The state reported Tuesday that 163,700 Texans had been vaccinated with at least one dose of the vaccine. About 1.2 million doses have been allocated to providers across the state through the first three weeks since their arrival, according to the Department of State Health Services.

“A significant portion of vaccines distributed across Texas might be sitting on hospital shelves as opposed to being given to vulnerable Texans,” Gov. Greg Abbott said in a tweet Tuesday evening.

That tweet came after health officials asked providers that received doses of the COVID-19 vaccine to “immediately vaccinate” all eligible Texans, including people 65 and older and those who are at least 16 with a qualifying medical condition. That renewed push echoed a statement Dr. John Hellerstedt, commissioner of the Texas DSHS, sent to providers last week directing them to “administer their entire allotment with all deliberate speed.”
