5 2.2 Administration Information 
 
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to 
administration, whenever solution and container permit. The vac cine will be a white to off-white suspension. 
Do not administer if vaccine is discolored or contains particul ate matter. 
 Administer a single 0.3 mL dose of COMIRNATY intramuscularly. 
 Vials of COMIRNATY with gray cap s and labels with gray borders contain 6 doses of 0.3 mL of vaccine. Low 
dead-volume syringes and/or needles can be used to extract 6 do ses from a single vial. If standard syringes and 
needles are used, there may not be sufficient volume to extract 6 doses from a single vial. Irrespective of the 
type of syringe and needle, 
• each dose must contain 0.3 mL of vaccine. 
• if the amount of vaccine remaining in the vial cannot provide a  full dose of 0.3 mL, discard the vial and 
any excess volume.  
• do not pool excess vaccine from multiple vials. 
 2.3 Vaccination Schedule  
COMIRNATY is administered intramuscularly as a series of 2 dose s (0.3 mL each) 3 weeks apart. 
 
There are no data available on the interchangeability of COMIRN ATY with COVID-19 vaccines from other 
manufacturers to complete the vaccination series. Individuals w ho have received 1 dose of COMIRNATY should 
receive a second dose of COMIRNATY to complete the vaccination series. 
 
3 DOSAGE FORMS AND STRENGTHS 
 
COMIRNATY is a suspension for injection. Each dose of COMIRNATY  supplied in vials with gray caps and 
labels with gray borders is 0.3 mL. 
 
4 CONTRAINDICATIONS 
 Do not administer COMIRNATY to individuals with known history o f a severe allergic reaction (e.g., 
anaphylaxis) to any component of the COMIRNATY  [see Description (11)] . 
 
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 admin istration of COMIRNATY.  
 5.2 Myocarditis and Pericarditis 
 Postmarketing data demonstrate increased risks of myocarditis a nd pericarditis, particularly within 7 days 
following the second dose. The observed risk is higher among ma les under 40 years of age than among females 
and older males. The observed risk is highest in males 12 through 17 years of age. Although some cases required intensive care support, available data from short-term follow-up suggest that most individuals have had 
resolution of symptoms with conservative management. Information is not yet available about potential long-
term sequelae. The CDC has published considerations related to myocarditis and pericarditis after vaccination, 
FDA-CBER-2022-5812-0236006
 
6 including for vaccination of individuals with a history of myocarditis or pericarditis 
(https://www.cdc.gov/vaccines/covid-19/clinical-considerations/m yocarditis.html ). 
 
5.3 Syncope 
 Syncope (fainting) may occur in association with administration of injectable vaccines, including 
COMIRNATY. Procedures should be in place to avoid injury from f ainting. 
 
5.4 Altered Immunocompetence 
 
Immunocompromised persons, including individuals receiving immu nosuppressant therapy, may have a 
diminished immune response to the COMIRNATY.  5.5
 Limitation of Effectiveness 
 COMIRNATY may not protect all vaccine recipients. 
 
6 ADVERSE REACTIONS  In clinical studies, the most commonly reported (≥10%) adverse reactions in participants 16 through 55 years of 
age following any dose were pain at the injection site (88.6%),  fatigue (70.1%), headache (64.9%), muscle pain 
(45.5%), chills (41.5%), joint pain (27.5%), fever (17.8%), and  injection site swelling (10.6%). 
 
In clinical studies, the most commonly reported (≥10%) adverse reactions in participants 56 years of age and 
older following any dose were pain at the injection site (78.2%), fatigue (56.9%), headache, (45.9%), muscle pain (32.5%), chills (24.8%), joint pain (21.5%), injection sit e swelling (11.8%), fever (11.5%), and injection 
site redness (10.4%). 
 In a clinical study, the most commonly reported (≥8%) adverse r eactions in adolescents 12 through 15 years of 
age following any dose were pain at the injection site (90.5%),  fatigue (77.5%), headache (75.5%), chills 
(49.2%), muscle pain (42.2%), fever (24.3%), joint pain (20.2%) , injection site swelling (9.2%), and injection 
site redness (8.6%). 
 
