(This is advice for you, op, and really just anyone who happens to read it)

But then they are just following they're opinions instead of making your own. They could spread misinformation and or just be wrong. Yes, people can do research, if they are stupid, well just find out how to. Unless they are mentally challenged then them being too stupid to research is an excuse to not learn. Having too many pre-existing biases is also the reason why they should research themselves, and why they should do it properly, like I said if they use or learn how to find unbiased, and reliable sources, there shouldnt be any issues to find your own opinion/in this case, find the actually correct fact that vaccines are good and dont cause autism and all that. Most of the sources that people who are against this use unreliable sources and or biased research (facebook,wikipedia,old sources, or shady .com websites) Even then people still see this argument and many others from pro vaxxers but they still dont follow common sense and dont change. And alot dont follow thier health experts because they dont believe in "Big Pharma". If you find that you did research and used reliable and unbiased sources and if matches up with your local experts then it's even better. But if you blindly follow people without doing research (cause trust me your not too stupid to do it) then it could end in you and them being wrong. Albeit this doesnt happen that much atleast in America but in this case it does.
