Pfizer and BioNTech Receive Positive CHMP Opinion for LP.8.1-Adapted COVID-19 Vaccine in the European Union

Data indicate that the LP.8.1-adapted COVID-19 vaccine confers improved immune response against currently dominant and emerging sublineages – including the XFG and NB.1.8.1 variants1 – compared to 2024-2025 COVID-19 vaccine formulationsUpon authorization by the European Commission (EC), the LP.8.1-adapted COVID-19 vaccine will be available for individuals 6 months of age and olderTo date, over a billion adults and children around the world have received the Pfizer-BioNTech COVID-19 vaccine, which continues to demonstrate a favorable safety and efficacy profile supported by extensive real-world evidence, clinical, non-clinical, pharmacovigilance and manufacturing dataDoses will be ready to ship to applicable EU member states immediately upon authorization by the European Commission NEW YORK and MAINZ, GERMANY, July 25, 2025 — Pfizer Inc. (NYSE: PFE, “Pfizer”) and BioNTech SE (Nasdaq: BNTX, “BioNTech”) announced today that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) has recommended marketing authorization for the companies’ LP.8.1-adapted monovalent COVID-19 vaccine (COMIRNATY® LP.8.1) for active immunization to prevent COVID-19 caused by SARS-CoV-2 in individuals 6 months of age and older. The adaptation is based on the recommendation from the EMA’s Emergency Task Force (ETF) to update COVID-19 vaccines to target the LP.8.1 variant for the 2025-2026 season. The ETF stated that “targeting LP.8.1 will help maintain the effectiveness of the vaccines as SARS-CoV-2 continues to evolve.”2 The CHMP’s recommendation will be reviewed by the European Commission (EC), which is expected to make its final decision soon. Pfizer and BioNTech have already initiated manufacturing of the LP.8.1-adapted monovalent COVID-19 vaccine at risk to ensure supply readiness ahead of the upcoming fall and winter season when the demand for COVID-19 vaccination is expected to increase. The updated vaccine will be available to ship to applicable EU member states immediately following the EC decision. The CHMP’s recommendation is based on the cumulative body of evidence previously submitted by Pfizer and BioNTech that includes clinical, non-clinical, and real-world data supporting the safety and efficacy of Pfizer and BioNTech COVID-19 vaccines. This application included non-clinical and manufacturing data showing that the LP.8.1-adapted monovalent COVID-19 vaccine generates overall improved immune responses against multiple circulating SARS-CoV-2 lineages, including XFG, NB.1.8.1, LF.7, and other currently circulating contemporary sublineages, compared to the companies’ JN.1 and KP.2-adapted monovalent COVID-19 vaccines.1 The companies have also submitted data for the updated COVID-19 vaccine to regulatory authorities around the world. The companies are continuing to monitor the evolving epidemiology of COVID-19 in preparation to meet global public health needs. The COVID-19 vaccines by Pfizer and BioNTech are based on BioNTech’s proprietary mRNA technology and were developed by both companies. BioNTech is the Marketing Authorization Holder for COMIRNATY® 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 the United States (jointly with Pfizer) and other countries. AUTHORIZED USE IN THE EU:COMIRNATY® ▼ has been granted standard marketing authorization (MA) by the European Commission to prevent coronavirus disease 2019 (COVID-19) in people from the age of 6 months. The vaccine is administered as a single dose in people 5 years of age and older, and as a three-dose series, in infants and children from 6 months to 4 years who have not completed a primary vaccination course and who have not had COVID-19 before, with the first two doses given three weeks apart, followed by a third dose given at least 8 weeks after the second dose. Adults and adolescents from the age of 12 are given 30 micrograms per dose; children aged 5 to 11 years are given 10 micrograms per dose; infants and children aged 6 months to 4 years are given 3 micrograms per dose. Additional doses may be administered to individuals aged 5 years and older who are severely immunocompromised in accordance with national recommendations. The European Medicines Agency’s (EMA’s) Committee for Medicinal Products for Human Use (CHMP) has completed its rigorous evaluation of COMIRNATY, concluding by consensus that sufficiently robust data on the quality, safety and efficacy of the vaccine are available. In addition, COMIRNATY has also been granted standard MA for three adapted vaccines: COMIRNATY Omicron XBB.1.5, which contains mRNA encoding for the spike protein of the Omicron XBB.1.5 subvariant of SARS-CoV-2, COMIRNATY JN.1, which contains mRNA encoding for the spike protein of the Omicron JN.1 subvariant of SARS-CoV-2 and COMIRNATY