Methodist Hospital received more than 5,000 doses, which is part of their 13,650 allotment.
When the vaccines arrive, they go into freezers with a temperature of -80 degrees Celcius. That's about -112 degrees Fahrenheit, which is colder than the surface of Mars.
The doses are stored in the freezer room until they're ready to thaw for the shots.
Officials have only five minutes to move the vials into a freezer to make sure they stay cold enough to be effective. The stakes are high with the vaccine as it's all about timing.
"We've got to have a thawing time of 30 minutes. If we thaw it out, it lasts us up to six hours. So we've got six hours of administration time," explained Binita Patel with Memorial Hermann Pharmacy Services.
