People from Ukraine residing outside of the country are advised to contact health authorities or visit a COVID-19 vaccination center in the host country to assess their COVID-19 vaccination status and receive any outstanding doses. They should start or continue receiving COVID-19 (and any other) vaccinations according to the national guidelines of the host country.

WHO recommends that eligible individuals who have received one documented COVID-19 vaccine dose should receive the second dose and a booster dose. Eligible individuals with two documented doses of COVID-19 vaccines should receive a booster dose. For best protection a person should receive all recommended doses, regardless of whether they have previously had COVID-19 disease.
