"Vaccines have never been proven safe and effective in a Court of Law"

It is not, and never has been, the duty of a court of law to determine if a vaccine is either "safe" or "effective'.

Instead we have a separate legal entity that determines both the safety and efficacy of all medicine, and that separate legal entity *HAS* determined that vaccines are both safe and effective.

If this ever came up in court (and it probably has) it would be a dead-simple case to simply open up the file and confirm that YES, the vaccines are both safe and effective.
