Vaccinate your child, because it protects more than just them.

Advice please...
I have just become aware that there is unvaccinated children in my mums group.
He is fully vaccinated for his age - 14 months.
He is the oldest in the group and the youngest is 12.5 months
I'm just wondering what risks there are for him even though he is vaccinated and also any new borns that join the group (at least one mum is pregnant again so far)

I have a vague memory of a add on TV that showed a baby struggling because they had whooping cough. Does anyone else remember or am I making it up? Anyway maybe some advertisements showing what happens if your child does contract a vaccine preventable disease would help pull some people of this false sense of security!!! This false sense of security comes from herd immunity. It's funny that vaccinations and the subsequent herd immunity is central to why some people aren't vaccinating - take them and plonk them in pre-vaccination times and they would be lining up for the injecting that could prevent another child from dying!
