The preliminary data show a robust increase in neutralizing antibodies targeting the LP.8.1 sublineage of SARS-CoV-2 following vaccination. These clinical findings reinforce pre-clinical data that supported the recent U.S. Food and Drug Administration (FDA) approval of the LP.8.1-adapted COVID-19 vaccine, which demonstrated<b \/>improved immune responses against multiple circulating SARS-CoV-2 sublineages.<\/p>\n<p>\nA total of 100 participants were enrolled in the open-label Phase 3 trial cohort, 50 adults aged 65 and older and 50 adults aged 18-64<i \/>with at least one underlying risk condition for severe COVID-19. Prior to receiving the LP.8.1-adapted COVID-19 vaccine 2025-2026 Formula, all participants had received the KP.2-adapted COVID-19 vaccine at least six months prior to enrollment and had not received any other COVID-19 vaccine or had COVID-19 disease since the KP.2 vaccination through enrollment in the study. Data from evaluable participants showed that the LP.8.1-adapted COVID-19 vaccine elicited a robust immune response against the LP.8.1 sublineage. In both age groups, 14 days following vaccination, LP.8.1-neutralizing antibody titers exceeded pre-vaccination levels, on average, by at least 4-fold. The safety profile of the vaccine was consistent with previous studies, with no new safety concerns identified.<\/p>\n<p>\nThe favorable neutralizing antibody responses and consistent safety profile of the LP.8.1-adapted vaccine for individuals with higher risk and who had been previously exposed to SARS-CoV-2 provide early information for prescribers for this year\u2019s vaccination period. This study was conducted to provide additional information about immunological effects of the vaccine and is not intended to replace the post marketing commitments requested by the FDA.<\/p>\n<p>\nTo date, 5 billion doses have been distributed globally of the Pfizer-BioNTech COVID-19 vaccine, which continues to demonstrate a favorable safety and efficacy profile supported by extensive real-world evidence as well as by clinical, non-clinical, pharmacovigilance, and manufacturing data. COVID-19 vaccines by Pfizer and BioNTech are based on BioNTech\u2019s proprietary mRNA technology and were developed by both companies. BioNTech is the Marketing Authorization Holder for COMIRNATY<sup>\u00ae<\/sup> and its adapted vaccines in the United States, the European Union, the United Kingdom, and other countries, and the holder of emergency use authorizations or equivalents in other countries.<\/p>\n<p><b><span class=\"bwuline\">U.S. INDICATION AND IMPORTANT SAFETY INFORMATION<\/span><\/b><\/p>\n<p><b>INDICATION<\/b><\/p>\n<p>\nCOMIRNATY (COVID-19 VACCINE, mRNA) is a vaccine to protect against coronavirus disease 2019 (COVID-19).<\/p>\n<p>\nCOMIRNATY is for people who are:<\/p>\n<ul class=\"bwlistdisc\">\n<li>\n65 years of age and older, or<\/p>\n<\/li>\n<li>\n5 years through 64 years of age with at least one underlying condition that puts them at high risk for severe outcomes from COVID-19.<\/p>\n<\/li>\n<\/ul>\n<p><b>IMPORTANT SAFETY INFORMATION<\/b><\/p>\n<ul class=\"bwlistdisc\">\n<li>\nYou or your child should <b>NOT <\/b>get COMIRNATY<sup>\u00ae<\/sup> (COVID-19 Vaccine, mRNA) if you or your child had a severe allergic reaction after a previous dose of COMIRNATY or any Pfizer-BioNTech COVID-19 vaccine or to any ingredient in these vaccines<\/p>\n<\/li>\n<li>\nThere is a remote chance that COMIRNATY could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose.

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 preclinical and clinical data (including Phase 1\/2\/3 or Phase 4 data), including the data discussed in this release for BNT162b2, any monovalent or bivalent vaccine candidates or any other vaccine candidate in the BNT162 program in any of our studies in pediatrics, adolescents, or adults or real world evidence, including the possibility of unfavorable new preclinical, clinical or safety data and further analyses of existing preclinical, clinical or safety 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, in real world data studies or in larger, more diverse populations following commercialization; the ability of BNT162b2, any monovalent or bivalent vaccine candidates or any future vaccine to prevent COVID-19 caused by emerging virus variants; the risk that more widespread use of the vaccine will lead to new information about efficacy, safety, or other developments, including the risk of additional adverse reactions, some of which may be serious; the risk that preclinical and 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 and interpretations; whether regulatory authorities will be satisfied with the design of and results from these and any future preclinical and clinical studies; whether and when submissions to request emergency use or conditional marketing authorizations for BNT162b2 in additional populations, for a potential booster dose for BNT162b2, any monovalent or bivalent vaccine candidates or any potential future vaccines (including potential future annual boosters or re-vaccination), and\/or other biologics license and\/or emergency use authorization applications or amendments to any such applications may be filed in particular jurisdictions for BNT162b2, any monovalent or bivalent vaccine candidates or any other potential vaccines that may arise from the BNT162 program, including a potential variant-based, higher dose, or bivalent vaccine, and if obtained, whether or when such emergency use authorizations or licenses will expire or terminate; whether and when any applications that may be pending or filed for BNT162b2 (including any requested amendments to emergency use or conditional marketing authorizations), any monovalent or bivalent vaccine candidates (including the submissions to regulatory authorities for the COVID-19 vaccine tailored to the KP.2 sublineage of the SARS-CoV-2 Omicron JN.1 lineage), or other vaccines that may result from the BNT162 program may be approved by particular regulatory authorities, which will depend on myriad factors, including making a determination as to whether the vaccine\u2019s benefits outweigh its known risks and determination of the vaccine\u2019s efficacy and, if approved, whether it will be commercially successful; decisions by regulatory authorities impacting labeling or marketing, 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, clinical trial sites or third-party suppliers; risks and uncertainties related to changes to vaccine or other healthcare policy in the U.S.;

potential third-party royalties or other claims related to our COVID-19 vaccine; the risk that other companies may produce superior or competitive products; risks related to the availability of raw materials to manufacture or test a vaccine; challenges related to our vaccine\u2019s formulation, dosing schedule and attendant storage, distribution and administration requirements, including risks related to storage and handling after delivery by Pfizer; the risk that we may not be able to successfully develop other vaccine formulations, booster doses or potential future annual boosters or re-vaccinations or new variant-based vaccines or combination vaccines; the risk that we may not be able to maintain or scale up manufacturing capacity on a timely basis or maintain access to logistics or supply channels commensurate with global demand for our vaccine, which would negatively impact our ability to supply the estimated numbers of doses of our vaccine within the projected time periods as previously indicated;
