1 INDICATIONS AND USAGE  
 
COMIRNATY is a vaccine indicated for a ctive immunization to prevent coronavirus disease 2019 (COVID-19) 
caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 16 years of age and 
older. 
 
2 DOSAGE AND ADMINISTRATION 
 
For intramuscular injection only. 
 
2.1 Preparation for Administration 
 
Prior to Dilution  
 
• COMIRNATY Multiple Dose Vial contains a volume of 0.45 mL, supplied as a frozen suspension that 
does not contain preservative. Each vial must be thawed and diluted prior to administration.  
• Vials may be thawed in the refrigerator [2ºC to 8ºC (35ºF to 46ºF)] or at room temperature [up to 25ºC (77ºF) ] [see How Supplied/Storage and Handling (16)] . 
• Refer to thawing instructions in the panels below. 
 
Dilution  
 
• Dilute the vial contents using 1.8 mL of sterile 0.9% Sodium Chloride Injection, USP to form COMIRNATY. Do not add more than 1.8 mL of diluent. 
• ONLY use sterile 0.9% Sodium Chloride Injection, USP as the diluent. Do not use bacteriostatic 0.9% 
Sodium Chloride Injection or any other diluent. 
• Vials of ster ile 0.9% Sodium Chloride Injection, USP are provided but shipped separately. Use the 
provided diluent or another  sterile 0.9% Sodium Chloride Injection, USP as the diluent. 
o Provided diluent vials are single-use only; discard after 1.8 mL is withdrawn.  
o If another sterile 0.9% Sodium Chloride Injection, USP is used as the diluent, discard after 1.8 mL is withdrawn.  
o Do not use diluent vials to dilute multiple vials of COMIRNATY.  
• After dilution, 1 vial of COMIRNATY contains 6 doses of 0.3 mL  each .  
• Refer to dilution and dose preparation instructions in the panels below. 
 
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.  
FDA-CBER-2021-5683-0651784
 
3 • 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 . 
 
 • Equalize vial pressure before removing the needle from the vaccine vial by withdrawing 1.8 mL air 
into the empty diluent syringe. 
FDA-CBER-2021-5683-0651785
 
4  
 • Gently invert the vial containing COMIRNATY 
10 times to mix.  
• Do not shake. 
• Inspect the vaccine in the vial.  
• The vaccine will be an off -white suspension. Do not 
use if vaccine is discolored or contains particulate matter.  
 • Record the date and time of dilution on the COMIRNATY vial label.  
• Store between 2°C to 25°C (35°F to 77°F).  
• Discard any unused vaccine 6 hours after dilution. 
 
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.  
 
FDA-CBER-2021-5683-0651786
 
5 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.  
 
A third dose of the COMIRNATY (0.3 mL) administered at least 28 days following the first 2 doses of this 
vaccine is authorized for administration to individuals at least 16 years of age who have undergone solid organ 
transplantation, or who are diagnosed with conditions that are considered to have an equivalent level of 
immunocompromise.  
 
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)]. 
 
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 COMIRNATY.   5.2 Myocarditis and Pericarditis  
 
Postmarketing data demonstrate increased risks of myocarditis and pericarditis, particularly within 7 days following the second dose. The observed risk has been highest in adolescent and young adult males under 40 years of age. Available  data from short- term follow -up suggest that most individuals have had resolution of 
FDA-CBER-2021-5683-0651787
 
6 symptoms. Information is not yet available about potential long-term sequelae. The CDC has published 
considerations for vaccination of individuals with a history of myocarditis or pericarditis  
(https://www.cdc.gov/vaccines/covid- 19/clinical -considerations/myocarditis 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 fainting.  5.4 Altered Immunocompetence  
 Immunocompromised persons, including individuals receiving immunosuppressant 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 w ere 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 w ere 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 site swelling (11.8%), fever (11.5%), and injection 
site redness (10.4%) . 
 