6.1 Clinical Trials Experience 
 
Because clinical trials are conducted under widely varying cond itions, adverse reaction rates observed in the 
clinical trials of a vaccine cannot be directly compared to rat es in the clinical trials of another vaccine and may 
not reflect the rates observed in practice. 
 
The safety of COMIRNATY was evaluated in participants 16 12 years of age and older in 2 clinical studies 
conducted in Germany (Study 1), United States, Argentina, Brazi l, Turkey, South Africa, and Germany 
(Study 2). Study BNT162-01 (Study 1) was a Phase 1/2, 2-part, d ose-escalation trial that enrolled 
60 participants, 18 through 55 years of age and 36 participants , 56 through 85 years of age. Study C4591001 
(Study 2) is a Phase 1/2/3 multicenter, multinational, randomiz ed, saline placebo-controlled, double-blinded 
(Phase 2/3), dose-finding, vaccine candidate-selection and efficacy study that has enrolled approximately 
44,04746,000 participants (22,026 COMIRNATY; 22,021 placebo) 1612  years of age or older . Of these, 
approximately 44,047 participants (22,026 COMIRNATY; 22,021 pla cebo) in Phase 2/3 are 16 years of age or 
older  (including 378 and 376 participants 16 through 17 years of age  in the vaccine COMIRNATY and placebo 
groups, respectively)  and 2,260 adolescents are 12 through 15 years of age (1,131 an d 1,129 in the 
COMIRNATY and placebo groups, respectively) . Upon issuance of the Emergency Use Authorization 
FDA-CBER-2022-5812-0236007
 
7 (December 11, 2020) for COMIRNATY, participants were unblinded to offer placebo par ticipants 
COMIRNATY. Participants were unblinded in a phased manner over a period of months to offer placebo 
participants COMIRNATY. Study 2 also included 200 participants with confirmed stable human 
immunodeficiency virus (HIV) infection; HIV-positive participan ts are included in safety population disposition 
but are summarized separately in safety analyses. Confirmed stable HIV infection was defined as documented 
viral load <50 copies/mL and CD4 count >200 cells/mm3 within 6 months before enrollment, and on stable 
antiretroviral therapy for at least 6 months.  
At the time of the analysis of the ongoing Study 2 with a data cut-off of March 13, 2021, there were 
25,651 (58.2%) participants (13,031 COMIRNATY and 12,620 placeb o) 16 years of age and older followed for 
≥4 months after the second dose. 
 In Study 2, all participants 12 through 15 years of age, and Pa rticipants 16 years and older in the reactogenicity 
subset were monitored for solicited local and systemic reactions and use of antipyretic medication after each 
vaccination in an electronic diary. Participants are being moni tored for unsolicited adverse events, including 
serious adverse events, throughout the study [from Dose 1 throu gh 1 month (all unsolicited adverse events) or 
6 months (serious adverse events) after the last vaccination].  Tables 1 through 6 present the frequency and 
severity of solicited local and systemic reactions, respectivel y, within 7 days following each dose of 
COMIRNATY and placebo.  
 
Participants 16 Years of Age and Older 
 
At the time of the analysis of the ongoing Study 2 with a data cutoff of March 13, 2021, there were 
25,651 (58.2%) participants (13,031 COMIRNATY and 12,620 placeb o) 16 years of age and older followed for 
≥4 months after the second dose. 
 Demographic characteristics in Study 2 were generally similar w ith regard to age, gender, race, and ethnicity 
among participants who received COMIRNATY and those who receive d placebo. Overall, among the total 
participants who received either  COMIRNATY or placebo, 50.9% we re male, 49.1% were female, 79.3% were 
16 through 64 years of age, 20.7% were 65 years of age and olde r, 82.0% were White, 9.6% were Black or 
African American, 25.9% were Hispanic/Latino, 4.3% were Asian, and 1.0% were American Indian or Alaska 
Native.  
 
