In the period from 27 June 2023 to 18 September 2023, the risk of hospital admission due to COVID-19 for people aged 60 years and older who received a repeat vaccination against COVID-19 in the 2022 autumn round was still lower than for people over 60 who had previously received at least one COVID-19 vaccination, but had not received a repeat vaccination in the 2022 autumn round. The relative risk difference (RRD) for hospital admission was -21% (95% CI: -34;-5). This RRD is significantly lower than shortly after the 2022 autumn round.
People who do not have the same vaccination status may also have differences in vulnerability (underlying health conditions), the number of previous infections, and the number of vaccinations they received before the autumn round. For that reason, a comparison between people with a different vaccination status cannot be exclusively used to indicate vaccine effectiveness for the 2022 autumn round.
This is the last update reporting on COVID-19 hospital admissions in relation to the 2022 autumn round of vaccinations. The next update will report on the 2023 autumn round. The update will be posted once sufficient data is available on COVID-19 hospital admissions after the start of the 2023 autumn round.
2 October 2023 will mark the start of the 2023 autumn round for everyone who has a higher risk of serious illness or death due to COVID-19. Care workers who have direct patient and/or client contact and pregnant women can also get the COVID-19 vaccination.
