERS), a passive surveillance
system, provide evidence for an increased risk of thrombosis with thrombocytopenia syndrome
(TTS) with onset of symptoms approximately one to two weeks after administration of the Janssen
COVID-19 Vaccine. An analysis of VAERS reports of TTS following the receipt of the Janssen
COVID-19 Vaccine used the following case definition:
• a thrombosis in an unusual location for a thrombus (i.e., cerebral vein, visceral artery or
vein, extremity artery, central artery or vein) and new-onset thrombocytopenia (i.e.,
platelet count <150,000/μL) occurring any time after vaccination;
or
• new-onset thrombocytopenia (i.e., platelet count <150,000/μL), thrombosis in an
extremity vein or pulmonary artery in the absence of thrombosis at an unusual location,
and a positive anti-PF4 antibody ELISA test or functional Heparin-Induced
Thrombocytopenia (HIT) platelet test occurring any time after vaccination.
Cases of TTS following administration of the Janssen COVID-19 Vaccine have been reported in
males and females, in a wide age range of individuals 18 years and older, with the highest reporting
rate (approximately 8 cases per 1,000,000 doses administered) in females ages 30-49 years;
overall, approximately 15% of TTS cases have been fatal. Currently available evidence supports a
causal relationship between TTS and the Janssen COVID-19 Vaccine. The clinical course of these
events shares features with autoimmune heparin-induced thrombocytopenia. In individuals with
suspected TTS following administration of the Janssen COVID-19 Vaccine, the use of heparin
may be harmful and alternative treatments may be needed. Consultation with hematology
specialists is strongly recommended. The American Society of Hematology has published
considerations relevant to the diagnosis and treatment of TTS following administration of the
Janssen COVID-19 Vaccine (https://www.hematology.org/covid-19/vaccine-induced-immune-
thrombotic-thrombocytopenia). (see Full EUA Prescribing Information).
Immune Thrombocytopenia (ITP)
Reports of adverse events following use of the Janssen COVID-19 Vaccine under emergency use
authorization suggest an increased risk of immune thrombocytopenia (ITP) during the 42 days
following vaccination. Individuals with a history of ITP should discuss with their healthcare
provider the risk of ITP and the potential need for platelet monitoring following vaccination with
the Janssen COVID-19 Vaccine.
Guillain-Barré Syndrome
Reports of adverse events following use of the Janssen COVID-19 Vaccine under emergency use
authorization suggest an increased risk of Guillain-Barré syndrome during the 42 days following
vaccination.
REVOKED
Revised: March/13/2023
6
Myocarditis and Pericarditis
Reports of adverse events following use of the Janssen COVID-19 Vaccine under emergency use
authorization suggest increased risks of myocarditis and pericarditis, particularly within the period
0 through 7 days following vaccination.
The CDC has published considerations related to myocarditis and pericarditis after vaccination,
including for vaccination of individuals with a history of myocarditis or pericarditis
(https://www.cdc.gov/vaccines/covid-19/clinical-considerations/interim-considerations-
us.html#myocarditis-pericarditis).
Altered Immunocompetence
Immunocompromised persons, including individuals receiving immunosuppressant therapy, may
have a diminished immune response to the Janssen COVID-19 Vaccine.
Syncope
Syncope (fainting) may occur in association with administration of injectable vaccines. Procedures
should be in place to avoid injury from fainting.
Limitations of Vaccine Effectiveness
The Janssen COVID-19 Vaccine may not protect all vaccinated individuals.
ADVERSE REACTIONS
Adverse Reactions in Clinical Trials
Adverse reactions reported in a clinical trial following administration of the Janssen COVID-19
Vaccine include injection site pain, headache, fatigue, myalgia, nausea, fever, injection site
erythema and injection site swelling. In clinical studies, severe allergic reactions, including
anaphylaxis, have been reported following administration of the Janssen COVID-19 Vaccine (see
Full EUA Prescribing Information).
Adverse Reactions Identified during Post Authorization Use
Anaphylaxis and other severe allergic reactions, thrombosis with thrombocytopenia, immune
thrombocytopenia, Guillain-Barré syndrome, myocarditis, pericarditis, and capillary leak
syndrome have been reported following administration of the Janssen COVID-19 Vaccine during
mass vaccination outside of clinical trials (see Full EUA Prescribing Information).
Additional adverse reactions, some of which may be serious, may become apparent with more
widespread use of the Janssen COVID-19 Vaccine.
USE WITH OTHER VACCINES
There is no information on the co-administration of the Janssen COVID-19 Vaccine with other
vaccines.

