Reference is made to the Request for Comments and Advice submit ted 04 February 2021 
regarding Pfizer/BioNTech’s proposal for the clinical and post-a uthorization safety data 
package for the Biologics License Application (BLA) for our inve stigational COVID-19 
Vaccine (BNT162b2). Further reference is made to the Agency’s 0 9 March 2021 response to 
this request, and specifically, the following request from the Agency.
“Monthly safety reports primarily focus on events that occurred during the reporting interval 
and include information not relevant to a BLA submission such as line lists of adverse events by country. We are most interested in a cumulative analysis of post-authorization safety data to support your future BLA submission. Please submit an integrated analysis of your cumulative post-authorization safety data, including U.S. and foreign post-authorization experience, in your upcoming BLA submission. Please include a cumulative analysis of the Important Identified Risks, Important Potential Risks, and areas of Important Missing Information identified in your Pharmacovigilance Plan, as well as adverse events of special interest and vaccine administration errors (whether or not associated with an adverse event). Please also include distribution data and an analysis of the most common adverse events. In addition, please submit your updated Pharmacovigilance Plan with your BLA submission.”
This document provides an integrated analysis of the cumulative  post-authorization safety 
data, including U.S. and foreign post-authorization adverse eve nt reports received through 28 
February 2021.2. METHODOLOGY
Pfizer is responsible for the management post-authorization saf ety data on behalf of the 
MAH BioNTech according to the Pharmacovigilance Agreement in place. Data from 
BioNTech are included in the report when applicable.
Pfizer’s safety database contains cases of AEs reported spontan eously to Pfizer, cases 
reported by the health authorities, cases published in the medi cal literature, cases from 
Pfizer-sponsored marketing programs, non-interventional studies , and cases of serious AEs 
reported from clinical studies regardless of causality assessme nt.
The limitations of post-marketing adverse drug event reporting should be considered when 
interpreting these data:
•Reports are submitted voluntarily, and the magnitude of underre porting is unknown. 
Some of the factors that may influence whether an event is reported include: length of 
time since marketing, market share of the drug, publicity about  a drug or an AE, 
seriousness of the reaction, regulatory actions, awareness by h ealth professionals and 
consumers of adverse drug event reporting, and litigation.
•Because many external factors influence whether or not an AE is  reported, the 
spontaneous reporting system yields reporting proportions not i ncidence rates. As a 
result, it is generally not appropriate to make between-drug co mparisons using these 090177e196ea1800\A pproved\A pproved On: 30-A pr-2021 09:26 (GMT )

Page 6proportions; the spontaneous reporting system should be used for signal detection 
rather than hypothesis testing. 
•In some reports, clinical information (such as medical history,  validation of diagnosis, 
time from drug use to onset of illness, dose, and use of concom itant drugs) is missing 
or incomplete, and follow-up information may not be available. 
•An accumulation of adverse event reports (AERs) does not necess arily indicate that a 
particular AE was caused by the drug; rather, the event may be due to an underlying 
disease or some other factor(s) such as past medical history or  concomitant 
medication.
•Among adverse event reports received into the Pfizer safety dat abase during the 
cumulative period, only those having a complete workflow cycle in the safety database 
(meaning they progressed to Distribution or Closed workflow sta tus) are included in the 
monthly SMSR. This approach prevents the inclusion of cases tha t are not fully processed 
hence not accurately reflecting final information. Due to the l arge numbers of 
spontaneous adverse event reports received for the product, the M AH has prioritised the 
processing of serious cases, in order to meet expedited regulatory reporting timelines and ensure these reports are available for signal detection and eva luation activity. The 
increased volume of reports has not impacted case processing fo r serious reports, and 
compliance metrics continue to be monitored weekly with prompt action taken as needed 
to maintain compliance with expedited reporting obligations. No n-serious cases are 
entered into the safety database no later than 4 calendar days from receipt. Entrance into the database includes the coding of all adverse events; this all ow for a manual review of 
events being received but may not include immediate case proces sing to completion. 
Non-serious cases are processed as soon as possible and no late r than 90 days from 
receipt.  Pfizer has also taken a multiple actions to help allev iate the large increase of 
adverse event reports. This includes significant technology enha ncements, and process 
and workflow solutions, as well as increasing the number of dat a entry and case 
processing colleagues. To date, Pfizer has onboarded approximat ely  additional full-
time employees (FTEs). More are joining each month with an expe cted total of more than 
 additional resources by the end of June 2021.

