I will work on my PhD project at RIVM. The project is about the chronobiological optimisation of vaccinations. So I’m interested in finding out at what time of the day vaccines should be administered to offer the best protection against pathogens, like the influenza virus and SARS-CoV-2. Specifically, the objective is to determine the effect of vaccination timing on the immunological response and to assess the resulting change in the burden of the disease.
