NEW YORK and MAINZ, GERMANY, November 3, 2022 — Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced the advancement of an mRNA-based combination vaccine candidate for influenza and COVID-19 to a Phase 1 trial with the aim to address two severe respiratory diseases with one vaccine. The first participant has been dosed in a Phase 1 trial evaluating the safety, tolerability, and immunogenicity of a nucleoside-modified RNA (modRNA)-based combination vaccine approach.

The vaccine candidate combines Pfizer’s quadrivalent modRNA-based influenza vaccine candidate, qIRV (22/23), which is currently in Phase 3 clinical development, and Pfizer and BioNTech’s authorized Omicron-adapted bivalent COVID-19 BNT162b2 (Original/Omicron BA.4/BA.5) vaccine, each of which is based on BioNTech’s proprietary mRNA platform technology.

“The flexibility and manufacturing speed of the mRNA technology has demonstrated that it is well-suited for other respiratory diseases. Pfizer is deeply proud of our continued work to explore its potential to protect against influenza and COVID-19 in one combination vaccine, which we think could simplify immunization practices against these two respiratory pathogens, potentially leading to better vaccine uptake for both diseases,” said Annaliesa Anderson, Ph.D., Senior Vice President and Chief Scientific Officer, Vaccine Research and Development, Pfizer. “Even with existing seasonal influenza vaccines, the burden of this virus is severe across the world causing thousands of deaths and hospitalizations every year. This is an exciting step in our ongoing journey with BioNTech as we collectively look to transform the prevention of infectious diseases around the world.”

“By combining both indications in one vaccine approach, we aim to provide individuals with an efficient way to receive immunization against two severe respiratory diseases with evolving viruses that require vaccine adaptation,” said Prof. Ugur Sahin, M.D., CEO and Co-founder of BioNTech. “The data will also provide us with more insights on the potential of mRNA vaccines addressing more than one pathogen. This will help us to further develop our infectious disease pipeline to deliver on patient centric vaccination approaches.”

About the Phase 1 Study
The BioNTech-sponsored, randomized Phase 1 study is designed to evaluate the safety, immunogenicity, and optimal dose level of a combined vaccine candidate against COVID-19 and influenza and is being conducted in the United States, aiming to enroll 180 healthy volunteers 18 through 64 years of age. The follow-up period for each participant will be a total of six months.

The vaccine candidate is based on BioNTech’s proprietary mRNA platform technology and contains mRNA strands encoding the wild-type spike protein of SARS-CoV-2 and the spike protein of the Omicron BA.4/BA.5 subvariants as well as mRNA strands encoding the hemagglutinin of four different influenza strains, recommended for the Northern Hemisphere 2022/23 by the World Health Organization. Hemagglutinin is a surface protein of the influenza virus which plays a role in the initiation of infection. The influenza virus is subject to constant mutations to evade the host immune response, causing a seasonal variation in circulating strains.

The new development program builds on the companies’ success in developing the first approved and most widely used mRNA vaccine as of todayⁱ to help prevent COVID-19. The companies will share the development costs. This is the fourth collaboration between Pfizer and BioNTech in the infectious diseases field, following the influenza vaccine collaboration initiated in 2018, the COVID-19 vaccine collaboration initiated in 2020 and the shingles vaccine collaboration initiated in 2022.

About Respiratory Diseases
SARS-CoV-2 led to a global pandemic with more than 6.5 million deathsⁱⁱ and a severe socio-economic burden worldwideⁱⁱⁱ. While vaccinations can help address the disease, COVID-19 is expected to remain a circulating, severe respiratory disease, requiring adjustments of vaccines to variants of concern. This is reminiscent of influenza, another respiratory disease that requires repeated vaccinations due to its genomic instability resulting in modifications of the surface protein hemagglutinin. Influenza accounts for up to 12,000 to 52,000 deaths in the United States every year^iv and equally concerning numbers in the European Union^v. A combined vaccine approach, based on BioNTech’s proprietary mRNA platform technology, has the potential to alleviate the impact of both diseases while offering a combined administration which has the potential to simplify immunization practices for health care providers as well as individuals in need. Additionally, with the flexibility and versatility of mRNA technology, vaccine candidates can potentially be adjusted rapidly to virus variants and aim to offer a valuable solution in the race against virus mutations in both COVID-19 and influenza.
