Personally I have reasons for a few extra vaccinations and we had our son vaccinated but the .gov requiring it is just another threat. But all "refugees" should be vaccinated. Governor moonbeam's logic on anything is questionable. Jerry Brown signs bill requiring childhood vaccinations - SFGate .................. Gov. Jerry Brown signed controversial legislation Tuesday that will make California one of the strictest states in requiring children to be vaccinated before attending public and private schools or day care, beginning in January. Noting the “widespread interest and controversy” surrounding SB277, Brown said he signed the bill because “the science is clear that vaccines dramatically protect children against a number of infectious and dangerous diseases.” SB277 eliminates an exemption many parents have used to opt their children out of some of all of the 10 required school vaccines, based on personal or religious beliefs. The new law takes effect on Jan. 1. But even after that date, children enrolled in school or day care who are unvaccinated because of a personal belief exemption can continue to attend until their next scheduled vaccine check. Such checks occur in kindergarten, seventh grade or when students enter a new school.