4.2 Thrombosis with Thrombocytopenia
Do not administer the Janssen COVID-19 Vaccine to individuals with a history of thrombosis with
thrombocytopenia following the Janssen COVID-19 Vaccine or any other adenovirus-vectored
COVID-19 vaccine (e.g., AstraZeneca’s COVID-19 vaccine which is not authorized or approved
in the United States) [see Warnings and Precautions (5.2)].
5 WARNINGS AND PRECAUTIONS
5.1 Management of Acute Allergic Reactions
Appropriate medical treatment used to manage immediate allergic reactions must be immediately
available in the event an acute anaphylactic reaction occurs following administration of the Janssen
COVID-19 Vaccine.
Monitor Janssen COVID-19 Vaccine recipients for the occurrence of immediate adverse reactions
according to the Centers for Disease Control and Prevention guidelines
(https://www.cdc.gov/vaccines/covid-19/clinical-considerations/managing-anaphylaxis.html).
5.2 Thrombosis with Thrombocytopenia Syndrome (TTS)
Reports to the Vaccine Adverse Events Reporting System (VAERS), a passive surveillance
system, provide evidence for an increased risk of thrombosis with thrombocytopenia syndrome
(TTS) with onset of symptoms approximately one to two weeks after administration of the Janssen
COVID-19 Vaccine.
An analysis of VAERS reports of TTS following the receipt of the Janssen COVID-19 Vaccine
used the following case definition:
• a thrombosis in an unusual location for a thrombus (i.e., cerebral vein, visceral artery or vein,
extremity artery, central artery or vein) and new-onset thrombocytopenia (i.e., platelet count
<150,000/μL) occurring any time after vaccination;
or
• new-onset thrombocytopenia (i.e., platelet count <150,000/μL), thrombosis in an extremity
vein or pulmonary artery in the absence of thrombosis at an unusual location, and a positive
anti-PF4 antibody ELISA test or functional HIT (heparin-induced thrombocytopenia) platelet
test occurring any time after vaccination.
Cases of TTS following administration of the Janssen COVID-19 Vaccine have been reported in
males and females, in a wide age range of individuals 18 years and older, with the highest reporting
rate (approximately 8 cases per 1,000,000 doses administered) in females ages 30-49 years;
overall, approximately 15% of TTS cases have been fatal. The clinical course of these events
shares features with autoimmune heparin-induced thrombocytopenia. Specific risk factors for TTS
following administration of the Janssen COVID-19 Vaccine and the level of potential excess risk
due to vaccination are under investigation. Currently available evidence supports a causal
relationship between TTS and the Janssen COVID-19 Vaccine.
Healthcare professionals should be alert to the signs and symptoms of TTS in individuals who
receive the Janssen COVID-19 Vaccine. In individuals with suspected TTS following

administration of the Janssen COVID-19 Vaccine, the use of heparin may be harmful and
alternative treatments may be needed. Consultation with hematology specialists is strongly
recommended.
The American Society of Hematology has published considerations relevant to the diagnosis and
treatment of TTS following administration of the Janssen COVID-19 Vaccine
(https://www.hematology.org/covid-19/vaccine-induced-immune-thrombotic-thrombocytopenia).
Recipients of Janssen COVID-19 Vaccine should be instructed to seek immediate medical
attention if they develop shortness of breath, chest pain, leg swelling, persistent abdominal pain,
neurological symptoms (including severe or persistent headaches or blurred vision), or petechiae
beyond the site of vaccination.
5.3 Immune Thrombocytopenia (ITP)
Reports of adverse events following use of the Janssen COVID-19 Vaccine under emergency use
authorization suggest an increased risk of immune thrombocytopenia (ITP) during the 42 days
following vaccination. Individuals with a history of ITP should discuss with their healthcare
provider the risk of ITP and the potential need for platelet monitoring following vaccination with
the Janssen COVID-19 Vaccine.
5.4 Guillain-Barré Syndrome
Reports of adverse events following use of the Janssen COVID-19 Vaccine under emergency use
authorization suggest an increased risk of Guillain-Barré syndrome during the 42 days following
vaccination.
5.5 Myocarditis and Pericarditis
Reports of adverse events following use of the Janssen COVID-19 Vaccine under emergency use
authorization suggest increased risks of myocarditis and pericarditis, particularly within the period
0 through 7 days following vaccination.
The CDC has published considerations related to myocarditis and pericarditis after vaccination,
including for vaccination of individuals with a history of myocarditis or pericarditis
(https://www.cdc.gov/vaccines/covid-19/clinical-considerations/interim-considerations-
us.html#myocarditis-pericarditis).
5.6 Syncope
Syncope (fainting) may occur in association with administration of injectable vaccines. Procedures
should be in place to avoid injury from fainting.
5.7 Altered Immunocompetence
Immunocompromised persons, including individuals receiving immunosuppressant therapy, may
have a diminished immune response to the Janssen COVID-19 Vaccine.
5.8 Limitations of Vaccine Effectiveness
The Janssen COVID-19 Vaccine may not protect all vaccinated individuals.

