I am only partly "anti-vaxxer" as you say - I hope you use a better term in your paper though. If not, you will look biased.
What I look at is a combination of things.
First, does the particular vaccine sometimes do harm to the recipient? How often? How well has its safety or lack of safety been proven? It cannot be denied that this sometimes happens.
Second, how effective is it, and for how long? How well is this proven?
Third - and this is a deal-breaker for me - does it contain "diploid cells"? These cells are, in fact, human cells grown from an unborn child that was aborted for this purpose. Keep in mind that there are obviously various avenues for research on vaccines - Why did they focus in on this particular way of doing it?
So you see, I judge each vaccine on a case-by-case basis.
