3 THAWING PRIOR TO DILUTION  
 • Thaw vial(s) of COMIRNATY  before dilution either 
by: 
o Allowing vial(s) to thaw in the refrigerator [2ºC 
to 8ºC (35ºF to 46ºF)]. A carton of vials may take up to 3 hours to thaw, and thawed vials can be stored in the refrigerator for up to 1 month.  
o Allowing vial(s) to sit at room temperature [up to 25ºC (77ºF)] for 30 minutes. 
• Using either thawing method, vials must reach room temperature before dilution and must be diluted 
within 2 hours.  
 
 • Before dilution invert vaccine vial gently 10 times.  
• Do not shake.  
• Inspect the liquid in the vaccine vial prior to dilution. The liquid is a white to off- white 
suspension and may contain white to off- white 
opaque amorphous particles. 
• Do not use if liquid is discolored or if other particles are observed. 
DILUTION 
 
 • ONLY use sterile 0.9% Sodium Chloride Injection, USP as the diluent. 
• Withdraw 1.8 mL of diluent into a transfer syringe 
(21-gauge or narrower needle). 
• Add 1.8 mL of sterile 0.9% Sodium Chloride 
Injection, USP into the vaccine vial .

5 PREPARATION OF INDIVIDUAL 0.3  mL DOSES OF COMIRNATY 
 
 • Withdraw 0.3 mL  of COMIRNATY preferentially 
using low dead-volume syringes and/or needles. 
• Each dose must contain 0.3 mL of vaccine.  
• If the amount of vaccine remaining in a single vial 
cannot provide a full dose of 0.3 mL, discard the 
vial and any excess volume.  
• Administer immediately.  
 After dilution, vials of COMIRNATY contain 6 doses of 0.3 mL of vaccine. Low dead -volume syringes and/or 
needles can be used to extract 6 doses from a single vial. If standard syringes and needles are used, there may not be sufficient volume to extract a sixth dose 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.  
 
2.2 Administration Information  
 Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. The vaccine will be an off -white suspension. Do not 
administer if vaccine is discolored or contains particulate matter.  
 Administer a single 0.3 mL dose of COMIRNATY intramuscularly.  2.3 Vaccination Schedule  
 COMIRNATY is administered intramuscularly as a series of 2 doses (0.3 mL each) 3 weeks apart.  
 There are no data available on the interchangeability of COMIRNATY with other COVID -19 vaccines to complete 
the vaccination series.  Individuals who 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. After preparation, a single dose is 0.3 mL.  
 
4 CONTRAINDICATIONS  
 
Do not administer COMIRNATY to individuals with known history of a severe allergic reaction (e.g., anaphylaxis) to any component of the COMIRNATY [s ee Description (1 1)].

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, respectively.  
 
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 following any dose, through 1 month after Dose 2, in 
participants 16 years of age and older (N=43,847; 21,926 COMIRNATY group vs. 21,921 placebo group), 
those assessed as adverse reactions not already cap tured 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 Dose 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 one dose of study vaccine, 12,995 of whom  received  COMIRNATY and 
13,026 of whom received placebo , unsolicited adverse events  were reported by 4,396 (33.8%)  participants in 
the COMIRNATY group and 2,136 (16.4%)  participants in the pla cebo group. In a similar analysis in

17 6.2 Postmarketing Experience  
 
The following adverse reactions have been identified during postmarketing use of COMIRNATY, including 
under Emergency Use Authorization. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.  
 Cardiac Disorders: myocarditis, pericarditis  
Gastrointestinal Disorders: diarrhea, vomiting  
Immune System Disorders: severe allergic reactions, including anaphylaxis , and other hypersensitivity reactions 
(e.g., rash, pruritus, urticaria, angioedema)  
Musculoskeletal and Connective Tissue Disorders: pain in extremity (arm) 
 
8 USE IN SPECIFIC POPULATIONS  
 
8.1 Pregnancy  
 
There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to COMIRNATY during pregnancy. Women who are vaccinated with COMIRNATY during pregnancy are encouraged to enroll in the registry by visiting https://mothertobaby.org/ongoing-study/covid19- vaccines/
. 
 
Risk Summary   
 All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the US 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 COMIRNATY administe red to pregnant women are 
insufficient to inform vaccine-associated risks in pregnancy.   A developmental toxicity stud y has been performed in female rats 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 reported 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 clinical need for COMIRNATY and any 
FDA-CBER-2022-5812-0220485
 
18 potential adverse effects on the breastfed child from COMIRNATY or from the underlying maternal condition. 
For preventive vaccines, the underlying maternal condition is susceptibility to disease prevented by the vaccine.  
8.4 Pediatric Use  
 
Safety and effectiveness of COMIRNATY in individuals 16 12 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 younger than 16 12 years of age have not been 
established.  
 
