What We are Still Learning
We are still learning how well vaccines prevent you from spreading the virus that causes COVID-19 to others, even if you do not have symptoms. We’re also still learning how long COVID-19 vaccines protect people. We are still learning how many people have to be vaccinated against COVID-19 before most people can be considered protected (population immunity). We are still learning how effective the vaccines are against new variants of the virus that causes COVID-19.
