Antibodies to SARS-CoV-2, the virus that causes COVID-19, can be detected in the blood of people who have recovered from COVID-19 or people who have been vaccinated against COVID-19. Getting a vaccine is safer than getting COVID-19, and vaccination against COVID-19 is recommended for everyone ages 5 years and older.
Rates of COVID-19 hospitalizations remain high in children between the ages of 5 through 11 years. While COVID-19 is usually milder in children compared with adults, it can make children very sick. CDC recommends everyone ages 5 years and older get a COVID-19 vaccine to help protect against COVID-19.
