i am catching myself at the thought that before the coming of vaccines i was sure i will wait a few years till we have solid results based on years of study, as has been the case with other vaccines. and yet seeing people vaccinated, it sounds like one may be an outsider if s/he doesn't follow the flow... so can we say science has moved on and we can rely on it? or should we remember that scientists are just human beings who can do mistakes too?
