Pfizer is one of various vaccine manufacturers participating in Operation Warp Speed as a supplier of a potential COVID-19 vaccine," Castillo said in an email. "While Pfizer did reach an advanced purchase agreement with the U.S. government, the company did not accept (Biomedical Advanced Research and Development Authority) funding for the research and development process. All the investment for R&D was made by Pfizer at risk. Dr. Jansen was emphasizing that last point.
CEPI estimates that developing up to three vaccines in the next 12–18 months will require an investment of at least 2 دولار أمريكي billion. This estimate includes Phase 1 clinical trials of eight vaccine candidates, progression of up to six candidates through Phase 2 and 3 trials, completion of regulatory and quality requirements for at least three vaccines, and enhancing global manufacturing capacity for three vaccines.

It is vital that we evaluate as many vaccines as possible as we cannot predict how many will turn out to be viable. To increase the chances of success (given the high level of attrition during vaccine development), we must test all candidate vaccines until they fail. [The] WHO is working to ensure that all of them have the chance of being tested at the initial stage of development. The results for the efficacy of each vaccine are expected within three to six months and this evidence, combined with data on safety, will inform decisions about whether it can be used on a wider scale.
