A recent study examines how the vaccines produced by Moderna and Pfizer might protect against COVID-19. RWE (real world evidence) shows that these vaccines are broadly effective—both in preventing infection and reducing incidence of serious disease. The Pfizer vaccine is 95% effective and the Moderna vaccine is 94.1% effective in preventing symptomatic COVID-19. The hospitalization rate among people who received either vaccine was reduced compared to unvaccinated people. The article is available on medRxiv as it undergoes peer review.
The authors note, “Building upon the previous randomized trials of these vaccines, this study demonstrates their real-world effectiveness in reducing the rates of SARS-CoV-2 infection and COVID-19 severity among individuals at the highest risk for infection.” Read more here.
