COVID-19 Hospitalization Risk by Vaccine Status
Remaining up to date on vaccination reduces the risk of hospitalization due to COVID-19. Older adults who are not up to date on vaccination are at especially high risk for hospitalization.
Up to date on vaccination includes people who have received their recommended COVID-19 booster doses, people who have completed a primary vaccine series recently – in the last five months for mRNA vaccines (Pfizer or Moderna), or the last two months for the Johnson & Johnson vaccine, and people 50 or older who received their first booster dose in the last four months.
Not up to date on vaccination includes people who have not completed a primary vaccine series, people who completed the mRNA vaccine series more than five months ago or the Johnson & Johnson vaccine more than two months ago and have not received a booster, and people 50 or older who had their first booster more than 4 months ago and have not had a second booster.
The risk of hospitalization is defined as the number of people hospitalized per 100,000 people of each vaccination status.