6.1 Clinical Trials Experience  
 
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the 
clinical trials of a vaccine cannot be directly compared to rates 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 years of age and older in 2 clinical studies 
conducted in Germany (Study 1), United States, Argentina, Brazil, Turkey, South Africa, and Germany 
(Study 2). Study BNT162 -01 (Study 1) was a Phase 2-part, dose- escalation trial that enrolled 60  participants , 
18 through 55 years of age and 36 participants, 5 6 through 85 years of age. Study C4591001 (Study 2) is a 
multicenter, multinational, randomized, saline placebo -controlled, observer-blind, dose-finding, vaccine 
candidate-selection and efficacy study that has enrolled approximately 44,047 participants 
(22,026 COMIRNATY; 22,021 placebo) 16 years of age or older  (including 378 and 376 participants  
16 through 17 years of age in the vaccine and placebo groups, respectively). Study 2 also included 200 participants with confirmed stable human immunodeficiency virus (HIV) infection; HIV -positive 
participants are inclu ded 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/mm
3 within 6  months before enrollment, and on stable antiretroviral therapy for at least 6 months.  
 
FDA-CBER-2021-5683-0651788
 
7 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 placebo) 16 years of age and older followed for 
≥4 months after the second dose. 
 
Participants 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 monitored for unsolicited adverse events, including serious adverse events, throughout the study [from Dose 1 through 1 month (all unsolicited adverse events) or 6 months (serious adverse events) after the last vaccination].  Demographic characterist ics in Study 2 were generally similar with regard to age, gender, race, and ethnicity 
among participants who received COMIRNATY and those who received placebo. Overall, among the total participants who received either COMIRNATY or placebo , 50.9% were male , 49.1% were female, 79.3% were 
16 through 64 years of age, 20.7% were 65 years of age and older, 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 reported 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 who were monitored for reactogenicity with an 
electronic diary.  
 
Table 3 and Table 4 present the frequency and severity of reported solicited local and systemic reactions, 
respectively, within 7 days of each dose of COMIRNATY and placebo 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 participants 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.

In participants with chronic, stable HIV infection the frequencies of solicited  local and systemic adverse 
reactions  were similar to or lower than those observed for all participants 16 years of age and older .  
 
In clinical studies, the adverse reactions occurring in <10% of participants 16 through 55 years of age following 
any dose were injection site redness (9.5%), nausea (1.4%), malaise  (0.7%), lymphadenopathy (0.5%) , asthenia 
(0.4%), decreased appetite (0.2%), hyperhidrosis (0.1%), lethargy (0.1%), and night sweats (0.1%).  
 
In clinical studies, the adverse reactions occurring in <10% of participants 56 years of age and older following 
any dose were nausea (1.0%), malaise (0.5%), asthenia (0.3%), lymphadenopathy (0.2%), lethargy (0.2%), 
decreased appetite (0.1%), hyperhidrosis (0.1%), and night sweats (0.1%).  
 
From an independent report (Kamar N, Abravanel F, Marion O, et al. Three doses of an mRNA Covid-19 
vaccine in solid -organ transplant recipients. N Engl J Med) , in 99 individuals who had undergone various solid 
organ transplant procedures (heart, kidney, liver, lung, pancreas) 97±8 months previously who received a third 
vaccine dose, the adverse event profile was similar to that after the second dose and no grade 3 or grade 4 
events were reported  in recipients who were followed for 1 month following post Dose 3. 
 
Unsolicited Adverse Events  
 
Overall 51.1% of participants in the COMIRNATY group and 51.4% of 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 8.1% and 5.9% with ≥6 months of blinded follow -up time in the COMIRNATY and 
placebo groups, respectively.  
 
Upon issuance of the EUA for COMIRNATY, participants were unblinded to offer placebo participants 
COMIRNATY. P articipants were unblinded in a phased manner over a period of months to offer placebo 
participants COMIRNATY. At the time of the updated efficacy analysis 54.5% of participants originally 
randomized to COMIRNATY had ≥6 months of follow -up from Dose 2 and 47.5% of original placebo 
participants had follow- up time between ≥1 month to <2 months after Dose 2 of COMIRNATY. A dverse events 
are reported as incidence rates per 100  person years to account for the variable exposure since unblinding began 
FDA-CBER-2021-5683-0651794
 
13 in a phased manner for participants in the study. Adverse events detailed below for participants 16 years of age 
and older are for the placebo-controlled blinded follow-up period up to the participants’ unblinding dates. 
 
Adverse event s occurred in 28.8% of vaccine recipients who had a follow -up period of at least 6 months after 
Dose 2; 1.6% of the recipients had serious adverse events. 
 
