About Personal Belief Exemptions
At the start of the school year, kindergarteners must have been adequately vaccinated for polio, diphtheria, tetanus, whooping cough, measles, mumps, rubella, hepatitis B and chicken pox (or have had chicken pox). Under some circumstances, a child may start kindergarten if he or she is not fully vaccinated and does not have a personal belief exemption or permanent medical exemption, but these children are considered "conditional entrants," and the school must follow up, according to the California Department of Public Health.

It's easy for parents in California to get a personal belief exemption for their child. They need only sign a statement provided on their school’s immunization form. Some other states make it tougher, requiring parents to write a letter explaining their decision. Ironically, it's easier to opt out of school vaccinations in California than to provide documentation of a child's vaccination history. A very small fraction of children cannot receive immunizations for medical reasons and receive a "permanent medical exemption."