6 OVERALL SAFETY SUMMARY
It is MANDATORY for vaccination providers to report to the Vaccine Adverse Event
Reporting System (VAERS) all vaccine administration errors, all serious adverse events,
cases of myocarditis, cases of pericarditis, cases of Multisystem Inflammatory Syndrome
(MIS) in adults, and hospitalized or fatal cases of COVID-19 following vaccination with the
Janssen COVID-19 Vaccine. To the extent feasible, provide a copy of the VAERS form to
Janssen Biotech, Inc. Please see the REQUIREMENTS AND INSTRUCTIONS FOR
REPORTING ADVERSE EVENTS AND VACCINE ADMINISTRATION ERRORS
section for details on reporting to VAERS or Janssen Biotech, Inc.
Adverse Reactions in Clinical Trials
In study COV3001, the most common local solicited adverse reaction (≥10%) reported was
injection site pain (48.6%). The most common systemic adverse reactions (≥10%) were headache
(38.9%), fatigue (38.2%), myalgia (33.2%), and nausea (14.2%) (see Tables 1 to 4).
Severe allergic reactions, including anaphylaxis, have been reported following administration of
the Janssen COVID-19 vaccine.
Adverse Reactions Identified during Post Authorization Use
Anaphylaxis and other severe allergic reactions, thrombosis with thrombocytopenia, immune
thrombocytopenia, Guillain-Barré syndrome, myocarditis, pericarditis, and capillary leak
syndrome have been reported following administration of the Janssen COVID-19 Vaccine during
mass vaccination outside of clinical trials.
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates
observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of
another drug and may not reflect the rates observed in practice.
Safety Primary vaccination
The safety of the Janssen COVID-19 Vaccine has been assessed in an ongoing Phase 3 Study,
COV3001 (NCT04505722) (Study 1). A total of 43,783 individuals were enrolled in this study, of
whom 21,895 adults aged 18 years and older received the Janssen COVID-19 Vaccine [Full
Analysis Set (FAS)]. This study is being conducted in the United States (n=19,302), Brazil
(n=7,278), South Africa (n=6,576), Colombia (n=4,248), Argentina (n=2,996), Peru (n=1,771),
Chile (n=1,133), Mexico (n=479). In this study, 45.0% were female, 54.9% were male, 58.7%
were White, 19.4% were Black or African American, 45.3% were Hispanic or Latino, 3.3% were
Asian, 9.5% were American Indian/Alaska Native and 0.2% were Native Hawaiian or other Pacific
Islander, 5.6% were from multiple racial groups and 1.4% were unknown races (see Table 5). The
median age of individuals was 52.0 years (range: 18-100). There were 4,217 (9.6%) individuals
who were SARS-CoV-2 seropositive at baseline and who were included in the study. In the United
States, 838 of 19,302 (4.3%) individuals were SARS-CoV-2 seropositive. Demographic
characteristics were similar among individuals who received the Janssen COVID-19 Vaccine and
those who received saline placebo.

