Immunization Requirements

Learn more about the state mandated vaccinations

A new state law (SB 277) requires that all children are fully immunized before entering kindergarten and seventh grade.

image006.jpgThe goal from the new law is simple: Greatly reduce the risk of serious and life-threatening diseases of children – and throughout the community. Certainly, immunizations do not eliminate the chance of contracting one of these diseases – as we learned from the measles outbreak at Disneyland in 2014 and more recently at a local charters school – but it significantly reduces the risk.

Nevada County has among the lowest fully immunized rates for children entering kindergarten at 73%, compared to the much-higher statewide average of 90%. It’s critical that parents immunize their children in order to follow the law, which went into effect Jan. 1, 2016, and protect the health of their family and the community.

You can learn more about the current immunization issue and the health risks from a Nevada County presentation by Salina Zomat, Krystal Scott and Nicole Fink, RN final semester nursing students, California State University, Sacramento, April 2016. The students had on-site training in the spring of 2016 at Western Sierra.

We’ve also compiled some additional information about the new state law, including the immunizations required for children to enroll and attend school:


If a child has not been fully immunized they cannot attend any, nor be accepted for first time enrollment to any of the following, regardless of personal or religious beliefs…

  • Family Day Care
  • Nursery Care
  • Development Center
  • Public School
  • Private School
  • Charter School
  • Secondary School (Seventh Grade or higher)

There are a few persons who may be exempt…

  • Any student  with an affidavit on file that exempts them from immunization with their school or care center before January 1, 2016, stating beliefs opposed to immunization, are exempted, so that they may finish their current grade span. There are two spans: K-6 and 7-12 should it continue after July 1, 2016. However, they must comply with the immunization requirement to be enrolled for the next grade span. For example, if a student completed sixth grade and was entering seventh grade this fall.
  • Children exposed to a specified disease, with documented proof of status excluding them from a particular immunization, are exempt.
  • Children enrolled in an independent study program, with no classroom-based instruction, are exempt
  • Children with an IEP (individualized education program) may receive special education-related services, outside a classroom, while on home-study are exempt.


The complete list of required immunizations:

  1. Diphtheria
  2. Hepatitis B
  3. Haemophilus influenza type B
  4. Measles
  5. Mumps
  6. Pertussis (whooping cough)
  7. Poliomyelitis, commonly referred to as polio
  8. Rubella
  9. Tetanus
  10. Varicella, also known as chickenpox

What does this mean?

If you have a toddler, you can take them to daycare if they have completed their required immunizations, otherwise, the daycare center must deny their enrollment, even for a single day. 

It also means if your child is currently in sixth grade, and has an exemption on file with the school before January 1, 2016, they will be able to finish their current school year without the immunization, but will need all immunizations to attend seventh grade.
