You have to factor three things against each other to decide how worth it a vaccine is to take. 1 is how deadly the disease is. 2 is how harmful the vaccine is. 3 is how well the vaccine works to stop the disease. You need to have a pretty good idea on all three things to make a logical decision and every vaccine for every disease will have different numbers.
This is not only true, but applicable to any medical decision that you make - vaccine, medication, surgery, etc. The reality is that any healthcare decision a patient makes has a "benefit versus risk" component. That includes the decision to do nothing at all.
It's a conversation that I literally have at least 20 times a week.
In terms of research, like anything else, it requires a critical eye. It really doesn't matter if big pharma, organizations with an agenda, politicians, etc., fund or support a research project. IF the methodology, accrual, analysis, etc., is done correctly, the information is valid. The same can be said of a truism, regardless of the messenger. Just because you don't like or trust a person doesn't necessarily mean that everything they state is therefore false.
As for vaccines (and research in general), there is a distinction between the science and the way it is used and/or messaged. Calling out politicians, big pharma and lobbyists for manipulating scientific information for nefarious intentions absolutely is fair game but the science is science.
That said, I completely agree with you that the evidence that children and otherwise healthy people benefit from the vaccine is highly questionable, and that every vaccine should be judged by its own merits. Also, there is a "greater good" aspect to vaccinations. That's not necessarily a bad thing. I have many libertarian views, but some edicts make sense - I don't want to put my family in danger of small pox because a group of people are "anti-vaxxers," much like I don't want a billion people deciding to bankrupt the healthcare system by exercising their right to smoke three packs a day, live on Krispy Kreme donuts and drink a fifth of Wild Turkey every day. There has to be some degree of social responsibility.
The real question is, who decides what that level of responsibility entails?
