"We believe that by pairing Pfizer's development, regulatory and commercial capabilities with BioNTech's mRNA vaccine technology and expertise as one of the industry leaders, we are reinforcing our commitment to do everything we can to combat this escalating pandemic, as quickly as possible."

"This is a global pandemic, which requires a global effort. In joining forces with our partner Pfizer, we believe we can accelerate our effort to bring a COVID-19 vaccine to people around the world who need it," said Ugur Sahin, Co-Founder and CEO of BioNTech.

The companies expect to utilize multiple research and development sites from both companies, including in the United States and Germany, to house the activities identified by the collaboration agreement.

The companies will begin collaborating immediately. They will finalize details of the agreement regarding financial terms, and all activities related to development, manufacturing and potential commercialization over the next few weeks.
