The state already allows for medical- and religious-based exemptions.
Honestly, we need to talk more about this. That is the most important line in this whole article, IMO. Fundamentally, this bill would have just re-iterated the status quo. Parents already have the right to claim that vaccines violate their sincerely held religious beliefs, and boom, their kids walk into school unvaccinated.
The FL Speaker wants to be seen standing up for the health of children, but as long as religious exemptions stand, his "stand" is pure performance.
Because anyone can make up a new religion, or simply create a new sect within an existing religion like Christianity - there are already arguably thousands of Christians sects in the USA - several catholic churches (Roman, Eastern Orthodox, and splinters off of or within those that hold heterodox views), plus many Protestant denominations, and thousands of independent churches that may have a lot of overlap in their interpretations of the Bible, but are free to go their own way and start adding new interpretations or getting rid of old ones.
If you have religious exemptions to laws, you don't have laws.
