Booster vaccinations reduced the risk of dying from COVID-19 in 2022. The risk of death from other causes was also lower for people who had a booster jab than for people without a booster jab. These findings are from research by RIVM.

Young people aged 12–25 feel that the COVID-19 pandemic made them miss out on a key stage of their lives. They have indicated that important milestones, such as graduation ceremonies or the start of student life, passed them by. This is evident from the latest quarterly study conducted by the Network for Health Research in Disasters.

A new RIVM study has shown that the COVID-19 pandemic intensified existing socio-economic differences. People on lower incomes visited test lanes less often during the pandemic, but were admitted to hospital and intensive care with COVID-19 more often.

An international audit committee of scientific experts, commissioned by the RIVM Scientific Advisory Board, reviewed the institute’s COVID-19 data analytics and modelling work. These models and data formed a scientific basis for recommendations by the Outbreak Management Team (OMT) and others on COVID-19 control measures in the Netherlands. 

RIVM has published the code for model projections of COVID-19 hospital and ICU admissions. The code has been shared as part of a manuscript about the model.

After a SARS-CoV-2 infection involving Omicron, 1 in 10 people still have symptoms three months later. This is almost 2 times lower than after an infection involving the Delta variant. This is evident from new results of the LongCOVID study at RIVM. There is variation in the frequency of specific post-COVID symptoms after an infection with the Omicron or Delta variant.

The consequences of infections involving the coronavirus SARS-CoV-2 are decreasing. This is because nearly everyone in the Netherlands has built up immunity to COVID-19 as a result of vaccination and/or previous infection, and because the current Omicron variants are less likely to cause serious illness.
