According to GECKO, one reason that contributes to the rapid spread of omicron is the significantly higher proportion of asymptomatic infected people compared to omicron (15 percent) and beta/delta (2.6 percent). For older groups of people (65+) there is now also evidence that implies that the booster vaccination is similarly effective in this age group as in the general population (risk reduction for severe courses by 94 percent). There are significant differences in hospitalization rates between unvaccinated and vaccinated subjects, with the risk of hospitalization for Omicron in subjects with booster shots being reduced by 81 percent compared to unvaccinated/<28 days since first vaccination. A risk reduction was also observed after two vaccinations, writes the commission in its current report.
“Vaccinations only provide limited protection against infection with omicron, but protect very well against a serious illness,” emphasize the experts. In the future, vaccination will focus on reducing the burden of disease. This means that administering the third vaccination as quickly as possible is of central importance.