The safety subset includes 6,736 individuals (3,356 from the Janssen COVID-19 Vaccine group,
3,380 from the placebo group). The demographic profile in the safety subset was similar in terms
of age and gender compared to the FAS. A larger percentage of individuals in the safety subset
were White (83.4%) compared to the FAS (58.7%). Geographically, the safety subset was limited
to individuals from the United States (51.4%), Brazil (38.5%) and South Africa (10.2%). Fewer
individuals in the safety subset compared to the FAS were SARS-CoV-2 seropositive at baseline,
4.5% vs. 9.6%, and had at least one comorbidity 34.1% vs 40.8%.
Safety monitoring in the clinical study consisted of monitoring for: (1) solicited local and systemic
reactions occurring in the 7 days following vaccination in a subset of individuals (safety subset),
(2) unsolicited adverse events (AEs) occurring in the 28 days following vaccination in the safety
subset, (3) medically-attended AEs (MAAEs) occurring in the 6 months following vaccination in
the entire study population (FAS), (4) serious AEs (SAEs) and AEs leading to study
discontinuation for the duration of the study in the entire study population.

Solicited local and systemic adverse reactions reported following administration of the Janssen
COVID-19 Vaccine had a median duration of 1 to 2 days.
Unsolicited adverse events
Individuals within the safety subset in Study 1 (N=6,736) were monitored for unsolicited adverse
events (AEs) for 28 days following vaccination with 99.9% (N= 6,730) of individuals completing
the full 28 days of follow-up. The proportion of individuals who reported one or more unsolicited
AEs was similar among those in the Janssen COVID-19 Vaccine group (13.1%) and those in the
placebo group (12.0%).
Serious Adverse Events (SAEs) and other events of interest
In Study 1, up to a cut-off date of January 22, 2021, 54.6% of individuals had follow-up duration
of 8 weeks. The median follow-up duration for all individuals was 58 days. SAEs, excluding those
related to confirmed COVID-19, were reported by 0.4% (n=83) of individuals who received the
Janssen COVID-19 Vaccine (N= 21,895) and 0.4% (n=96) of individuals who received placebo
(N= 21,888).
Additional adverse events of interest, including but not limited to allergic, neurologic,
inflammatory, vascular, and autoimmune disorders, were analyzed among all adverse events
collected through protocol-specified safety monitoring procedures as well as unsolicited reporting.
Urticaria (all non-serious) was reported in five vaccinated individuals and 1 individual who
received placebo in the 7 days following vaccination. In addition, an SAE of hypersensitivity, not
classified as anaphylaxis, was reported in 1 vaccinated individual with urticaria beginning
REVOKED
Revised: March/13/2023
20
two days following vaccination and angioedema of the lips with no respiratory distress beginning
four days following vaccination. The event was likely related to the vaccine.
An SAE of severe pain in the injected arm, not responsive to analgesics, with immediate onset at
time of vaccination, and that was ongoing 74 days following vaccination was reported in an
individual who received the Janssen COVID-19 Vaccine. An SAE of severe generalized weakness,
fever, and headache, with onset on the day following vaccination and resolution three days
following vaccination was reported in an individual who received the Janssen COVID-19 Vaccine.
Both SAEs are likely related to the vaccine.
Numerical imbalances, with more events in vaccine than placebo recipients, were observed for the
following serious and other adverse events of interest in individuals receiving the vaccine or
placebo, respectively:
• Thromboembolic events:
• Deep vein thrombosis: 6 events (2 serious; 5 within 28 days of vaccination) vs.
2 events (1 serious; 2 within 28 days of vaccination).
• Pulmonary embolism: 4 events (3 serious; 2 within 28 days of vaccination) vs. 1 event
(serious and within 28 days of vaccination).
• Transverse sinus thrombosis with thrombocytopenia: 1 event (serious, with onset of
symptoms 8 days post- vaccination) vs. 0.
• Seizures: 4 events (1 serious; 4 within 28 days of vaccination) vs. 1 event (0 serious and
0 within 28 days following vaccination).
• Tinnitus: 6 events (0 serious; 6 within 28 days of vaccination, including 3 within 2 days of
vaccination) vs. 0.
For these events, a causal relationship with the Janssen COVID-19 vaccine could not be
determined based on Study 1. The assessment of causality was confounded by the presence of
underlying medical conditions that may have predisposed individuals to these events. However,
post-authorization experience supports a causal relationship with Janssen COVID-19 Vaccine for
the event of transverse sinus thrombosis with thrombocytopenia [see Contraindications (4.2),
Warnings and Precautions (5.2) and Overall Safety Summary (6.2)].
There were no additional notable patterns or numerical imbalances between treatment groups for
specific categories of serious adverse events (including neurologic, neuro-inflammatory, and
cardiovascular events) that would suggest a causal relationship to the Janssen COVID-19 Vaccine.
Booster Dose Following Primary Vaccination with Janssen COVID-19 Vaccine
Overall, in 5 clinical studies conducted in Belgium, Brazil, Colombia, France, Germany, Japan,
Netherlands, Philippines, South Africa, Spain, United Kingdom and United States, approximately
9,000 participants have received 2 doses of the Janssen COVID-19 Vaccine, administered at least
2 months apart and approximately 2,700 participants had at least 2 months of safety follow-up
after the booster dose.

