California lawmakers are advancing tougher rules for vaccinations despite hearing hours of testimony from hundreds of opponents. The Senate Health Committee voted 6-2 in favor of the bill despite more than three hours of often emotional pleas from parents and sometimes children who say the measure would interfere with parental rights. Supporters of SB276 say unvaccinated students are helping to spread measles outbreaks in California and elsewhere. Just a few years ago, SLO County experienced a measles outbreak. The last case of measles was reported in May 2018.
