Close to 50% of Texans age 12 and older had received at least one dose of the COVID-19 vaccine as of May 17, according to the state’s dashboard. In El Paso County, more than 440,00 people had received an initial dose.

Here’s what to know about getting vaccinated in El Paso:

Who are providers vaccinating?

The Pfizer vaccine is approved for use in people age 12 and up, and the Moderna and Johnson & Johnson vaccines are available for those 18 and older.

The Pfizer and Moderna vaccines require two doses given between 21 to 28 days apart, while the Johnson & Johnson vaccine is a single dose.

Who is giving out COVID-19 vaccines?

The state sends doses to mass vaccination hubs as well as doctor’s offices, community health clinics and pharmacies. El Paso’s hubs are run by the University Medical Center of El Paso and the city of El Paso. You can find smaller vaccine providers here.

The federal government also sends doses directly to select CVS, Walgreens, Walmart and Sam’s Clubs stores, as well as to the El Paso Veterans Affairs Health Care System.
