More than half of all Texas seniors have received at least one dose of the COVID-19 vaccine, and 30 percent of those are fully vaccinated. The number of COVID-19 positive patients in Texas hospitals has fallen by two-thirds from its peak in mid-January. There are about five million Texans between the ages of 50 and 64. Now they are eligible, with more than 1 million of them already vaccinated, according to the DSHS report.
