Annual Virginia Immunization Survey


Purpose of Survey

The Virginia Department of Health conducts a retrospective survey annually of children in daycare facilities, Head Start programs, kindergartens and 6th grades to measure compliance with school required vaccinations.  Immunization histories from enrollees are collected by VDH and analyzed to assess their age-appropriate immunization status at specific ages.  Then data from the individual sites are combined into the respective category so statewide immunization rates can be calculated for each facility category.

Methods of Survey

All students enrolled in Virginia public and private day care centers, Head Start programs, kindergartens and six grades are candidates for assessment.  Using a statistical technique known as probability proportional to size, approximately 13,000 children from 600 sites are selected and examined for immunizations and their dates of administration.  Using the CoCASA assessment software, immunization rates for vaccine series completion at 24 months of age and as of the 1st day of school for both kindergartens and 6th grades are determined.  All data are handled confidentially.  Virginia allows only medical and religious exemptions.
