• Initial agreement provides up to 40 million doses to COVAX in 2021
• First deliveries are expected to take place in Q1 2021 subject to the execution of supply agreements under the COVAX Facility structure
• For the COVAX Advanced Market Commitment 92 countries, Pfizer and BioNTech will provide the vaccine to COVAX at a not-for-profit price.

Pfizer and BioNTech SE today announced an advance purchase agreement with COVAX for up to 40 million doses of the Pfizer-BioNTech COVID-19 Vaccine. The doses will be delivered throughout 2021. COVAX is a global initiative coordinated by the Global Alliance for Vaccines and Immunization (GAVI), the Coalition for Epidemic Preparedness Innovations (CEPI) and the World Health Organization (WHO), to ensure equitable access to COVID-19 vaccines for all countries, regardless of income levels. COVAX includes an Advanced Market Commitment (AMC) financial mechanism that aims to ensure that 92 low- and lower-middle-income countries will be able to secure access to COVID-19 vaccines at the same time as higher-income countries. The first doses are expected to be delivered in the first quarter of 2021, subject to the negotiation and execution of supply agreements under the COVAX Facility structure. For the COVAX Advanced Market Commitment 92 countries, Pfizer and BioNTech will provide the vaccine to COVAX at a not-for-profit price. "At Pfizer, we believe that every person deserves to be seen, heard and cared for. That's why from the very beginning of our vaccine development program, Pfizer and BioNTech have been firmly committed to working toward equitable and affordable access of COVID-19 vaccines for people around the world," said Pfizer Chairman & CEO Albert Bourla. "We share the mission of COVAX and are proud to work together so that developing countries have the same access as the rest of the world, which will bring us another step closer to ending this global pandemic and proving that Science Will Win for everyone, everywhere." ?SARS-CoV-2 does not differentiate between borders ? a global pandemic requires comprehensive solutions and worldwide collaboration. COVAX is a truly global initiative and we are happy to support by making BNT162b2 available in many low- and lower-middle-income countries to help protect vulnerable people worldwide,? said Ugur Sahin, M.D., CEO and Co-founder of BioNTech. ?The urgent and equitable roll-out of vaccines is not just a moral imperative, it is also a strategic and economic imperative,? said Dr. Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization. "This agreement with Pfizer and BioNTech will enable COVAX to save lives, stabilize health systems and drive the global economic recovery.? ?Today marks another milestone for COVAX: in addition to securing access to doses, we are now expecting the first deliveries of life-saving COVID-19 vaccines in Q1. This is not just significant for COVAX, it is a major step forward for equitable access to vaccines, and an essential part of the global effort to beat this pandemic. We will only be safe anywhere if we are safe everywhere,? said Dr Seth Berkley, CEO of Gavi, the Vaccine Alliance, which leads COVAX procurement and delivery. As part of a broader strategy to support developing countries beyond the agreement with COVAX, Pfizer and BioNTech are committed to partnering with other global health stakeholders to provide expertise and resources that can strengthen healthcare systems where greater support may be needed to deploy COVID-19 vaccines. This includes analyzing supply chains and piloting novel approaches in low-income countries to address transportation and storage challenges. Pfizer and BioNTech are also committed to coordinating with international agencies to support supply and distribution in refugee and other vulnerable populations. Financial terms of the agreement were not disclosed. The Pfizer-BioNTech COVID-19 Vaccine has not been approved or licensed by the U.S. Food and Drug Administration (FDA), but has been authorized for emergency use by FDA under an Emergency Use Authorization (EUA) to prevent Coronavirus Disease 2019 (COVID-19) for use in individuals 16 years of age and older.

Pfizer assumes no obligation to update forward-looking statements contained in this release as the result of new information or future events or developments. This release contains forward-looking information about Pfizer?s efforts to combat COVID-19, the collaboration between BioNTech and Pfizer to develop a potential COVID-19 vaccine, the BNT162 mRNA vaccine program, an agreement with Singapore to supply BNT162 and other potential agreements, and modRNA candidate BNT162b2 (including qualitative assessments of available data, potential benefits, expectations for clinical trials, anticipated timing of regulatory submissions, regulatory approvals or authorizations, and anticipated manufacturing, distribution and supply), involving substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Risks and uncertainties include, among other things, the uncertainties inherent in research and development, including the ability to meet anticipated clinical endpoints, commencement and/or completion dates for clinical trials, regulatory submission dates, regulatory approval dates and/or launch dates, as well as risks associated with clinical data (including the Phase 3 data), including the possibility of unfavorable new preclinical or clinical trial data and further analyses of existing preclinical or clinical trial data; the ability to produce comparable clinical or other results, including the rate of vaccine effectiveness and safety and tolerability profile observed to date, in additional analyses of the Phase 3 trial and additional studies or in larger, more diverse populations upon commercialization; the risk that clinical trial data are subject to differing interpretations and assessments, including during the peer review/publication process, in the scientific community generally, and by regulatory authorities; whether and when additional data from the BNT162 mRNA vaccine program will be published in scientific journal publications and, if so, when and with what modifications; whether regulatory authorities will be satisfied with the design of and results from these and any future preclinical and clinical studies; whether and when any biologics license and/or emergency use authorization applications may be filed in Singapore and any particular jurisdictions for BNT162b2 or any other potential vaccine candidates; whether and when any applications that may be pending or filed for BNT162b2 may be approved by particular regulatory authorities in Singapore, which will depend on myriad factors, including making a determination as to whether the vaccine candidate?s benefits outweigh its known risks and determination of the vaccine candidate?s efficacy and, if approved, whether it will be commercially successful; decisions by regulatory authorities impacting labeling, manufacturing processes, safety and/or other matters that could affect the availability or commercial potential of a vaccine, including development of products or therapies by other companies; disruptions in the relationships between us and our collaboration partners or third-party suppliers; risks related to the availability of raw materials to manufacture a vaccine; challenges related to our vaccine candidate?s ultra-low temperature formulation and attendant storage, distribution and administration requirements, including risks related to handling after delivery by Pfizer; the risk that we may not be able to successfully develop non-frozen formulations; the risk that we may not be able to create or scale up manufacturing capacity on a timely basis or have access to logistics or supply channels commensurate with global demand for any potential approved vaccine, which would negatively impact our ability to supply the estimated numbers of doses of our vaccine candidate within the projected time periods indicated; whether and when additional supply agreements will be reached; uncertainties regarding the ability to obtain recommendations from vaccine technical committees and other public health authorities and uncertainties regarding the commercial impact of any such recommendations; uncertainties regarding the impact of COVID-19 on Pfizer?s business, operations and financial results; and competitive developments.
