Introduced by state Senator Richard Pan, a Democrat from Sacramento, "The Keep Schools Open and Safe Act" would not only prohibit families from claiming a personal belief exemption concerning California's COVID-19 student vaccine requirement, but it would also add these vaccines to the state's list of required inoculations for those attending K-12 schools. Only in the case of a rare medical exemption, could a student opt out of getting the vaccine...

But some on the other side of the political aisle don't see the measure as anything but negative.

"Now it is clear. The government doesn't want your family to have a choice. Government is in control. Either get vaccinated or get kicked out of school," tweeted California Assemblyman James Gallagher Monday. "I am absolutely going to oppose removing COVID vaccine exemptions for school children. This is wrong and an unconscionable overreach into the family over a virus that poses very minimal threat to young children."