KP.2, which contains mRNA encoding for the spike protein of the Omicron KP.2 subvariant of SARS-CoV-2. COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 may be administered as a single dose regardless of prior vaccination status in people aged 5 years and older. Children from 6 months to 4 years of age may have one or three doses depending on whether they have completed a primary vaccination course or have had COVID-19. There should be an interval of at least 3 months between administration of COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 or COMIRNATY KP.2 and the last prior dose of a COVID-19 vaccine. IMPORTANT SAFETY INFORMATION Events of anaphylaxis have been reported. Appropriate medical treatment and supervision should always be readily available in case of an anaphylactic reaction following the administration of the vaccine.There is an increased, but very rare risk (<1/10,000 cases) of myocarditis and pericarditis following vaccination with COMIRNATY. These conditions can develop within just a few days after vaccination and have primarily occurred within 14 days. They have been observed more often after the second vaccination, and more often in younger males. Available data indicate that most cases recover. Some cases required intensive care support and fatal cases have been observed.Anxiety-related reactions, including vasovagal reactions (syncope), hyperventilation or stress‐related reactions (e.g. dizziness, palpitations, increases in heart rate, alterations in blood pressure, paresthesia, hypoesthesia and sweating) may occur in association with the vaccination process itself. Stress-related reactions are temporary and resolve on their own. Individuals should be advised to bring symptoms to the attention of the vaccination provider for evaluation. It is important that precautions are in place to avoid injury from fainting.Vaccination should be postponed in individuals suffering from acute severe febrile illness or acute infection. The presence of a minor infection and/or low-grade fever should not delay vaccination.As with other intramuscular injections, the vaccine should be given with caution in individuals receiving anticoagulant therapy or those with thrombocytopenia or any coagulation disorder (such as hemophilia) because bleeding or bruising may occur following an intramuscular administration in these individuals.Safety and immunogenicity of the vaccine have been assessed in immunocompromised individuals, including those receiving immunosuppressant therapy. The efficacy of COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 may be lower in immunosuppressed individuals.As with any vaccine, vaccination with COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 may not protect all vaccine recipients. Individuals may not be fully protected until 7 days after their vaccination.Adverse reactions observed during clinical studies and identified after post authorization experience are listed below according to the following frequency categories: Very common (≥ 1/10), Common (≥ 1/100 to < 1/10), Uncommon (≥ 1/1,000 to < 1/100), Rare (≥ 1/10,000 to < 1/1,000), Very rare (< 1/10,000), Not known (cannot be estimated from the available data). Very common side effects: Headache, diarrhea, arthralgia, myalgia, injection site pain, fatigue, chills, pyrexia, injection site swelling.Common side effects: lymphadenopathy, injection site redness, nausea, vomiting.Uncommon side effects: Hypersensitivity reactions (e.g. rash, pruritus, urticaria, angioedema), decreased appetite, insomnia, dizziness and lethargy, hyperhidrosis and night sweats, pain in extremity, asthenia, malaise, injection site pruritus.Rare side effects: acute peripheral facial paralysis.Very rare side effects: myocarditis, pericarditis.Not known incidence: anaphylaxis, paresthesia and hypoesthesia, erythema multiforme, heavy menstrual bleeding, extensive swelling of vaccinated limbs, facial swelling. No data are available yet regarding the use of COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1, and COMIRNATY KP.2 during pregnancy. However, there are limited clinical study data (approximately 300 pregnancy outcomes) from the use of COMIRNATY in pregnant participants. A large amount of observational data from pregnant women vaccinated with the initially approved COMIRNATY vaccine during the second and third trimester have not shown an increase in adverse pregnancy outcomes. While data on pregnancy outcomes following vaccination during the first trimester are presently limited, no increased risk for miscarriage has been seen. