Covid-19 Vaccine Efficacy Estimates
Researchers can measure how effective a vaccine is at preventing disease by following vaccinated and unvaccinated individuals in clinical trials or observational studies. By comparing the incidence of infections in vaccinated and unvaccinated groups, researchers can estimate what’s known as vaccine efficacy. This term describes the reduction of disease in a vaccinated group of people compared to an unvaccinated group, if all other conditions remain the same. A large reduction of disease in a vaccinated group, when compared to an unvaccinated group, equates to a highly effective vaccine.
