Dutch study shows COVID vaccines 97% effective in preventing ICU admission

“Among the unvaccinated population, the incidence of COVID-19 hospitalizations and ICU admissions is high, which, combined with the size of this population, could lead to a significant strain on health care in the coming months. A further increase in vaccination coverage is key to reduce the burden on health care,” concluded the team.

A majority of hospitalizations were from unvaccinated patients. Results showed that the likelihood of being hospitalized is smaller among vaccinated patients compared to unvaccinated people.

When fully vaccinated, vaccine effectiveness against hospitalization was 94% when Alpha was the dominant variant. Meanwhile, vaccines were 95% effective when Delta was dominant.

Similar results were observed in the ICU as unvaccinated people made up a majority of ICU admissions. When fully vaccinated, vaccines were 93% effective in preventing ICU admissions during the Alpha period. For Delta, vaccines were 97% effective.