Anaphylaxis Since the first temporary authorization for emergenc y supply under Regulation 174 in the UK 
(01 December 2020) and through 28 February 2021, 1833 potentially relevant cases were retrieved from 
the Anaphylactic reaction SMQ (Narrow and Broad) search strateg y, applying the MedDRA algorithm. 
These cases were individually reviewed and assessed according to Brighton Collaboration (BC) 
definition and level of diagnostic certainty as shown in the Table below:
Brighton Collaboration Level Number of cases
BC 1 290
BC 2 311
BC 3 10
BC 4 391
BC 5 831
Total 1833
Level 1 indicates a case with the highest level of diagnostic certainty of anaphylaxis, 
whereas the diagnostic certainty is lowest for Level 3. Level 4 is defined as “reported 
event of anaphylaxis with insufficient evidence to meet the cas e definition” and Level 
5 as not a case of anaphylaxis.
There were 1002 cases (54.0% of the potentially relevant cases retrieved), 2958 potentially relevant events, from the Anaphylactic reaction SMQ (Broad and Narrow) search strategy, meeting BC Level 1 to 
4:  
Country of incidence: UK (261), US (184), Mexico (99), Italy (82), Germany (67), Spain (38), France 
(36), Portugal (22), Denmark (20), Finland, Greece (19 each), S weden (17), Czech Republic , 
Netherlands (16 each), Belgium, Ireland (13 each), Poland (12),  Austria (11); the remaining 57 cases 
originated from 15 different countries.
Relevant event seriousness: Serious (2341), Non-Serious (617);
Gender: Females (876), Males (106), Unknown (20);
Age (n=961) ranged from 16 to 98 years (mean = 54.8 years, medi an = 42.5 years);

Conclusion: Evaluation of BC cases Level 1 - 4 did not reveal any significant new safety information. 
Anaphylaxis is appropriately described in the product labeling as are non-anaphylactic hypersensitivity 
events. Surveillance will continue.
a Different clinical outcome may be reported for an event that o ccurred more than once to the same individual.
b There were 4 individuals in the anaphylaxis evaluation who die d on the same day they were vaccinated. 
Although these patients experienced adverse events (9) that are potential symptoms of anaphylaxis, they all had serious underlying medical conditions, and one individual appeared to a lso have COVID-19 pneumonia, that likely contributed to 
their deaths090177e196ea1800\A pproved\A pproved On: 30-A pr-2021 09:26 (GMT )

Vaccine-
Associated Enhanced Disease 
(VAED), 
including Vaccine-Associated 
Enhanced 
Respiratory Disease (VAERD)No post-authorized AE reports have been identified as cases of VAED/VAERD, therefore, there is no 
observed data at this time.  An expected rate of VAED is difficult to establish so a meaningful observed/expected analysis cannot be conducted at this point based on available data.  The feasibility of conducting such an analysis will be re-evaluated on an ongoing basis as data on the virus grows and the 
vaccine safety data continues to accrue. 
The search criteria utilised to identify potential cases of VAE D for this report includes PTs indicating a 
lack of effect of the vaccine and  PTs potentially indicative o f severe or atypical COVID-19
a.
Since the first temporary authorization for emergency supply under Regulation 174 in the UK (01 
December 2020) and through 28 February 2021, 138 cases [0.33% of the total PM dataset], reporting 317 potentially relevant events were retrieved:
Country of incidence: UK (71), US (25), Germany (14), France, Italy, Mexico, Spain, (4 each), Denmark 
(3); the remaining 9 cases originated from 9 different countrie s;
Cases Seriousness: 138;
Seriousness criteria for the total 138 cases: Medically signifi cant (71, of which 8 also serious for 
disability), Hospitalization required (non-fatal/non-life threatening) (16, of which 1 also serious for 
disability), Life threatening (13, of which 7 were also serious for hospitalization), Death (38).Gender: Females (73), Males (57), Unknown (8);
Age (n=132) ranged from 21 to 100 years (mean = 57.2 years, med ian = 59.5);
Case outcome: fatal (38), resolved/resolving (26), not resolved  (65), resolved with sequelae (1), unknown 
(8);
Of the 317 relevant events, the most frequently reported PTs (≥2%) were: Drug ineffective (135), 
Dyspnoea (53), Diarrhoea (30), COVID-19 pneumonia (23), Vomitin g (20), Respiratory failure (8), and 
Seizure (7).
Conclusion: VAED may present as severe or unusual clinical manif estations of COVID-19. Overall, there 
were 37 subjects with suspected COVID-19 and 101 subjects with c onfirmed COVID-19 following one 
or both doses of the vaccine; 75 of the 101 cases were severe, resulting in hospitalisation, disability, 
life-threatening consequences or death. None of the 75 cases co uld be definitively considered as 
VAED/VAERD.In this review of subjects with COVID-19 following vaccination, based on the current evidence, 
VAED/VAERD remains a theoretical risk for the vaccine. Surveillance will continue.

compared with the non-paediatric population.
Vaccine EffectivenessCompany conventions for coding cases indicative of lack of efficacy:
The coding conventions for lack of efficacy in the context of a dministration of the COVID-19 vaccine
were revised on 15 February 2021, as shown below: 
• PT “Vaccination failure” is coded when ALL of the following criteria are met:
o The subject has received the series of two doses per the dosing regimen in local 
labeling.
o At least 7 days have elapsed since the second dose of vaccine h as been administered.
o The subject experiences SARS-CoV-2 infection (confirmed laborat ory tests).
• PT “Drug ineffective” is coded when either of the following applies: 
o The infection is not confirmed as SARS-CoV-2 through laboratory  tests 
(irrespective of the vaccination schedule). This includes scena rios where LOE is 
stated or implied, e.g., “the vaccine did not work”, “I got COV ID-19”.
o It is unknown:
ƒ Whether the subject has received the series of two doses per th e dosing 
regimen in local labeling;
ƒ How many days have passed since the first dose (including unspecified number of days like” a few days”, “some days”, etc.);
ƒ If 7 days have passed since the second dose;
o The subject experiences a vaccine preventable illness 14 days after receiving the 
first dose up to and through 6 days after receipt of the second dose.
Note: after the immune system as had sufficient time (14 days) to respond to the vaccine, a report of 
COVID-19 is considered a potential lack of efficacy even if the vaccination course is not complete.

