Four COVID-19 vaccines, which include primary series and boosters, are recommended in the United States.
Vaccine recommendations are based on age, the vaccine first received, and time since last dose.
People who are moderately or severely immunocompromised have specific recommendations for COVID-19 vaccines, including boosters.
Side effects after a COVID-19 vaccine are common, however severe allergic reactions after getting a COVID-19 vaccine are rare.
After a recipient receives a COVID-19 vaccination dose they will be given a vaccination certificate (white card). The vaccination certificate will include information about the date(s) of COVID-19 vaccine administration, vaccine manufacturer, lot number, and clinic (vaccine administration site) name.