8.5 Geriatric Use  
 
Of the total number of COMIRNATY recipients in Study 2 as of March 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 observed between these 
recipients  and younger recipients.  
 
11 DESCRIPTION  
 
COMIRNATY (COVID -19 V accine, mRNA) is a sterile suspension for injection for intramuscular use. 
COMIRNATY is supplied as a frozen suspension in multiple dose vials; each vial must be diluted with 1.8 mL of sterile 0.9% Sodium Chloride Injection, USP prior to use to form the vaccine.  Each dose of COMIRNATY 
contains 30 mcg of a nucleoside- modified messenger RNA ( mRNA) encoding the viral spike (S) glycoprotein 
of SARS -CoV-2.  
 Each 0.3 mL dose of the COMIRNATY also includes the following ingredients: lipids (0.43 mg 
((4-hydroxybutyl)azanediyl)bis(hexane-6,1- diyl)bis(2 -hexyldecanoate), 0.05 mg 2-(polyethylene 
glycol 2000)- N,N-ditetradecylacetamide, 0.09 mg 1,2-distearoyl- sn-glycero-3-phosphocholine, and 0.2 mg 
cholesterol), 0.01 mg potassium chloride, 0.01 mg monobasic potassium phosphate, 0.36 mg sodium chloride, 0.07 mg dibasic sodium phosphate dihydrate, and 6 mg sucrose. The diluent (0.9% Sodium Chloride Injection, USP) contributes an additional 2.16 mg sodium chloride per dose. 
 COMIRNATY does not contain preservative.   The vial stoppers are not made with natural rubber latex.  
 
12 CLINICAL PHARMACOLOGY 
 
12.1 Mechanism of Action  
 
The nucleoside-modified m RNA in COMIRNATY is formulated in lipid particles, which enable delivery of the 
mRNA into host cells to allow expression of the SARS-CoV-2 S antigen. The vaccine elicits an immune response to the S antigen, which protects against COVID-19. 
 
FDA-CBER-2022-5812-0220486
 
19 13 NONCLINICAL TOXICOLOGY  
 
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility  
 
COMIRNATY has not been evaluated for the potential to cause carcinogenicity, genotoxicity, or impairment of 
male fertility. In a developmental toxicity study  in rats with COMIRNATY t here were no vaccine- related 
effects on female fertility [see Use in Specific  Populations (8.1)] . 
 
14 CLINICAL STUDIES  
 
14.1 Efficacy in Participants 16 Years of Age and Older  
 
Study 2 is a n ongoing, multicenter, multinational, randomized, placebo-controlled, observer-blind, dose-finding, 
vaccine candidate–selection, and efficacy study in participants 12 years of age and older. Randomization was stratified by age: 12 through 15 years of age, 16 through 55 years of age, or 56 years of age and older, with a minimum of 40% of participants in the ≥56-year stratum. The study excluded participants who were immunocompromised and those who had previous  clinical or microbiological diagnosis of COVID19. 
Particip ants with preexisting stable disease, defined as disease not requiring significant change in therapy or 
hospitalization for worsening disease during the 6 weeks- before enrollment, were included as were participants with known stable infection with HIV, he patitis C virus (HCV), or hepatitis B virus (HBV).  
 
In Study 2, based on data accrued through March 13, 2021, approximately 44,000 participants 1612 years of age 
and older were randomized equally and received 2 doses of COMIRNATY or placebo. Participants are planned to be followed for up to 24 months, for assessments of safety and efficacy against COVID-19.  
 Overall, among the total participants who received COMIRNATY or placebo, 51.4% or 50.3% were male and 48.6% or 49.7% were female, 79.1% or 79.2% were 16 through 64 years of age, 20.9% or 20.8% were 65 years 
of age and older, 81.9% or 82.1% were White, 9.5% or 9.6% were Black or African American, 1.0 % or 0.9% 
were American Indian or Alaska Native, 4. 4% or 4.3% were Asian, 0.3% or 0.2% Native Hawaiian or other 
Pacific Islander, 2 5.6% or 2 5.4% were Hispanic/Latino, 73.9% or 74.1% were non- Hispanic/Latino, 0.5% or 
0.5% did not report ethnicity, 46.0% or 45.7% had comorbidities [participants who have 1 or more comorbidities that increase the risk of severe COVID -19 disease: defined as subjects who had at least one of the 
Charlson comorbidity index category or body mass index (BMI) ≥30 kg/m
2], respectively. The mean age at 
vaccination was 4 9.8 or 4 9.7 years and median age was 5 1.0 or 51.0 in participants who received 
COMIRNATY or placebo, respectively.  
 
