My thoughts...
1. Even pre-COVID, there have been people who were anti-vaxxers. They homeschooled their their children since they were not vaccinated against rubella, polio, smallpox, measles, etc.
2. I find it interesting that some people will question the contents of the COVID vaccines, but have never questioned the ingredients of the other vaccines, nor the contents of a frankfurter or oreo cookie.
3. In 2019, we stood on lines for hours for a Popeye's chicken sandwich, never stopping to think about what is in it that made it so addictive.
