Overview of vaccination events

Study on heterologous vaccination schedules

Until now, it has been common practice to administer the same COVID-19 vaccine in two doses (homologous vaccination schedules). Multiple studies on heterologous vaccination schedules are being conducted and more and more data on immunogenicity and reactogenicity is being published. A recent German study on a vaccine regimen involving initial AstraZeneca vaccination followed by an mRNA vaccination showed that the series induced strong humoral and cellular response was found with acceptable reactogenicity profile. A Health Council advisory report on COVID-19 vaccination involving heterologous vaccination schedules is expected soon.

Updated implementation guidelines for COVID-19 vaccination

The implementation guidelines for COVID-19 vaccination 2021 have been updated. The latest version of the implementation guidelines is always available online (in Dutch). Section 1.3 outlines all major changes compared to the previous version; more minor interim changes are listed under Version Management (at the end of the document).
