If you don't have a lot of experience in the field thinking you can do better original research or synthesis than the experts is probably not reasonable.

You don't need to hold that belief to think that the experts are wrong. The expert might be wrong because they are willing to downplay the risks associated with vaccination because they think the benefit from higher vaccination rates outweigh the cost.

There also a huge commercial interest in the experts supporting vaccination.

Experts can be wrong and it's often useful to read papers yourself.

In my experience, if there is a field where there is a big consensus opinion among "experts", and a small group of wacko's on the internet contesting the "expert's" finding with their own citations to the scientific literature, if I've investigated and read what the science says, the wacko's have turned out right every time.

The problem with your quick way of investigating is its based on the utterly fallacious theory that annointed "experts" know what they are talking about. In general, they are just spouting crowd think.

“Science is the belief in the ignorance of experts.” ― Richard P. Feynman

'A foolish faith in authority is the worst enemy of truth.' --Albert Einstein

"To return to the faculty of observation possessed by crowds, our conclusion is that their collective observations are as erroneous as possible, and that most often they merely represent the illusion of an individual who, by a process of contagion, has suggestioned his fellows... "The events with regard to which there exists the most doubt are certainly those which have been observed by the greatest number of persons. To say that a fact has been simultaneously verified by thousands of witnesses is to say, as a rule, that the real fact is very different from the accepted account of it." --Gustav Le Bon, The Crowd, 1895.

"Vaccination is a barbarous practice and one of the most fatal of all the delusions current in our time. Conscientious objectors to vaccination should stand alone, if need be, against the whole world, in defense of their conviction.” ― Mahatma Gandhi
