How many people need to get a #COVID19 vaccine for population immunity? When enough people in a community are protected from getting a disease – because they’ve already had the disease or they’ve been vaccinated – that makes it harder for the disease to spread from person to person. This is known as population immunity, 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 population immunity, vaccination is a safer way to build protection than getting sick with COVID-19.