Serious Adverse Events  
 
In Study 2, among participants 16 through 55 years of age who had 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%) at an incidence rate of 2.1 per 100  person
years among  COMIRNATY recipients and 117 (0.9%) 2.4 per 100 person years among  placebo recipients. In a 
similar analysis, in participants 56  years of age and older ( COMIRNATY =8931, placebo = 8895), serious 
adverse events were reported by 165 (1.8%) at an incidence rate of 4.9 per 100 person years among 
COMIRNATY recipients and 151 (1.7%) 4.6 per 100 person years among 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%)at an incidence rate of 6.6 per 100 person years among COMIRNATY recipients and 2 (2 %)6.9 per 100 
person years among placebo recipients.  
 
There were no notable patterns between treatment groups for specific categories of serious adverse events 
(including neurologic, neuro-inflammatory, and thrombotic events) that would suggest a causal relationship to 
COMIRNATY.  
 
Non- Serious Adverse Events  
 
Overall in Study 2 in which 12,995 participants 16 through 55 years of age received COMIRNATY and 
13,026 participants received placebo , all events, which include non-serious adverse events from Dose 1 up to 
the participant unblinding date in ongoing follow-up were reported by 4396 (33.8%) at an incidence rate of 88.4 
per 100 person--years among participants who received COMIRNATY and 2136 (16.4%) 43.5 per 100 person-
years among  participants in the placebo group, for participants who received at least 1 dose. In a similar 
analysis, in participants 56 years of age and older (COMIRNATY = 8931, placebo = 8895), all events, which 
include nonserious adverse events were reported by 2551 (28.6%) at an incidence rate of 75.7 per 100 person-
years among  participants who received COMIRNATY and 1432 (16.1%) 43.3 per 100 person- years among 
participants in the placebo group, for participants who received at least 1  dose. Among participants with 
confirmed stable HIV infection, all events, which include non-serious adverse events from Dose 1 up to the 
participant unblinding date in ongoing follow -up were reported by 29 (29%) at an incidence rate of 95.8 per 100 
person years among participants who received COMIRNATY and 15 (15%) 52.0 per 100 person years among 
participants in the placebo group, for participants who received at least 1 dose. 
 
In these analyses, 58.2% of study participants had at least 4 months of follow-up after Dose 2. The higher 
frequency of reported unsolicited non- serious adverse events among COMIRNATY recipients (inclusive of 
stable HIV infection) compared to placebo recipients was primarily attributed to local and systemic adverse 
FDA-CBER-2021-5683-0651795
 
14 events reported during the first 7 days following each dose of vaccine that are consistent with adverse reactions 
solicite d among participants in the reactogenicity subset and presented in Table  3 and Table 4.  
 
From Dose 1 up to the participant unblinding date, reports of lymphadenopathy were imbalanced with notably 
more cases in the COMIRNATY group (87) v ersus the placebo g roup ( 8). 
 
Throughout the placebo-controlled safety follow-up period to date, 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. Currently available information is insufficient to 
determine a causal relationship with the vaccine. 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. 
 
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, p ericarditis  
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  
 
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 administered 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 four 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 ). 
 
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/ . 
 
FDA-CBER-2021-5683-0651796
 
15 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 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 preve nted by the vaccine.  
 
8.4 Pediatric Use  
 Safety and effectiveness of COMIRNATY in individuals 16 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 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 = 4552) 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.  
 
8.6 Immunocompromised Use  
 
From an independent report (Kamar N, Abravanel F, Marion O, et al. Three doses of an mRNA Covid-19 
vaccine in solid -organ transplant recipients. N Engl J Med) , safety and effectiveness of a third dose of 
COMIRNATY have been evaluated  in persons that received solid organ transplants. The administration of a 
third dose of vaccine appears to be only moderately effective in increasing  potentially protective antibody titers. 
Patients should still be counselled to maintain physical precautions to help prevent COVID-19. In addition, 
close contacts of immunocompromised persons should be vaccinated as appropriate for their health status .

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/m2], respectively. The mean age at 
vaccination was 4 98.83 or 4 98.72  years and median age was 5 10.0 or 510.0 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 COMIRNATY 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.

