It's like trusting oil companies to help humanity when everyone well knows they lobby the government to get their way to access more oil in foreign lands, even if it means to engage in warfare.
My issue with putting trust behind the studies saying vaccinations are perfectly fine is that corporations once again are known to fund mislead research to protect their interests. Forgive me to use cannabis as an example, but it's broad enough to show how much effort they put into making false claims that it's extremely unhealthy to both physical and mental health. Today the research has done a 180 because the government is slowly but surely easing up on the research which was once heavily restricted.
