2004 RANDOM DIGIT DIALING (RDD)
IMMUNIZATION SURVEY RESULTS

The County of San Diego Health and Human Services Agency's Immunization Program conducted its annual Random Digit Dialing (RDD) telephone survey from March through June of this year. More than 40 surveyors made phone calls to randomly selected phone numbers during weekday evenings and on Saturdays to assess immunization coverage rates for San Diego County residents.

This survey provides 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.

The following graphs display some selected results of the survey. For more information about the RDD Survey, please call the Immunization Branch at (619) 692-8661.

Different telephone and school surveys have shown that increasing percentages of San Diego County preschool children are getting vaccinated. We have almost reached the Healthy People 2000 goal of 90% getting four doses of DTaP (diphtheria, tetanus, and pertussis), three doses of polio, and one dose of MMR (mumps, measles, and rubella) vaccines.

Our telephone surveys found that we have met the Healthy People 2010 goal of 80% of San Diego County preschool children getting all the standard vaccines. These include: 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 influenza B), and one dose of varicella (chickenpox).

The percentage of San Diego County residents age 65 and over getting the flu and pneumococcal vaccines has been consistent each year. Our flu vaccine coverage is higher than most of the U.S. and California.

Our telephone survey found that about half of people aged 18 – 64 who have chronic health conditions got the flu vaccine in the past year. Fewer had ever received the pneumococcal pneumonia vaccine.
