Anyone commenting here who is sure vaccines are fine, please read this, especially if you are considering vaccinating kids.

TL;DR virtually all vaccines are only tested for safety by comparison with other vaccines, which themselves may have adverse events, rather than against a placebo which does not.
This obscures any general side effects of vaccines.
The control vaccines themselves are either tested against other vaccines (hence the title), or date from a time before clinical trials.
And anyone who thinks pharma and the medical establishment can be trusted, please google opioid crisis, maddie de garay, vioxx for starters.
