About 11% of the overall population of the area—which amounts to nearly 680,400 people—has been fully vaccinated against the virus. Experts recommend about 80% of the population needs to be vaccinated for herd immunity to be achieved, and Cy-Fair could get closer to that number soon, as all Texans age 16 and older became eligible for the vaccine Monday, March 29.
As of March 28, ZIP code 77433 had the highest percentage of its population fully vaccinated, with 16%, based on 2019 population estimates from the U.S. Census Bureau's American Community Survey. Just south of there in ZIP code 77449, that percentage falls to 8.4%.
While about 75,000 Cy-Fair residents have been fully vaccinated, nearly 165,000 have received at least one dose of the vaccine. The Moderna and Pfizer vaccines require two doses to be administered three to six weeks apart. The newest vaccine, from Johnson & Johnson, requires just one dose, according to the Centers for Disease Control and Prevention.
In Harris County, 1.1 million individuals have been partially vaccinated and more than 567,000 have been fully vaccinated as of March 31, according to DSHS data. Find more county-level information about the vaccine here.
