More than 113,000 vaccines have been administered to individuals living in the nine Spring-Klein-area ZIP codes, according to the Texas Department of State Health Services.

As of March 22, ZIP code 77379 has the most vaccinated people, with 29,355. However, ZIP code 77069 has the highest percentage of vaccinated individuals compared to its population, based on the population estimates for each ZIP code from the U.S. Census Bureau's American Community Survey.

Two of the Spring-Klein ZIP codes are close to halfway to the 80% mark that health experts have said will provide herd immunity.

Harris County has vaccinated more than 1 million individuals, according to the DSHS.

Groups eligible for the vaccine include the Phase 1A group—health care workers, first responders and residents of long-term care facilities; the Phase 1B group—people age 16 and older with a health condition that increases risk of COVID-19; the Phase 1C group—people ages 50-64; and education and child care workers. On March 29, vaccinations will become available to all Texan adults.
