In spring/summer 2023, the virus will likely circulate less. The current virus variants also cause rather mild illness.

In principle, it is also not currently recommended for people at especially high risk to receive a COVID-19 vaccination.

Other vaccinations with inactivated vaccines can also be administered before, at the same time as or after a COVID-19 vaccination. Vaccine We advise you to get vaccinated with a bivalent (i.e. variant-adapted) mRNA vaccine, or with the protein-based Novavax vaccine. Which vaccine(s) you have previously received is of no importance here. Please note: If you are pregnant or breastfeeding, or if you have a severely weakened immune system, you should get yourself vaccinated with an mRNA vaccine.
