All five of the people in the Moderna trial who developed COVID-19 after receiving the vaccine were white. As a result,  the Moderna vaccine was 100% effective in Black, Latino and Asian Americans, as well as in people with mixed racial backgrounds. 

In its Phase 3 trial, the Pfizer vaccine was 100% effective for Black study participants and 94.5% effective for Latino participants, slightly below the 94.7% effectiveness for white subjects. In addition, it was 74.4% effective in Asian Americans, and 100% effective in Native Americans and Pacific Islanders.

The Moderna vaccine was 100% effective at preventing cases of severe COVID-19. 

The Pfizer vaccine was 66.4% effective at preventing cases of severe COVID-19. 

The most common side effects for both vaccines were fatigue, headache, muscle pain, chills and joint pain. However, these were reported more often in the Moderna trial than the Pfizer trial.