Local and Systemic Adverse Reactions Solicited in the Study 2 
 
Table 1 and Table 2 present the frequency and severity of repor ted solicited local and systemic reactions, 
respectively, within 7 days following each dose of COMIRNATY and placebo in the subset of participants 
16 through 55 years of age included in the safety population wh o were monitored for reactogenicity with an 
electronic diary.  
 
Table 3 and Table 4 present the frequency and severity of repor ted solicited local and systemic reactions, 
respectively, within 7 days of each dose of COMIRNATY and place bo for participants 56 years of age and 
older. 
 
In participants 16 through 55 years of age after receiving Dose  2, the mean duration of pain at the injection site 
was 2.5 days (range 1 to 70 days), for redness 2.2 days (range 1 to 9 days), and for swelling 2.1 days (range 1 to 
8 days) for participants in the COMIRNATY group. In participant s 56 years of age and older after receiving 
Dose 2, the mean duration of pain at the injection site was 2.4 days (range 1 to 36 days), for redness 3.0 days 
(range 1 to 34 days), and for swelling 2.6 days (range 1 to 34 days) for participants in the COMIRNATY group.

Unsolicited Adverse Events 
 
Overall, 11,253 (51.1%) participants in the COMIRNATY group and  11,316 (51.4%) participants in the 
placebo group had follow-up time between ≥4 months to <6 months  after Dose 2 in the blinded 
placebo-controlled follow-up period with an additional 1,778 (8 .1%) and 1,304 (5.9%) with ≥6 months of 
blinded follow-up time in the COMIRNATY and placebo groups, res pectively.  
 
A total of 12,006 (54.5%) participants originally randomized to  COMIRNATY had ≥6 months total (blinded 
and unblinded) follow-up after Dose 2. 
 
In an analysis of all unsolicited adverse events reported follo wing any dose, through 1 month after Dose 2, in 
participants 16 years of age and older (N=43,847; 21,926 COMIRN ATY group vs. 21,921 placebo group), 
those assessed as adverse reactions not already captured by solicited local and systemic reactions were nausea 
(274 vs. 87), malaise (130 vs. 22), lymphadenopathy (83 vs. 7),  asthenia (76 vs. 25), decreased appetite 
(39 vs. 9), hyperhidrosis (31 vs. 9), lethargy (25 vs. 6), and night sweats (17 vs. 3). 
 
In analyses of all unsolicited adverse events in Study 2 from D ose 1 up to the participant unblinding date, 
58.2% of study participants had at least 4 months of follow-up after Dose 2. Among participants 16 through 
55 years of age who received at least 1 dose of study vaccine, 12,995 of whom received COMIRNATY and 
13,026 of whom received placebo, unsolicited adverse events wer e reported by 4,396 (33.8%) participants in 
the COMIRNATY group and 2,136 (16.4%) participants in the place bo group. In a similar analysis in 
participants 56 years of age and older that included 8,931 COMI RNATY recipients and 
8,895   placebo recipients, unsolicited adverse events were reported by  2,551 (28.6%) participants in the 
COMIRNATY group and 1,432 (16.1%) participants in the placebo g roup. Among participants with confirmed 
stable HIV infection that included 100 COMIRNATY recipients and  100 placebo recipients, unsolicited adverse 
events were reported by 29 (29%) participants in the COMIRNATY group and 15 (15%) participants in the 
placebo group. The higher frequency of reported unsolicited adv erse events among COMIRNATY recipients 
compared to placebo recipients was primarily attributed to even ts that are consistent with adverse reactions 
solicited among participants in the reactogenicity subset (Tabl e 3 and Table 4). 
 
