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.
