NEW YORK AND MAINZ, GERMANY, May 13, 2022 — Pfizer Inc. (NYSE: PFE, “Pfizer”) and BioNTech SE (Nasdaq: BNTX, “BioNTech”) today announced they have reached an agreement with the European Commission (EC) to amend their originally agreed contractual delivery schedules for the Pfizer-BioNTech COVID-19 Vaccine. This amendment rephases planned deliveries to help support the European Commission and Member States' ongoing immunization programs, and is aligned to the companies’ commitment to working collaboratively to identify pragmatic solutions to address the evolving pandemic needs. Doses scheduled for delivery in June through August 2022, will now be delivered in September through fourth quarter 2022. This change of delivery schedule does not impact the companies’ full-year 2022 revenue guidance or the full-year commitment of doses to be delivered to EC Member States in 2022.

Pfizer and BioNTech continue to evaluate potential adapted vaccines, including variant-based vaccines, and expect to share these data in the coming months.

have had myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining outside the heart)
have a fever
have a bleeding disorder or are on a blood thinner
are immunocompromised or are on a medicine that affects the immune system
are pregnant, plan to become pregnant, or are breastfeeding
have received another COVID-19 vaccine
have ever fainted in association with an injection
• Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY® (COVID-19 Vaccine, mRNA) may not protect all vaccine recipients

• You should not receive Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY® (COVID-19 Vaccine, mRNA) if you have had a severe allergic reaction to any of its ingredients or had a severe allergic reaction to a previous dose of Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY®

• There is a remote chance that Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY® (COVID-19 Vaccine, mRNA) could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose of the vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received the vaccine for monitoring after vaccination. If you experience a severe allergic reaction, call 9-1-1 or go to the nearest hospital

Seek medical attention right away if you have any of the following symptoms:

difficulty breathing, swelling of the face and throat, a fast heartbeat, a bad rash all over the body, dizziness, and weakness
• Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received the vaccine, more commonly in males under 40 years of age than among females and older males. In most of these people, symptoms began within a few days following receipt of the second dose of the vaccine. The chance of having this occur is very low

Seek medical attention right away if you have any of the following symptoms after receiving the vaccine:

chest pain
shortness of breath
feelings of having a fast-beating, fluttering, or pounding heart
• Fainting can happen after getting injectable vaccines, including Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY® (COVID-19 Vaccine, mRNA). Sometimes people who faint can fall and hurt themselves. For this reason, your vaccination provider may ask you to sit or lie down for 15 minutes after receiving the vaccine

• Some people with weakened immune systems may have reduced immune responses to Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY® (COVID-19 Vaccine, mRNA)

• Additional side effects include injection site pain; tiredness; headache; muscle pain; chills; joint pain; fever; injection site swelling; injection site redness; nausea; feeling unwell; swollen lymph nodes (lymphadenopathy); decreased appetite; diarrhea; vomiting; arm pain; and fainting in association with injection of the vaccine

These may not be all the possible side effects of the vaccine. Call the vaccination provider or healthcare provider about bothersome side effects or side effects that do not go away.

• You should always ask your healthcare providers for medical advice about adverse events. Report vaccine side effects to the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) Vaccine Adverse Event Reporting System (VAERS). The VAERS toll-free number is 1?800?822?7967 or report online to www.vaers.hhs.gov/reportevent.html.
