KUT A vial of the COVID-19 vaccine Pfizer BioNTech provided to healthcare workers at Dell Medical School on Dec. 15. Local health officials hope the Food and Drug Administration's approval of the Pfizer vaccine for children between 12 and 15 will help boost herd immunity in the Austin area. While Austin Public Health isn't offering the Pfizer vaccine (at least for now), there are plenty of options for Austinites to get a first dose of that or other vaccines this weekend. Here's a rundown. UT Health The University of Texas at Austin is offering first doses of Pfizer's COVID vaccine to pre-registered patients or people without appointments. Walk-in spots are available at UT's Health Transformation Building from 9 a.m. to 11 a.m. and 1:30 p.m. to 3 p.m., Monday through Friday. You can also pre-register at UT Health's website.
