How many people need to get a COVID- 19 vaccine for herd immunity? Herd immunity means that enough people in a community are protected from getting a disease because they’ve already had the disease or they’ve been vaccinated. Herd immunity makes it hard for the disease to spread from person to person, and it even protects those who cannot be vaccinated, like newborns. While experts don’t yet know what percentage of people would need to get vaccinated to achieve herd immunity, vaccination is a safer way to build protection than getting sick with COVID-19.Have a question about COVID-19 vaccines?
