Texas has largely left the vaccine rollout process in the hands of local providers like Tarrytown Pharmacy, one of more than 1,000 providers approved to vaccinate Texans.

Seemingly overnight, many Texas hospitals, health centers and pharmacies’ phone lines were clogged. Across the state, the vaccine providers quickly realized “first come, first served” was not working.
