Gov. Greg Abbott of Texas may have been overly optimistic on Sunday when he said on Fox News that his state could be “very close” to herd immunity — the point where so much of the population is immune to Covid-19, either from being vaccinated or previously infected, that the virus can no longer spread.
“When you look at the senior population, for example, more than 70 percent of our seniors have received a vaccine shot, more than 50 percent of those who are 50 to 65 have received a vaccine shot,” Mr. Abbott, a Republican, told Chris Wallace. Mr. Wallace had asked why statewide infection, hospitalization and death rates were more under control than in other states, in spite of Texas reopening many activities and eliminating mask mandates.
The governor added, “I don’t know what herd immunity is, but when you add that to the people who have immunity, it looks like it could be very close to herd immunity.”
Michael Osterholm, an epidemiologist and director of the University of Minnesota’s Center for Infectious Disease Research and Policy, said, “There is no way on God’s green earth that Texas is anywhere even close to herd immunity.”
