Your contribution helped drive these insights
35,278 people contributed information about their experience with COVID infections and vaccinations and this is what we learned
- All 3 vaccines (Pfizer, Moderna, and J&J) were highly effective for preventing COVID infection (95% reduction), and those of you who did get infected had much milder symptoms including protection from breakthrough infections.
- There were very few severe side effects and many of you reacted more to the second dose than the first dose of two-dose vaccines.
- Fewer side effects were reported by people who had a seasonal flu vaccine before their COVID vaccine.
