Telephone Immunization Survey

The County of San Diego Health and Human Services Agency's Immunization Unit conducts periodic telephone surveys. Surveyors make phone calls to randomly selected phone numbers during weekdays, weekday evenings and on Saturdays.

This survey provides valuable data to determine what percentage of infants, children, adults, seniors, and health care workers living in San Diego County are fully immunized. The information collected helps Public Health do a better job of protecting all San Diego County residents from vaccine preventable diseases.