Throughout the placebo-controlled safety follow-up period, Bell ’s palsy (facial paralysis) was reported by 
4 participants in the COMIRNATY group and 2 participants in the  placebo group. Onset of facial paralysis was 
Day 37 after Dose 1 (participant did not receive Dose 2) and Days 3, 9, and 48 after Dose 2. In the placebo 
group the onset of facial paralysis was Day 32 and Day 102. Cur rently available information is insufficient to 
determine a causal relationship with the vaccine. In the analys is of blinded, placebo-controlled follow-up, there 
were no other notable patterns or numerical imbalances between treatment groups for specific categories of 
non-serious adverse events (including other neurologic or neuro -inflammatory, and thrombotic events) that 
would suggest a causal relationship to COMIRNATY. In the analys is of unblinded follow-up, there were no

13 notable patterns of specific categories of non-serious adverse events that would suggest a causal relationship to 
COMIRNATY. 
 
Serious Adverse Events 
 
In Study 2, among participants 16 through 55 years of age who h ad received at least 1 dose of vaccine or 
placebo (COMIRNATY =12,995; placebo = 13,026), serious adverse events from Dose 1 up to the participant 
unblinding date in ongoing follow-up were reported by 103 (0.8%) COMIRNATY recipients and 117 (0.9%) 
placebo recipients. In a similar analysis, in participants 56 y ears of age and older (COMIRNATY = 8,931; 
placebo = 8,895), serious adverse events were reported by 165 ( 1.8%) COMIRNATY recipients and 151 (1.7%) 
placebo recipients who received at least 1 dose of COMIRNATY or  placebo, respectively. In these analyses, 
58.2% of study participants had at least 4 months of follow-up after Dose 2. Among participants with confirmed 
stable HIV infection serious adverse events from Dose 1 up to the participant unblinding date in ongoing 
follow-up were reported by 2 (2%) COMIRNATY recipients and 2 (2 %) placebo recipients.  
 
In the analysis of blinded, placebo-controlled follow-up, there  were no notable patterns between treatment 
groups for specific categories of serious adverse events (inclu ding neurologic, neuro-inflammatory, and 
thrombotic events) that would suggest a causal relationship to COMIRNATY. In the analysis of unblinded 
follow-up, there were no notable patterns of specific categorie s of serious adverse events that would suggest a 
causal relationship to COMIRNATY. 
 
Adolescents 12 Through 15 Years of Age  
 
In Study 2, 2,260 adolescents (1,131 COMIRNATY; 1,129 placebo) were 12 through 15 years of age. At the 
time of the analysis of the ongoing Study 2 with a data cutoff of September 2, 2021, there were 1,559 
(70.769.0%) adolescents (786 COMIRNATY and 773 placebo) 12 through 15 years of age followed for 
≥4 months after the second dose. The safety evaluation in Study  2 is ongoing. 
 
Demographic characteristics in Study 2 were generally similar w ith regard to age, gender, race, and ethnicity 
among adolescents who received COMIRNATY and those who received  placebo. Overall, among the 
adolescents who received COMIRNATY, 50.1% were male and 49.9% w ere female, 85.8% were White, 4.6% 
were Black or African American, 11.7% were Hispanic/Latino, 6.4 % were Asian, and 0.4% were American 
Indian/Alaska Native.  
 
Local and Systemic Adverse Reactions Solicited in Study 2 
In adolescents 12 through 15 years of age after receiving Dose 2, the mean duration of pain at the injection site 
was 2.5 days (range 1 to 11 days), for redness 1.8 days (range 1 to 5 days), and for swelling 1.6 days (range 1 to 
5 days) in the COMIRNATY group.

Unsolicited Adverse Events 
In Study 2, 2,260 adolescents (1,131 COMIRNATY; 1,129 placebo) were 12 through 15 years of age. Of these, 
634 (56.1%) participants in the COMIRNATY group and 629 (55.7%)  participants in the placebo group had 
follow-up time between ≥4 months to <6 months after Dose 2 in t he blinded placebo-controlled follow-up 
period with an additional 152 (13.4%) and 144 (12.8%) with ≥6 months of blinded follow-up time in the 
COMIRNATY and placebo groups, respectively.  
 
A total of 1,113 (98.4%) participants 12 through 15 years of ag e originally randomized to COMIRNATY had 
≥6 months total (blinded and unblinded) follow-up after Dose 2.    
 
