More than 85,000 vaccines have been administered to individuals living in the seven ZIP codes in the Lake Houston area, according to the Texas Department of State Health Services.

As of March 22, ZIP code 77346 has the most vaccinated people, with 20,006. ZIP code 77345 has the highest percentage of vaccinated individuals as compared to its population, based on the population estimates for each ZIP code from the U.S. Census Bureau's American Community Survey.

None of the Lake Houston-area ZIP codes are close to achieving the 80% mark that health experts have said will provide herd immunity.

Harris County has vaccinated more than 1 million individuals, and Montgomery County has vaccinated just over 100,000, 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. Beginning March 29, vaccinations will be available to all Texan adults.
