[National Immunisation Programme: is vaccinating less an option?].

Many people are no longer familiar with the diseases that are part of the Dutch National Immunisation Programme (NIP). The protection given by the NIP has ensured that these diseases, most of them serious, have largely disappeared. The NIP has developed gradually, but in retrospect it was in 1957 that what we now know as the NIP started. Over the years, the NIP has gradually expanded to include various vaccines such as live attenuated vaccines, conjugate vaccines and vaccines that offer protection against chronic viral infections. Currently, the NIP offers protection against twelve different diseases. Occasionally the Netherlands still sees minor outbreaks of those diseases included in the NIP programme, generally among non-vaccinated people. It is important that the NIP is retained; stopping vaccination always leads to the return of the disease. The question is: can good protection be maintained with fewer injections? This subject is on the agenda of the Health Council Of The Netherlands for discussion in 2022.
