Metro Health and the San Antonio Zoo are teaming up to provide vaccinations, with an added incentive. Anybody who gets a shot will receive a free ticket to the zoo's "Dino Land and Dragon Forest" experience. Dragon Forest is a wooded kingdom populated with 15 dragons. The attraction also includes food, drinks, and live entertainment. Metro Health will offer the Pfizer vaccine at a mobile clinic. First doses are today through Thursday, and second doses are August 9th to the 12th, from 11 a.m. to 6 p.m.
