My neighbours son had encephalitis during a bout of mumps he was vaccinated and both his parents are doctors.
He was ill for a very long time and never fully recovered. Very sad and just goes to show that being vaccinated isnt a 100% guarantee.
That's so sad.
Yes, there are failures in vaccines and that is another reason why we need to keep the 'herd immunity' as near to 100% as possible. Some kids can't have it and for some it doesn't work, so the less chance there is of those coming in to contact with the diseases the better.
I think I will agree to disagree with you