An analysis of all unsolicited adverse events in Study 2 from D ose 1 up to the participant unblinding date was 
conducted. Among participants 12 through 15 years of age who received at least one dose of study vaccine, 
unsolicited adverse events were reported by 95 (8.4%) participa nts in the COMIRNATY group and 
113 (10.0%) participants in the placebo group.

17 A developmental toxicity study has been performed in female rat s administered the equivalent of a single 
human dose of COMIRNATY on 4 occasions ; , twice prior to mating and twice during gestation. These studies  
revealed no evidence of harm to the fetus due to the vaccine (see Animal Data) . 
 
Data 
 
Animal Data 
 In a developmental toxicity study, 0.06 mL of a vaccine formulation containing the same quantity of 
nucleoside-modified messenger ribonucleic acid (mRNA) (30 mcg) and other ingredients included in a single 
human dose of COMIRNATY was administered to female rats by the intramuscular route on 4 occasions: 21 
and 14 days prior to mating, and on gestation days 9 and 20. No  vaccine-related adverse effects on female 
fertility, fetal development, or postnatal development were rep orted in the study.   
 
8.2 Lactation  
 
Risk Summary 
 
It is not known whether COMIRNATY is excreted in human milk. Data are not available to assess the effects of COMIRNATY on the breastfed infant or on milk production/excretion. The developmental and health benefits 
of breastfeeding should be considered along with the mother’s c linical need for COMIRNATY and any 
potential adverse effects on the breastfed child from COMIRNATY  or from the underlying maternal condition. 
For preventive vaccines, the underlying maternal condition is s usceptibility to disease prevented by the vaccine. 
 
8.4 Pediatric Use  Safety and effectiveness of COMIRNATY in individuals 126  through 17 years of age is based on safety and 
effectiveness data in this age group and in adults [see Adverse Reactions (6) and Clinical Studies (14.1)] . 
 The safety and effectiveness of COMIRNATY in individuals younge r than 1 26 years of age have not been 
established. 
 
8.5 Geriatric Use 
 
Of the total number of COMIRNATY recipients in Study 2 as of Ma rch 13, 2021 (N = 22,026), 
20.7% (n = 4,552) were 65 years of age and older and 4.2% (n = 925) were 75 years of age and older  [see 
Clinical Studies (14.1)] . No overall differences in safety or effectiveness were observ ed between these 
recipients and younger recipients.

Efficacy Against COVID-19 
 
The population for the analysis of the protocol pre-specified primary efficacy endpoint included 36,621 participants 12 years of age and older (18,242 in the CO MIRNATY group and 18,379 in the placebo 
group) who did not have evidence of prior infection with SARS-C oV-2 through 7 days after the second dose. 
The population in the protocol pre-specified primary efficacy a nalysis included all participants 12 years of age 
and older who had been enrolled from July 27, 2020, and followe d for the development of COVID-19 through 
November 14, 2020. Participants 18 through 55 years of age and 56 years of age and older began enrollment 
from July 27, 2020, 16 through 17 years of age began enrollment  from September 16, 2020, and 12 through 
15 years of age began enrollment from October 15, 2020.   
For participants without evidence of SARS-CoV-2 infection prior  to 7 days after Dose 2, vaccine efficacy 
against confirmed COVID-19 occurring at least 7 days after Dose  2 was 95.0% (95% credible interval: 90.3, 
97.6), which met the pre-specified success criterion. The case split was 8 COVID-19 cases in the 
COMIRNATY group compared to 162 COVID-19 cases in the placebo g roup.  
 The population for the updated vaccine efficacy analysis includ ed participants 16 years of age and older who 
had been enrolled from July 27, 2020, and followed for the deve lopment of COVID-19 during blinded 
placebo-controlled follow-up through March 13, 2021, representi ng up to 6 months of follow-up after Dose 2. 
There were 12,796 (60.8%) participants in the COMIRNATY group a nd 12,449 (58.7%) in the placebo group 
followed for ≥4 months after Dose 2 in the blinded placebo-cont rolled follow-up period.  
 SARS-CoV-2 variants of concern identified from COVID-19 cases for this age group from this data cutoffin 
this study  include B.1.1.7 (Alpha) and B.1.351 (Beta).  Representation of identified variants among cases in 
vaccine versus placebo recipients did not suggest decreased vac cine effectiveness against these variants. 
 
