Vaccinations are now the victims of their own success.
Due the growth of the number of unvaccinated children over the past few years in Europe, the herd immunity – whereby chains of infection are more able to be disrupted when large numbers of a population are immune to a disease – of the general population has been lost. As a result, those too young to be vaccinated are at significantly greater risk of being infected.
If you don’t vaccinate you’re risking the health of your kids and that of all the kids around you. The more people that fail to vaccinate, the greater this risk becomes.
