Thank you @margbrennan for the great #COVID19 discussion on @facethenation this morning. Our decision to expand the Phase 3 trial would allow us to further increase population diversity as well as generate even more safety and efficacy data.
Volunteers from all over the country have raised their hands to participate, and now we want to expand to ensure we include more vulnerable populations.
We chose to fund our program without accepting taxpayer money so we could liberate our scientists from bureaucracy and allow them to focus solely on the scientific challenges.
@pfizer has begun manufacturing, at risk, so that if our vaccine candidate demonstrates safety and efficacy, and the FDA approves it, we will be ready. The safety and well-being of vaccinated individuals is our top priority. #WeStandWithScience.

Excited to share that updated analysis from our Phase 3 study with BioNTech also showed that our COVID-19 vaccine was 100% effective in preventing #COVID19 cases in South Africa. 100%! pfizer.com/news/press-rel…
800 participants enrolled in South Africa with 0 cases of #COVID19 observed in the vaccinated group. Of the cases observed the majority were confirmed to be of the B.1.351 lineage, the prevalent strain in South Africa.
These data support previous results from immunogenicity studies demonstrating a robust neutralizing antibody response to the B.1.351 variant.
Very happy to say that we have more good news to share. The final efficacy analysis of @Pfizer's Phase 3 study showed that our #COVID19 vaccine candidate met all of the study's primary efficacy endpoints: pfizer.com/news/press-rel…
Most notably, the vaccine candidate was shown to be 95% effective in helping prevent #COVID19 beginning 28 days after the first dose.
We also announced that the safety database required by the @US_FDA for Emergency Use Authorization (EUA) has been achieved.
From the bottom of my heart, I want to thank our Upjohn colleagues for their contributions over the years and dedication in helping us achieve this milestone. They have made our company stronger and helped us deliver meaningful value to patients around the world.
I know our Upjohn colleagues will deliver the same value for @ViatrisInc, which will combine best-in-class manufacturing, science experience and proven commercial capabilities to bring quality medicines to patients.
