National immunisation coverage has increased for the first time in five years, for almost all vaccinations. For children born in 2017, vaccination coverage against mumps, measles and rubella (MMR) increased by 0.7% to 93.6%.

The percentage of newborns participating in the immunisation programme targeting mumps, measles and rubella rose slightly over the past year.

Research by RIVM shows that the participants in the so-called tROM project, their supervisors and other people involved may have been exposed to chromium-6.