A randomized, double-blind, placebo-controlled Phase 2 study, COV2001 (NCT04535453)
(Study 2), evaluated the frequency and severity of local and systemic adverse reactions within
7 days of administration of a booster dose of the Janssen COVID-19 Vaccine administered
approximately 2 months after the primary vaccination in healthy adults 18 through 55 years of age
and adults 65 years and older in good or stable health. A total of 141 individuals received at least
one dose of the vaccine and 137 received both the primary vaccination and the booster dose at an
interval of 2 months. The median age of individuals was 48 years, and 48 individuals (34%) were
65 years of age and older. Data on solicited adverse reactions after the primary vaccination and
after a booster dose are shown in Tables 5-8.

Unsolicited adverse events
An overall assessment of Janssen’s safety analyses from studies evaluating 2 doses of Janssen
COVID-19 Vaccine did not reveal new safety concerns following a booster dose, as compared
with adverse reactions reported following the single-dose primary vaccination.
Booster Dose Following Primary Vaccination with Another Authorized or Approved COVID-19
Vaccine
The safety of a Janssen COVID-19 Vaccine booster dose in individuals who completed primary
vaccination with another authorized or approved COVID-19 Vaccine (heterologous booster dose)
is inferred from the safety of a Janssen COVID-19 Vaccine booster dose administered following
completion of Janssen COVID-19 Vaccine primary vaccination (homologous booster dose) and
from data from an independent Phase 1/2 open-label clinical trial (NCT04889209) conducted in
the United States that evaluated a heterologous booster dose of the Janssen COVID-19 Vaccine.
In this study, adults who had completed primary vaccination with a Moderna COVID-19 Vaccine
2-dose series (N=151), a Janssen COVID-19 Vaccine single-dose (N=156), or a Pfizer-BioNTech
COVID-19 Vaccine 2-dose series (N=151) at least 12 weeks prior to enrollment and who reported
no history of SARS-CoV-2 infection were randomized 1:1:1 to receive a booster dose of one of
three vaccines: Moderna COVID-19 Vaccine, Janssen COVID-19 Vaccine, or Pfizer-BioNTech
COVID-19 Vaccine. Adverse events were assessed through 28 days after the booster dose. An
overall review of adverse reactions reported following the Janssen COVID-19 Vaccine
heterologous booster dose did not identify any new safety concerns, as compared with adverse
reactions reported following a Janssen COVID-19 Vaccine primary vaccination or homologous
booster dose.
6.2 Post Authorization Experience
The following adverse reactions have been identified during post-authorization use of the Janssen
COVID-19 Vaccine. Because these reactions are reported voluntarily, it is not always possible to
reliably estimate their frequency or establish a causal relationship to vaccine exposure.
Blood and Lymphatic System Disorders: Thrombosis with thrombocytopenia,
Lymphadenopathy, Immune thrombocytopenia.
Cardiac disorders: Myocarditis, Pericarditis.
Ear and labyrinth disorders: Tinnitus.
Gastrointestinal disorders: Diarrhea, Vomiting.
Immune System Disorders: Allergic reactions, including anaphylaxis.
Nervous System Disorders: Guillain-Barré syndrome, Syncope, Paresthesia, Hypoesthesia, Facial
Paralysis (including Bell’s Palsy).
Vascular Disorders: Capillary leak syndrome, Thrombosis with thrombocytopenia, Venous
thromboembolism (with or without thrombocytopenia).

