There may be other reasons I'm not aware of to turn it down but for the lady I met at baby and bumps group today to be turning it down for this reason seems foolish and selfish.
I've seen a small child with whooping cough abroad. Its very distressing and I'd do anything reasonable to protect children from it.
So AIBU to think that turning it down just because you don't like needles or injections is wrong? I'm so glad DS (18 weeks) has now had the full course of early vaccines which included whooping cough
