L’ALTOIANO – The vaccination campaign against diphtheria, tetanus, polio (DTP) and mumps, measles, rubella (MMR) for 9-year-olds is restarting. During this autumn campaign, GGD Groningen invites all children who will turn nine in the fourth quarter of this year and children who have not yet arrived in the spring. All children who qualify for DTP / MMR injections will receive a home invitation letter. The letter indicates where and when they can get the two hits.
