I’m British but have lived in France since my youngest was 5 months old. Both my children had to have a full programme of vaccinations (I think it’s 11 in total) before starting nursery / school. I’m surprised to find out that there aren’t any mandatory vaccinations for children going into a group setting here in the UK and wondered how that would go down if it was required? Especially now that there seen to be rising numbers of children are not being vaccinated against serious illnesses such as measles.