Vaccination failure cases (16)
• Vaccination failure seriousness: all serious;
• Lack of efficacy term was reported in all cases after the 2nd dose:
• Latency of lack of efficacy was known for 14 cases:
o Within 7 and 13 days: 8 subjects;
o Within 15 and 29 days: 6 subjects.
COVID-19 (10) and Asymptomatic COVID-19 (6) were the reported vaccine preventable infections that 
occurred in these 16 cases.
Conclusion: No new safety signals of vaccine lack of efficacy h ave emerged based on a review of these 
cases.
a. From a total of 417 cases, 4 cases were excluded from the analysis. In 3 cases, the MAH was informed 
that a 33-year-old and two unspecified age pregnant female pati ents were scheduled to receive bnt162b2 (PT 
reported Off label use and Product use issue in 2 cases; Circumstance or information capable of leading to medication error in one case). One case reported the PT Morning  sickness; however, pregnancy was not 
confirmed in this case. b. 558 additional cases retrieved in this dataset were excluded f rom the analysis; upon review, 546 cases 
cannot be considered true lack of efficacy cases because the PT  Drug ineffective was coded but the subjects 
developed SARS-CoV-2 infection during the early days from the f irst dose (days 1 – 13); the vaccine has not 
had sufficient time to stimulate the immune system and, consequently, the development of a vaccine preventable disease during this time is not considered a potential lack of effect of the vaccine; in 5 cases the 
PT Drug ineffective was removed after data lock point (DLP) bec ause the subjects did not develop COVID-
19 infection; in 1 case, reporting Treatment failure and Transi ent ischaemic attack, the Lack of efficacy PT 
did not refer to BNT162b2 vaccine; 5 cases have been invalidated in the safety database after DLP; 1 case 
has been deleted from the discussion because the PTs reported Pat hogen resistance and Product preparation 
issue were not indicative of a lack of efficacy. to be eliminated. c. Upon review, 31 additional cases were excluded from the analysis as the data reported (e.g. clinical 
details, height, weight, etc.) were not consistent with paediatric subjects
d. Upon review, 28 additional cases were excluded from the analy sis as the data reported (e.g. clinical 
details, height, weight, etc.) were not consistent with paediat ric subjects.
e. Different clinical outcomes may be reported for an event that occurred more than once to the same individual
f. In 2 cases the PT Vaccination failure was replaced with Drug i neffective after DLP. Another case was 
not included in the discussion of the Vaccination failure cases  because correct schedu ling (21 days apart 
between the first and second dose) cannot be confirmed.090177e196ea1800\A pproved\A pproved On: 30-A pr-2021 09:26 (GMT )

Page 163.1.3. Review of Adverse Events of Special Interest (AESIs)
Please refer to Appendix 1 for the list of the company’s AESIs for BNT162b2.
The company’s AESI list takes into consideration the lists of A ESIs from the following 
expert groups and regulatory authorities: Brighton Collaboratio n (SPEAC), ACCESS 
protocol, US CDC (preliminary list of AESI for VAERS surveillan ce), MHRA (unpublished 
guideline). 
The AESI terms are incorporated into a TME list and include events of interest due to their 
association with severe COVID-19 and events of interest for vacc ines in general. 
The AESI list is comprised of MedDRA PTs, HLTs, HLGTs or MedDRA SM Qs and can be 
changed as appropriate based on the evolving safety profile of t he vaccine.
Table 7 provides a summary review of cumulative cases within AESI categories in the Pfizer safety database. This is distinct from safety signal evaluations which are conducted and included, as appropriate, in the Summary Monthly Safety Reports  submitted regularly to the 
FDA and other Health Authorities.

4. DISCUSSION
Pfizer performs frequent and rigorous signal detection on BNT162b2 cases.  The findings of 
these signal detection analyses are consistent with the known s afety profile of the vaccine.  
This cumulative analysis to support the Biologics License Appli cation for BNT162b2, is an 
integrated analysis of post-authorization safety data, from U.S . and foreign experience, 
focused on Important Identified Risks, Important Potential Risks, and areas of Important 
Missing Information identified in the Pharmacovigilance Plan, as well as adverse events of special interest and vaccine administration errors (whether or not associated with an adverse event). The data do not reveal any novel safety concerns or risks requiring label changes and support a favorable benefit risk profile of to the BNT162b2 vacc ine.090177e196ea1800\A pproved\A pproved On: 30-A pr-2021 09:26 (GMT )