10 DRUG INTERACTIONS
There are no data to assess the concomitant administration of the Janssen COVID-19 Vaccine with
other vaccines.
11 USE IN SPECIFIC POPULATIONS
11.1 Pregnancy
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to
Janssen COVID-19 Vaccine during pregnancy. Women who are vaccinated with Janssen
COVID-19 Vaccine during pregnancy are encouraged to enroll in the registry by visiting
https://c-viper.pregistry.com.
Risk Summary
All Pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the U.S. general
population, the estimated background risk of major birth defects and miscarriage in clinically
recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Available data on Janssen COVID-19 Vaccine administered to pregnant women are insufficient to
inform vaccine-associated risks in pregnancy.
In a reproductive developmental toxicity study female rabbits were administered 1 mL of the
Janssen COVID-19 Vaccine (a single human dose is 0.5 mL) by intramuscular injection 7 days
prior to mating and on Gestation Days 6 and 20 (i.e., one vaccination during early and late
gestation, respectively). No vaccine related adverse effects on female fertility, embryo-fetal or
postnatal development up to Postnatal Day 28 were observed.
11.2 Lactation
Risk Summary
Data are not available to assess the effects of Janssen COVID-19 Vaccine on the breastfed infant
or on milk production/excretion.
11.3 Pediatric Use
Emergency Use Authorization of the Janssen COVID-19 Vaccine does not include use in
individuals younger than 18 years of age.
11.4 Geriatric Use
Clinical studies of Janssen COVID-19 Vaccine included individuals 65 years of age and older and
their data contributes to the overall assessment of safety and efficacy [see Overall Safety Summary
(6.1) and Clinical Trial Results and Supporting Data for EUA (18)]. Of the 21,895 individuals
who received a single-dose of the Janssen COVID-19 Vaccine in COV3001, 19.5% (n=4,259)
were 65 years of age and older and 3.7% (n=809) were 75 years of age and older. No overall

differences in safety or efficacy were observed between individuals 65 years of age and older and
younger individuals.
13 DESCRIPTION
The Janssen COVID-19 Vaccine is a colorless to slightly yellow, clear to very opalescent sterile
suspension for intramuscular injection. It contains no visible particulates. The vaccine consists of
a replication-incompetent recombinant adenovirus type 26 (Ad26) vector expressing the severe
acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spike (S) protein in a stabilized
conformation.
The Ad26 vector expressing the SARS-CoV-2 S protein is grown in PER.C6 TetR cells, in media
containing amino acids and no animal-derived proteins. After propagation, the vaccine is
processed through several purification steps, formulated with inactive ingredients and filled into
vials.
Each 0.5 mL dose of Janssen COVID-19 Vaccine is formulated to contain 5×10
10
virus particles
(VP) and the following inactive ingredients: citric acid monohydrate (0.14 mg), trisodium citrate
dihydrate (2.02 mg), ethanol (2.04 mg), 2-hydroxypropyl-β-cyclodextrin (HBCD) (25.50 mg),
polysorbate-80 (0.16 mg), sodium chloride (2.19 mg). Each dose may also contain residual
amounts of host cell proteins (≤0.15 mcg) and/or host cell DNA (≤3 ng).
Janssen COVID-19 Vaccine does not contain a preservative.
The vial stoppers are not made with natural rubber latex.
14 CLINICAL PHARMACOLOGY
14.1 Mechanism of Action
The Janssen COVID-19 Vaccine is composed of a recombinant, replication-incompetent human
adenovirus type 26 vector that, after entering human cells, expresses the SARS-CoV-2 spike (S)
antigen without virus propagation. An immune response elicited to the S antigen protects against
COVID-19.
18 CLINICAL TRIAL RESULTS AND SUPPORTING DATA FOR EUA
18.1 Efficacy of Primary Vaccination
A primary analysis (cut-off date January 22, 2021) of a multicenter, randomized, double-blind,
placebo-controlled Phase 3 Study (Study 1) was conducted in the United States, South Africa,
Brazil, Chile, Argentina, Colombia, Peru and Mexico to assess the efficacy, safety, and
immunogenicity of a single-dose of the Janssen COVID-19 Vaccine for the prevention of
COVID-19 in adults aged 18 years and older. Randomization was stratified by age (18-59 years,
60 years and older) and presence or absence of comorbidities associated with an increased risk of
progression to severe COVID-19. The study allowed for the inclusion of individuals with stable
pre-existing medical conditions, defined as disease not requiring significant change in therapy
during the 3 months preceding vaccination, as well as individuals with stable human
immunodeficiency virus (HIV) infection.

