Immunization Information

All Central Valley students must be up-to-date on childhood immunizations, in accordance with Washington State requirements. School nurses routinely review student records to ensure immunizations are up-to-date.

There have been a few changes in the immunization requirements in the past few years.
Varicella / Chicken Pox
All students in grades K-12 are required to have had two Varicella (chicken pox) vaccines, have Health Care Provider (HCP) documentation of disease, or show immunity through serological testing in order to attend school.
This vaccine protects against tetanus, diphtheria, and pertussis. In the past, no one over the age of 7 could receive a vaccination against pertussis (whooping cough). It has been found that immunity against pertussis can wane by adolescence. The 2012 pertussis epidemic in the state of Washington has shown that this has greatly increased the incidence of the disease that can be deadly to infants. The Tdap vaccine is recommended for all children aged 11 and older. This vaccine should replace one tetanus-diphtheria (Td) booster. All students attending our middle schools and high schools will need to show proof of vaccination.
Meningococcal & HPV
There are two vaccinations that are optional for adolescents to receive. One is the Meningococcal vaccine that will prevent certain types of meningitis. This is an important vaccine for all students who will be living in shared living situations such as dormitories or military barracks. The other vaccination to consider is the HPV (human papilloma virus) vaccine, which has been shown to prevent pre-cancerous lesions of the cervix.
