Coronavirus updates: US reports nearly 300,000 new cases in all-time high

340,000 people have been vaccinated to date in Texas, out of the state's received allotment of 786,000 vaccination doses, according to data from Texas Health and Human Services.

Houston Mayor Sylvester Turner also authorized the Houston Health Department to open the city's first free COVID-19 vaccination clinic on Jan. 2. The clinic will expand vaccine access to the general public at high risk of severe illness and death from coronavirus disease, according to a statement from Texas health officials.

Texas' health department received its first allotment of 3,000 doses of the Moderna vaccine and started administering it on December 28.

The Houston Health Department will announce additional free vaccination opportunities as supply increases.

Despite repeated warnings not to travel for the holidays from the Centers for Disease Control and Prevention, 14,388,562 people passed through Transportation Security Administration (TSA) checkpoints between Dec. 18 and Dec. 31.

Still, that number pales in comparison to previous years. In 2019, 33,242,050 people were screened by the TSA at U.S. checkpoints during the same period.

Three new cases of the new COVID-19 variant first identified in the U.K. were reported by health officials in San Diego Thursday, leading them to believe there's community-wide transmission of the new variant in the area.

The new variant, known as B. 1.1.7., has also been detected in Colorado and Florida, and is believed to be more transmissible than the old variant, but not thought to be more deadly.

"We believe that many more cases of the B. 1.1.7. strain will be confirmed in the coming days and weeks," Dr. Eric McDonald, medical director of epidemiology and immunizations services at the country health department, said in a statement.