A total of 44,325 individuals were randomized equally to receive Janssen COVID-19 Vaccine or
saline placebo. Individuals are planned to be followed for up to 24 months, for assessments of
safety and efficacy against COVID-19.
The primary efficacy analysis population of 39,321 individuals (19,630 in the Janssen COVID-19
Vaccine group and 19,691 in the placebo group) included 38,059 SARS-CoV-2 seronegative
individuals at baseline and 1,262 individuals with an unknown serostatus. Demographic and
baseline characteristics were similar among individuals who received the Janssen COVID-19
Vaccine and those who received placebo (see Table 9).

Efficacy Against COVID-19
The co-primary endpoints evaluated the first occurrence of moderate to severe/critical COVID-19
with onset of symptoms at least 14 days and at least 28 days after vaccination. Moderate to
severe/critical COVID-19 was molecularly confirmed by a central laboratory based on a positive
SARS-CoV-2 viral RNA result using a polymerase chain reaction (PCR)-based test.
• Moderate COVID-19 was defined based on the following criteria: the individual must have
experienced any one of the following new or worsening signs or symptoms: respiratory rate

≥20 breaths/minute, abnormal saturation of oxygen (SpO2) but still >93% on room air at sea
level, clinical or radiologic evidence of pneumonia, radiologic evidence of deep vein
thrombosis (DVT), shortness of breath or difficulty breathing OR any two of the following
new or worsening signs or symptoms: fever (≥38.0°C or ≥100.4°F), heart rate
≥90 beats/minute, shaking chills or rigors, sore throat, cough, malaise, headache, muscle
pain (myalgia), gastrointestinal symptoms, new or changing olfactory or taste disorders, red
or bruised appearing feet or toes.
• Severe/critical COVID-19 was defined based on the following criteria: the individual must
have experienced any one of the following at any time during the course of observation:
clinical signs at rest indicative of severe systemic illness (respiratory rate
≥30 breaths/minute, heart rate ≥125 beats/minute, oxygen saturation (SpO2) ≤93% on room
air at sea level, or partial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2)
<300 mmHg), respiratory failure (defined as needing high-flow oxygen, non-invasive
ventilation, mechanical ventilation, or extracorporeal membrane oxygenation [ECMO]),
evidence of shock (defined as systolic blood pressure <90 mmHg, diastolic blood pressure
<60 mmHg, or requiring vasopressors), significant acute renal, hepatic, or neurologic
dysfunction, admission to intensive care unit (ICU), death.
Final determination of severe/critical COVID-19 cases were made by an independent adjudication
committee.
Primary analysis
The median length of follow up for efficacy for individuals in the study was 8 weeks
post-vaccination. Vaccine Efficacy (VE) for the co-primary endpoints against moderate to
severe/critical COVID-19 in individuals who were seronegative or who had an unknown serostatus
at baseline was 66.9% (95% CI: 59.0; 73.4) at least 14 days after vaccination and 66.1% (95% CI:
55.0; 74.8) at least 28 days after vaccination (see Table 10).

Janssen COVID-19 Vaccine Efficacy in Countries With Different Circulating SARS-CoV-2
Variants.
Exploratory subgroup analyses of vaccine efficacy against moderate to severe/critical COVID-19
and severe/critical COVID-19 for Brazil, South Africa, and the United States were conducted (see
Table 12). For the subgroup analyses, all COVID-19 cases accrued up to the primary efficacy
analysis data cut-off date, including cases confirmed by the central laboratory and cases with
documented positive SARS-CoV-2 PCR from a local laboratory which are still awaiting
confirmation by the central laboratory, were included. The concordance rate observed up to the
data cut-off date between the PCR results from the local laboratory and the central laboratory was
90.3%.

71.7% of central laboratory confirmed primary analysis cases had been sequenced [United States
(73.5%), South Africa (66.9%) and Brazil (69.3%)]. In the United States, 96.4% of strains were
identified as the Wuhan-H1 variant D614G; in South Africa, 94.5% of strains were identified as
the 20H/501Y.V2 variant (B.1.351 lineage); in Brazil, 69.4% of strains were identified to be a
variant of the P.2 lineage and 30.6% of strains were identified as the Wuhan-H1 variant D614G.
As of February 12, 2021, SARS-CoV-2 variants from the B1.1.7 or P.1 lineages were not found in
any of the sequenced samples.
18.2 Immunogenicity of a Booster Dose following Primary Vaccination with Janssen
COVID-19 Vaccine
In Study 2, individuals 18 through 55 years of age and 65 years and older received a booster dose
of the Janssen COVID-19 Vaccine approximately 2 months after the primary vaccination.
Immunogenicity was assessed by measuring neutralizing antibodies to SARS-CoV-2
Victoria/1/2020 strain using a qualified wild-type virus neutralization assay (wtVNA).
Immunogenicity data are available from 39 individuals, of whom 15 were 65 years of age and
older, and are summarized in Table 13. Based on a limited number of individuals from this study,
a similar fold-rise in neutralizing antibody titers from pre-booster to 14 and 28 days post-booster

