 The research and development of Pfizer COVID-19 vaccine, which was proven to be 90% effective against SARS-CoV-2 in November 2020, was funded by U.S. President Donald Trump’s Operation Warp Speed.

 Agreeing to a buy a vaccine once approved is not the same as funding its research and development.

 “Pfizer is proud to be one of various vaccine manufacturers participating in Operation Warp Speed as a supplier of a potential COVID-19 vaccine,” Sharon Castillo, a Pfizer spokesperson, told Snopes in an email. “While Pfizer did reach an advanced purchase agreement with the U.S. government, the company did not accept the Biomedical Advanced Research and Development Authority (BARDA) funding for the research and development process. All the investment for R&D and manufacturing has been made by Pfizer at risk.”
