HOUSTON — About 60% of the COVID-19 vaccine doses that have spoiled since Texas’ vaccination program began in December were wasted in the past two weeks, according to an analysis of state data.

According to a Houston Chronicle analysis of the roughly 60,000 vaccine doses spoiled since December, about 36,000 were lost in the past two weeks, indicating plummeting demand for the vaccine in Texas.

The number of wasted doses through spoilage of the highly perishable vaccine was still a minute fraction of the state’s vaccine allotment. The state is currently administering an average of about 144,000 vaccinations daily. Even so, that was less than half of the 290,000-vaccination-a-day peak last month.

Just one in three Texans were fully vaccinated against COVID-19 as of Thursday, mostly with the two-dose Pfizer and Moderna vaccines, while 42% have received at least one dose.

More than 51,000 people have died of COVID-19 in Texas during the 15-month pandemic out of the more than 3.2 million positive test results reported to the U.S. Department of Health and Human Services.