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 C OMIRNATY group and 18,379 in the placebo 
group) who did not have evidence of prior infection with SARS-CoV-2 through 7 days after the second dose. The population in the protocol pre- specified primary efficacy analysis included all participants 12 years of age 
and older who had been enrolled from July 27, 2020, and followed 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 C OVID- 19 occurring at least 7 days after Dose 2 was 95.0%  (95% credible interval: 90.3, 
FDA-CBER-2022-5812-0220487
 
20 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 group.  
 The population for the updated vaccine efficacy analysis included participants 16 years of age and older who had been enrolled from July 27, 2020, and  followed for the development of COVID19 during blinded 
placebo -controlled follow-up through March 13, 2021, representing up to 6 months of follow-up after Dose 2. 
There were 12,796 (60.8%)  participants  in the COMIRNATY group and 12,449 ( 58.7%) in the plac ebo group 
followed for ≥4 months after Dose 2 in the blinded placebo-controlled follow-up period.  
 SARS -CoV-2 variants of concern identified from COVID-19 cases in 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 vaccine effectiveness against these variants.  
 
The updated vaccine efficacy information is presented in Table 57.

Efficacy Against S evere 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 SARS-CoV-2 
infection were the same as those in participants with or without prior SARS-CoV-2 infection in both the COMIRNATY and placebo groups.

24  
After dilution, 1 vial contains 6 doses of 0.3 mL.  
 During storage, minimize exposure to room light, and avoid exposure to direct sunlight and ultraviolet light.  Do not refreeze thawed vials.  
 
Frozen Vials Prior to Use  
 Cartons of COMIRNATY Multiple Dose Vials arrive in thermal containers with dry ice. Once received, remove the vial cartons i mmediately from the thermal container and preferably store in an ultra- low temperature freezer 
between -90ºC to -60ºC (-130ºF to -76ºF) until the expiry date printed on the label. Alternatively, vials may be stored at -25°C to - 15°C ( -13°F to 5°F) for up to 2 weeks . Vials must be kept frozen and protected from light, in 
the original cartons, until ready to use. Vials stored at -25°C to -15 °C (-13°F to 5°F) for up to 2 weeks may be 
returned 1 time to  the recommended storage condition of -90ºC to -60ºC (-130ºF to -76ºF). Total cumulative 
time the vials are stored at -25°C to - 15°C ( -13°F to 5°F) should be tracked and should not exceed 2 weeks . 
 
If an ultra -low temperature freezer is not available, the thermal container in which COMIRNATY arrives may 
be used as temporary  storage when consistently re-filled to the top of the container with dry ice. Refer to the 
re-icing guidelines packed in the original thermal container for instructions regarding the use of the thermal 
container for temporary storage. The thermal container maintains a temperature range of -90ºC to -60ºC (-130ºF 
to -76ºF). Storage of the vials between -96°C to - 60°C ( -141°F to -76°F) is not considered an excursion from 
the recommended storage condition.  
 
Transportation of Frozen Vials  
 If local redistribution is needed and full cartons containing vials cannot be transported at -90°C to -60°C (-130°F to -76°F), vials may be transported at -25°C to - 15°C ( -13°F to 5°F). Any hours used for transport 
at -25°C to - 15°C ( -13°F to 5°F) count against the 2- week limit for storage at -25°C to - 15°C ( -13°F to 5°F). 
Frozen vials transported at -25°C to - 15°C ( -13°F to 5°F) may be returned 1 time to  the recommended storage 
condition of -90ºC to -60ºC (-130ºF to -76ºF).  
Thawed Vials Before Dilution  
 Thawed Under Refrigeration  
 Thaw and then store undiluted vials in the refrigerator [2ºC to 8ºC (35ºF to 46ºF)] for up to 1 month. A carton of 25 vials or 195 vials may take up to 2 or 3 hours , respectively,  to thaw in the refrigerator, whereas a fewer 
number of vials will thaw in less time.   Thawed at Room Temperature  For immediate use, thaw  undiluted vials at room temperature [up to 25ºC (77ºF)] for 30 minutes.  Thawed vials 
can be handled in room light conditions.   Vials must reach room temperature before dilution.  
 Undiluted vials may be stored at room temperature for no more than 2 hours.  
FDA-CBER-2022-5812-0220492
 
25 Transportation of Thawed  Vials  
 
Available data support transportation of 1 or more thawed vials at 2°C to 8°C (35°F to 46°F) for up to 12 hours.   
Vials After Dilution  
 After dilution, store  vials between 2°C  to 25°C (35°F to 77°F) and use within 6 hours from the time of dilution. 
During storage, minimize exposure to room light, and avoid exposure to direct sunlight and ultraviolet light. Any vaccine remaining in vials must be discarded after 6  hours. Do not refreeze.