PPI set: The per protocol immunogenicity population includes all randomized and vaccinated participants for whom immunogenicity data
are available excluding participants with major protocol deviations expected to impact the immunogenicity outcomes. In addition,
samples obtained after missed vaccinations or participants with SARS-CoV-2 infection occurring after screening were excluded from the
analysis.
When evaluated descriptively among a limited number of study participants using an ELISA assay,
increases in anti-Spike protein binding IgG antibodies post booster were not lower for an interval
of 6 months compared with an interval of 2 months between primary vaccination and booster dose.
These data support the effectiveness of a booster dose when administered at an interval of longer
than 2 months after primary vaccination.
18.3 Immunogenicity of a Booster Dose Following Primary Vaccination with Another
Authorized or Approved COVID-19 Vaccine
Effectiveness of a Janssen COVID-19 Vaccine booster dose in individuals who completed primary
vaccination with another authorized or approved COVID-19 Vaccine (heterologous booster dose)
is inferred from immunogenicity data supporting effectiveness of a Janssen COVID-19 Vaccine
booster dose administered following completion of Janssen COVID-19 Vaccine primary
vaccination and from immunogenicity data from an independent Phase 1/2 open-label clinical trial
(NCT04889209) conducted in the United States that evaluated a heterologous booster dose of the
Janssen COVID-19 Vaccine. In this study, adults who had completed primary vaccination with a
Moderna COVID-19 Vaccine 2-dose series (N=151), a Janssen COVID-19 Vaccine single-dose
(N=156), or a Pfizer-BioNTech COVID-19 Vaccine 2-dose series (N=151) at least 12 weeks prior
to enrollment and who reported no history of SARS-CoV-2 infection were randomized 1:1:1 to
receive a booster dose of one of three vaccines: Moderna COVID-19 Vaccine, Janssen COVID-19
Vaccine, or Pfizer-BioNTech COVID-19 Vaccine. Neutralizing antibody titers, as measured by a
pseudovirus neutralization assay using a lentivirus expressing the SARS-CoV-2 Spike protein with
D614G mutation, were assessed on Day 1 prior to administration of the booster dose and on Day 15

after the booster dose. A booster response to the Janssen COVID-19 Vaccine was demonstrated
regardless of primary vaccination.
19 HOW SUPPLIED/STORAGE AND HANDLING
Janssen COVID-19 Vaccine is supplied in a carton of 10 multi-dose vials (NDC 59676-580-15).
A maximum of 5 doses can be withdrawn from the multi-dose vial.
The storage and handling information in this Fact Sheet supersedes the storage and handling
information on the carton and vial labels.
Storage Prior to First Puncture of the Vaccine Vial
Store unpunctured multi-dose vials of the Janssen COVID-19 Vaccine at 2°C to 8°C (36°F to
46°F) and protect from light. Do not store frozen.
Unpunctured vials of Janssen COVID-19 Vaccine may be stored between 9°C to 25°C (47°F to
77°F) for up to 12 hours.
The Janssen COVID-19 Vaccine is initially stored frozen by the manufacturer, then shipped at 2°C
to 8°C (36°F to 46°F). If vaccine is still frozen upon receipt, thaw at 2°C to 8°C (36°F to 46°F). If
needed immediately, thaw at room temperature (maximally 25°C/77°F). At room temperature
(maximally 25°C/77°F), a carton of 10 vials will take approximately 4 hours to thaw, and an
individual vial will take approximately 1 hour to thaw. Do not refreeze once thawed.
Storage After First Puncture of the Vaccine Vial
After the first dose has been withdrawn, hold the vial between 2° to 8°C (36° to 46°F) for up to
6 hours or at room temperature (maximally 25°C/77°F) for up to 2 hours. Discard the vial if
vaccine is not used within these times.
