Pfizer and BioNTech’s vaccine is reportedly successful in preventing 90% of infections according to early data from a Phase 3 study.
However it’s … important to stress that the results are preliminary and a successful vaccine is not a given yet. Here are … things to understand:
- The vaccine requires two doses
- We don’t know of the vaccine works on severe COVID-19 cases or how long it will be effective.
- We don’t know if vaccinated people can still carry the disease.
- If approved, most people will be waiting a while to get the vaccine.
