Is vaccination really that important for newborns? My friend hasn't got it done on her son and he seems to be doing fine. But as a soon-to-be mum, I am confused. Could somebody please advise.

In my opinion. It’s better to have your newborn vaccinated to prevent from serious ilness. Your friend’s son seems to be ok right now but if he exposed to the virus that already mention in the comment before, it might have a serious effect compare to the already vaccinated one.
