As far as I'm concerned, no one is supposed to do anything. You do what you decide is best. Hunches and assumptions sound like a bad way to decide on such an important course of action. Instead, if I were you, I'd do a combination of research and choosing someone to listen to that you think is both trustworthy and has spent a long time learning about vaccines. Maybe someone who's got a PhD in molecular biology and has written extensively on the subject.

Do your own research, and trust that person to understand the things that would take too long for you to learn, then make your choice.

I would never let the government do my thinking for me, for free or for pay. They aren't good at it.
