I greatly appreciate how vaccines help prevent disease, but like any medication, there can be adverse side effects depending on personal biology. Furthermore, they load up these vaccines with a lot of nasty chemicals.
If you look at how a lot of these vaccines trials are structured, they do a lot of sketchy things. Like instead of using saline as the placebo, they use the previously approved version of the vaccine, or inject all the chemicals, but just not the actual virus culture. That way negative side effects are even in both groups. Of course, it doesn't mean that vaccines are safe across the board.
