Assessing vaccination coverage as part of a comprehensive intervention has been demonstrated to result in increased coverage rates. The National Immunization Survey provides coverage estimates at the national level and selected urban areas. However, it is important for other localities to understand vaccination coverage in their areas. The San Diego Immunization Branch conducts the San Diego Immunization Survey (SDIS) to gather vaccination coverage information in San Diego County. This article describes the methodology and results of the SDIS.


The SDIS is a two-phase immunization survey. The first phase is a random-digit-dialing survey in which vaccination information is obtained by phone. The second phase involves the verification of this information and/or obtaining vaccination information via the registry or the child's provider(s).


In 2005, the sample size included 839 respondents. From 1995 to 2005, coverage for the following individual vaccines increased: diphtheria and tetanus toxoids, and acellular pertussis (92.0% to 96.5% for > or = 3 doses, and 75.0% to 89.0% for > or = 4 doses), polio (83.0% to 94.7%), measles-mumps-rubella (85.0% to 95.8%), Haemophilus influenzae type b (87.0% to 93.2%), and hepatitis B (67.0% to 93.6%).


The results of the SDIS demonstrate that San Diego County has exceeded the Healthy People 2010 goal to reach at least 80% coverage for the series of universally recommended vaccinations.