The updated vaccine efficacy information is presented in Table 57.

Efficacy Against Severe COVID-19 
 
Efficacy analyses of secondary efficacy endpoints supported benefit of COMIRNATY in preventing severe 
COVID-19. Vaccine efficacy against severe COVID-19 is presented  only for participants with or without prior 
SARS-CoV-2 infection (Table 68) as the COVID-19 case counts in participants without prior SAR S-CoV-2 
infection were the same as those in participants with or withou t prior SARS-CoV-2 infection in both the 
COMIRNATY and placebo groups.

In Study 2, an analysis of SARS-CoV-2 50% neutralizing titers ( NT50) 1 month after Dose 2 in a randomly 
selected subset of participants demonstrated non-inferior immune responses (within 1.5-fold) comparing 
adolescents 12 through 15 years of age to participants 16 throu gh 25 years of age who had no serological or 
virological evidence of past SARS-CoV-2 infection up to 1 month  after Dose 2 (Table 10).

16 HOW SUPPLIED/STORAGE AND HANDLING  
 
COMIRNATY Suspension for Intramuscular Injection, multiple dose  vials with gray caps and labels with gray 
borders are supplied in a carton containing 10 multiple dose vi als (NDC 0069-2025-10) or 25 multiple dose 
vials (NDC 0069-2025-25).  
One vial contains 6 doses of 0.3 mL.   
During storage, minimize exposure to room light, and avoid expo sure to direct sunlight and ultraviolet light. 
 
Do not refreeze thawed vials. 
 
Vial Storage Prior to Use 
 
Cartons of COMIRNATY multiple dose vials with gray caps and lab els with gray borders will arrive frozen at 
ultra-cold conditions in thermal containers with dry ice.   
Once received, frozen vials may be immediately transferred to t he refrigerator [2ºC to 8ºC (35ºF to 46ºF)], 
thawed and stored for up to 10 weeks. The 10-week refrigerated expiry date should be recorded on the carton at 
the time of transfer. A carton of 10 vials may take up to 6 hou rs to thaw at this temperature. 
FDA-CBER-2022-5812-0236024
 
24  
Alternatively, frozen vials may be stored in an ultra-low temperature freezer at -90ºC to -60ºC (-130ºF to -76ºF). Do not store vials at -25°C to -15°C (-13°F to 5°F). Once vials  are thawed, they should not be refrozen.  
 If cartons of COMIRNATY multiple dose vials with gray caps and labels with gray borders are received at 2°C 
to 8°C, they should be stored at 2°C to 8°C. Check that the car ton has been updated to reflect the 10-week 
refrigerated expiry date.  Regardless of storage condition, the vaccine should not be used  after the expiration date printed on the vial and 
cartons.  
Vial Storage During Use 
 
If not previously thawed at 2ºC to 8ºC (35ºF to 46ºF), allow vials to thaw at room temperature [up to 25ºC 
(77ºF)] for 30 minutes. 
 COMIRNATY multiple dose vials with gray caps and labels with gr ay borders may be stored at room 
temperature [8°C to 25°C (46°F to 77°F)] for a total of 12 hour s prior to the first puncture. After first puncture, 
the vial should be held between 2 ºC to 25°C (35 °F to 77°F). Vials should be discarded  12 hours after first 
puncture. 
 
DO NOT DILUTE PRIOR TO USE . 
 
Transportation of Vials 
 If local redistribution is needed, vials may be transported at -90°C to -60°C (-130°F to -76°F), or at 2°C to 8°C 
(35°F to 46°F).
