In the past 8 weeks (18 October to 12 December 2022), the incidence of hospital admission was highest in the group of unvaccinated people over 80. The incidence of ICU admission was highest among people aged 70-79 years who had received the basic series of COVID-19 vaccinations, or were only partially vaccinated. The incidence of hospital and ICU admission in this period was lowest among people who had received a repeat vaccination in the autumn round. 

Differentiated by smaller age groups, RRD for hospital admission was -47% for people aged 40-59 years, -64% for people aged 60-79 years, and -59% for people over 80. There were too few admissions among people under 40 to estimate the RRD for the younger age groups.

People who do not have the same vaccination status may also have differences in vulnerability (underlying health conditions) or the number of SARS-CoV-2 infections they have had. Therefore, a comparison of hospital and ICU admission rates between people with different vaccination statuses cannot be exclusively used to indicate vaccine effectiveness.  

Everyone who has been invited to get a COVID-19 vaccination in the basic series, but has not yet done so, can still be vaccinated. In addition, since 19 September 2022, it is possible to get a repeat vaccination against COVID-19. This repeat vaccination in the autumn round is available to everyone aged 12 years and older who has at least completed the basic series of COVID-19 vaccinations. The vaccination is available from 3 months after the most recent COVID-19 vaccination or SARS-CoV-2 infection. The first invitations were sent to older people and people in medical risk groups, due to their higher risk of severe illness. Care workers who have contact with patients will also be invited. Since 26 October 2022, everyone aged 12 and older can get the repeat vaccination in the autumn round.
