Fair Park reopened on Wednesday after Dallas County received 15,000 new doses of the Moderna vaccine for those who need their second shot. But, with so many needing their second dose at once, it led to people waiting hours.
Last week's freeze delayed 20,000 people from getting their booster and this week the county is focused on completing the the series.
Wednesday was supposed to be for those who missed their second dose before Feb. 16 and Thursday for those due before Feb. 17.
Dallas County Judge Clay Jenkins encouraged people to come later or on Thursday to avoid the long lines.

The county said there is a shuttle system at the DART Fair Park Station, located at 3710 Parry Ave., for those who don't have transportation. But, on Wednesday, people parked their cars and walked to the shuttle.
Some say the total process took two hours on the bus as opposed to the four for those who waited in line.
As the day went on, the line did thin out and Jenkins tweeted about the progress.
The Federal Emergency Management Agency (FEMA) also launched its new program at Fair Park targeting those in under-served areas.
About 200 military personnel could be seen at the end of the drive-thru line helping with shots.