Note: Confirmed cases were determined by Reverse Transcription Polymerase Chain Reaction (RT PCR) and 
at least 1 symptom consistent with COVID 19 (symptoms included: fever; new or increased cough; new or 
increased shortness of breath; chills; new or increased muscle pain; new loss of taste or smell; sore throat; 
diarrhea; vomiting). 
* Participants who had no evidence of past SARS CoV 2 infection (i.e., N binding antibody [serum] 
negative at Visit 1 and SARS CoV 2 not detected by NAAT [nasal swab] at Visits 1 and 2), and had negative 
NAAT (nasal swab) at any unscheduled visit prior to 7 days after Dose 2 were included in the a nalysis.  
a. N = Number of participants in the specified group.  
b. n1 = Number of participants meeting the endpoint definition. 
c. Total surveillance time in 1000 person years for the given endpoint across all participants within each 
group at risk for the endpoint. Time period for COVID 19 case accrual is from 7 days after Dose 2 to the end 
of the surveillance period. 
d. n2 = Number of participants at risk for the endpoint. 
e. No confirmed cases were identified in participants 12 to 15 years of age. 
f. Two-sided credible interval for vaccine efficacy was calculated using a beta- binomial model with a 
beta (0.700102, 1) prior for θ=r(1 -VE)/(1+r(1 -VE)), where r is the ratio of surveillance time in the active 
vaccine group over that in the placebo group. 
g. Two-sided confidence interval (CI) for vaccine efficacy is derived based on the Clopper and Pearson 
method adjusted to the surveillance time.  
 
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%. The case split was 8 COVID -19 
cases in the BNT162b2 group compared to 162 COVID- 19 cases in the placebo group. The 95% credible 
interval for the vaccine efficacy was 90.3% to 97.6%, i ndicating that the true vaccine efficacy  is at least 90.3% 
with a 97.5% probability, which met the pre -specified success criterion.  
 
The population for the updated vaccine efficacy analysis included participants 16 years of age and older who 
had been en rolled from July 27, 2020, and followed for the development of COVID-19 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 placebo group 
followed for ≥4 months after Dose 2 in the blinded placebo-controlled follow-up period.

Immunogenicity in Solid Organ Transplant Recipients  
 
From an independent report (Kamar N, Abravanel F, Marion O, et al. Three doses of an mRNA Covid-19 
vaccine in solid -organ transplant recipients. N Engl J Med) , a single arm study has been conducted in 
FDA-CBER-2021-5683-0651802
 
21 101 individuals who had undergone various solid organ transplant procedures (heart, kidney, liver, lung, 
pancreas) 97±8 months previously. A third dose of COMIRNATY was administered to 99 of these individuals 
approximately 2 months after they had received a second dose. Among the 59 patients who had been 
seronegative before the third dose, 26 (44%) were seropositive at 4 weeks after the third dose. All 40 patients 
who had been seropositive before the third dose were still seropositive 4 weeks later. The prevalence of 
anti-SARS -CoV- 2 antibodies was 68% (67 of 99 patients) 4 weeks after th e third dose. 
 
16 HOW SUPPLIED/STORAGE AND HANDLING  
 
COMIRNATY Suspension for Intramuscular Injection, Multiple Dose Vials are supplied in a carton containing 
25 multiple dose vials (NDC 0069-1000-03) or 195 multiple dose vials (NDC 0069-1000-02). A 0.9% Sodium Chloride Injection, USP diluent is provided but shipped separately , and should be stored at controlled room 
temperature 20 °C to 25°C (68°F to 77°F) [see USP Controlled Room Temperature]. The provided 0.9% Sodium 
Chloride Injection, USP diluent will be  supplied either as cartons of 10 mL single- use vial s manufactured by 
Hospira, Inc (NDC  0409-4888-10), or 2 mL single- use vial s manufactured by Fresenius Kabi USA, LLC 
(NDC  63323-186-02). 
 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 immediately from the thermal container and preferably store in an ultra- low temperature freezer 
between - 8090 ºC to -60ºC (- 112ºF 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 - 8090ºC to -60ºC (- 112ºF 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 t o 5°F) may be returned 1 time to  the recommended storage 
condition of - 8090ºC to -60ºC (- 112ºF 130ºF to -76ºF). 
 
 
FDA-CBER-2021-5683-0651803
 
22 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.  
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.
