Data and Statistics

County Vaccination Coverage

The County of San Diego Health and Human Services Agency's Immunization Program conducts periodic Random Digit Dialing (RDD) telephone surveys. Interviewers make phone calls to randomly selected phone numbers to assess immunization coverage rates for San Diego County residents.

Surveys provide valuable data to determine what proportions of infants, children, adults and seniors living in San Diego County are fully immunized. The information collected helps us plan programs to do a better job of protecting all San Diegans from vaccine preventable diseases.

We measure our progress against the immunization component of the Healthy People objectives set by the federal Department of Health and Human Services. The objectives are science-based, 10-year national objectives for improving the health of all Americans. It is important to note that these goals are reviewed regularly and changed to reflect the latest immunization recommendations.

Vaccine Coverage Statistics: A Work in Progress

At the time of the last local survey (2016-2017) we found that we had met the 2020 goal of 80% of San Diego preschool children getting the following vaccines: four doses of DTaP (diphtheria, tetanus, and pertussis), three doses of polio, one dose of MMR (mumps, measles, and rubella), three doses of hepatitis B, three doses of Hib (Haemophilus influenzae B), one dose of varicella (chickenpox) and 4 doses of pneumococcal pneumonia (PCV). The graph below shows the trend of immunization coverage nationally and in California as well as San Diego County from 2009-2017. (click on image below to enlarge)

As noted earlier, the Healthy People goals are adjusted as immunization recommendations change, based on the latest science available. The 2020 goal added 4 doses of the PCV vaccine to the coverage measurements. This vaccine, which protects against certain types of pneumococcal disease is recommended for children at 2, 4, 6, and 12-15 months of age.

The County of San Diego Health and Human Services Agency’s Immunization Program continues to work with its community partners, both organizations and individuals, to improve immunization rates in the County. Staff and partners are always looking for new and innovative ways to increase the effectiveness of immunization promotion and education efforts. Those efforts never cease; every year there is always a new population of babies who need immunizations to protect them from serious, vaccine-preventable diseases. 

The coverage rates for each vaccine were analyzed separately. The vaccine coverage rates in the latest survey were compared to a baseline measurement to determine what progress has been made over the years. Many vaccine coverage rates exceeded the baseline measurement, including those for Hepatitis B vaccine, Varicella vaccine, and Hepatitis A vaccine. (click on image below to enlarge)

Below is a graph with coverage rates for adolescents. The coverage rates for each vaccine were analyzed separately. Similarly to the preceding graph, the vaccine coverage rates in the latest survey were compared to previous measurements to determine what progress has been made over the years. In all cases, there were substantial increases in coverage. (click on image below to enlarge)

Below is a graph with coverage rates for adults. The coverage rates for each vaccine were analyzed separately. As in the preceding graphs, the vaccine coverage rates in the latest survey were compared to previous measurements to determine what progress has been made over the years. In each of the vaccines measured, except the Pneumococcal vaccine among adults 18-64 yrs with high risk conditions, the coverage rates increased from previous years.(click on image below to enlarge)

The final graph contains coverage rates for the flu vaccine in various age groups. And, similarly to the preceding graphs, the vaccine coverage rates in the latest survey were compared to previous measurements to determine what progress has been made over the years. Most age groups showed increases in coverage over previous years, but all, except for the 65 years and older group, are still below the Healthy People 2020 goal. (click on image below to enlarge)

Telephone immunization survey phone calls will be taking place through October 30, 2022.
