Negative effects from the vaccines, if they do show up, will take a while to do so. And its a safe bet that if any do show up, they'll turn the mutating virus into a far bigger threat than it ever was in the first place.

Its also safe to say that in the event unforeseen problems do manifest themselves, the public wont be blaming the weak governments, and 'Experts' that promoted vaccine uptake, oh no, the blame will be pinned on those who took the time to do their own research, and held back.
