I'm worried for humanity but what can we do. I find it impressive that they have found all of the research that points to the dangers of vaccines with their phds in Google fu, but after years of previous research seem to have found none that argue against their point. It's honestly more likely in their minds that there is a massive conspiracy with vaccines than the fact they might be wrong and vaccines are effective and safe.
Is there potential for a vaccine reaction to occur? Sure there is, but that's with anything. When you wear a seat belt there's potential for it to get jammed when you get into an accident and cause you greater harm than good, but odds are you'll still wear your seat belt since it has a higher likelihood of preventing some serious injury that could occur should an accident happen. But yeah, do your research, only listen to those you agree with and validate your point, and continue living in bliss.