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryo/fetal development, parturition or post-natal development. Based on data available with other vaccine variants, COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 can be used during pregnancy.No data are available yet regarding the use of COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 during breast-feeding. Observational data from women who were breast-feeding after vaccination with the initially approved COMIRNATY vaccine have not shown a risk for adverse effects in breast-fed newborns/infants. COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 can be used during breast-feeding.Animal studies with COMIRNATY do not indicate direct or indirect harmful effects with respect to reproductive toxicity.Comirnaty Omicron XBB.1.5, Comirnaty JN.1 and Comirnaty KP.2 (30 micrograms/dose dispersion for injection) may be administered concomitantly with seasonal influenza vaccine.In adults 18 years of age and older, Comirnaty Omicron XBB.1.5, Comirnaty JN.1 and Comirnaty KP.2 may be administered concomitantly with a pneumococcal conjugated vaccine (PCV). an unadjuvanted recombinant protein respiratory syncytial virus (RSV) vaccine. In individuals 65 years of age and older, Comirnaty Omicron XBB.1.5, Comirnaty JN.1 and Comirnaty KP.2 may be administered concomitantly with an unadjuvanted recombinant protein RSV vaccine and a high dose influenza vaccine.The most frequent adverse reactions in infants 6 to 23 months of age that received any primary course dose included irritability (> 60%), drowsiness (> 40%), decreased appetite (> 30%), tenderness at the injection site (> 20%), injection site redness and fever (> 10%).The most frequent adverse reactions in children 2 to 4 years of age that received any primary course dose included pain at injection site and fatigue (> 40%), injection site redness and fever (> 10%).The overall safety profile of COMIRNATY in participants 5 to 11 years of age was similar to that seen in participants 16 years of age and older. The most frequent adverse reactions in children 5 to 11 years of age that received 2 doses were injection site pain (> 80%), fatigue (> 50%), headache (> 30%), injection site redness and swelling (≥ 20%), myalgia, chills, and diarrhea (> 10%).The overall safety profile for the booster dose was similar to that seen after the primary course. The most frequent adverse reactions in children 5 to 11 years of age were injection site pain (> 60%), fatigue (> 30%), headache (> 20%), myalgia, chills, injection site redness and swelling (> 10%).The overall safety profile of COMIRNATY in adolescents 12 to 15 years of age was similar to that seen in participants 16 years of age and older. The most frequent adverse reactions in adolescents 12 to 15 years of age that received 2 doses were injection site pain (> 90%), fatigue and headache (> 70%), myalgia and chills (> 40%), arthralgia and pyrexia (> 20%).The most frequent adverse reactions in participants 16 years of age and older that received 2 doses were injection site pain (> 80%), fatigue (> 60%), headache (> 50%), myalgia (> 40%), chills (> 30%), arthralgia (> 20%), pyrexia and injection site swelling (> 10%) and were usually mild or moderate in intensity and resolved within a few days after vaccination. A slightly lower frequency of reactogenicity events was associated with greater age.The safety profile for the booster dose was similar to that seen after 2 doses. The most frequent adverse reactions in participants 18 to 55 years of age were injection site pain (> 80%), fatigue (> 60%), headache (> 40%), myalgia (> 30%), chills and arthralgia (> 20%).The safety profile for the COMIRNATY Original/Omicron BA.4-5 booster (fourth dose) was similar to that seen after 3 doses. The most frequent adverse reaction in participants 6 to 23 months of age was irritability (> 30%), decreased appetite (> 20%), drowsiness, tenderness at the injection site and fever (> 10%). The most frequent adverse reactions in participants 2 to 4 years of age were injection site pain (> 30%) and fatigue (> 20%). The most frequent adverse reactions in participants 5 to 11 years of age were injection site pain (> 60%), fatigue (> 40%), headache (> 20%), and muscle pain (> 10%). The most frequent adverse reactions in participants 12 years of age and older were injection site pain (> 60%), fatigue (> 50%), headache (> 40%), muscle pain (> 20%), chills (> 10%), and joint pain (> 10%).The safety of COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 is inferred from safety data of the prior COMIRNATY vaccines.The duration of protection afforded by the vaccine is unknown as it is still being determined by ongoing clinical trials. As with any vaccine, vaccination with COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 may not protect all vaccine recipients.For complete information on the safety of COMIRNATY Omicron XBB.1.5, COMIRNATY JN.1 and COMIRNATY KP.2 always make reference to the approved Summary of Product Characteristics and Package Leaflet available in all the languages of the European Union on the EMA website.
