Polio vaccines are safe now, but in the early days they were ineffective and dangerous. It took about 20 years for a safe, reliable vaccine to be developed.

All of my kids and their friends had the polio vaccine in the 60s……no problems at alll.

I don’t know why you refer to it as formerly dangerous….good lord.
