Texas governor says state is 'very close' to herd immunity. The data tells a different story. Reis Thebault, The Washington Post April 12, 2021 FacebookTwitterEmail Texas Gov. Greg AbbottRicardo Brazziell /TNS Texas Gov. Greg Abbott said "simple math" is behind the recent decline of coronavirus cases in his state: Take the number of people who have been vaccinated and combine it with the number who have been infected. The result, he said, is something "very close" to herd immunity - the point at which enough of the population is immune that the virus can no longer easily spread. "We remain very vigilant and guarded and proactive in our response, but there is simple math behind the reason why we continue to have success," Abbott, a Republican, said on "Fox News Sunday." The equation "means, very simply, it's a whole lot more difficult for covid-19 to be spreading to other people in the state of Texas."
