Efforts by Republicans in Wisconsin also have shown some real momentum. State Senate Health Committee Chairman Patrick Testin (R) held a hearing this month that included Senate Bill 336. The bill would, among other things, prohibit schools and universities from excluding students because of their vaccination status. And, again, it’s not just about coronavirus vaccines.

Experts aren’t sure quite what that would mean, practically speaking, given that the legislation wouldn’t repeal state laws requiring students to get vaccines like those for polio and measles, mumps and rubella (MMR). As the Milwaukee Journal Sentinel reported, “School districts would then be responsible for enforcing the state’s vaccine requirements for students while being banned from denying admission or participation to students because of what vaccinations they have received.”

The author of the bill, state Sen. André Jacque (R), said it would not conflict with state law because parents can apply for waivers from such vaccine requirements. The question would seem to be: What happens if and when waivers are not granted and the students remain unvaccinated.
