How effective is the COVID-19 vaccine?

There are multiple COVID vaccines at various stages of the development, approval and distribution process. The clinical trials for the Pfizer vaccine showed a 95% efficacy rate and 94% with the Moderna vaccine in preventing symptomatic COVID. That means the rate of catching COVID in vaccinated participants was only 5-6% of the rate seen in those who received placebo. There is still a small chance of infection post-vaccination. Masks and social distancing will be with us for some time to come. As with other vaccines, the more people who get immunized, the greater the community-wide protection against the disease.
