The department said the staff administered 5,451 doses of the vaccine as of 6 p.m. on Saturday, and there was a glitch in the system that caused it to overbook appointments.

We're unable to accommodate the volume of people in line. Our staff is taking names of people in line who have appointments to re-schedule for a future date. #hounews pic.twitter.com/z2pasRuDaV
As of 6 p.m., we administered 5,451 doses.— Houston Health Dept (@HoustonHealth) January 17, 2021
We will look into what caused us to go over our scheduled appointments today and ensure it's corrected.
We apologize for the inconvenience as we all work together to end this pandemic. #hounews @houmayor @HoustonTX @HoustonOEM https://t.co/wL7IrCYtqF
Several people left without getting vaccinated before the overbooking announcement was made because the line outside Minute Maid Park wrapped around half of the building.
"It seems like it's very unorganized," said Elizabeth Patterson, who was one of the people to leave the long line after waiting for hours. "What's the point of making an appointment if you're going to stand here for three to four hours to get in and then you might not even get it?"
Moayyad Razzok and his wife, Shatha, said they received the first dose of the Moderna vaccine at the clinic on Saturday. They waited for hours and said it was cold but applauded the department's process.

"I don't think there's enough nurses," Moayyad said. "It was good, you know, we can get the vaccine, at least, here in Houston. There's people around the world right now that don't have the chance to get it."
At a press conference Saturday afternoon, Stephen Williams, Director of the Houston Health Department, said earlier this week Mayor Sylvester Turner pushed to get out as many vaccines out this weekend, and the department agreed to administer 5,000 doses.
"Although I said, 'Mayor if we give out 5,000 (doses), that means we're not going to have enough for the next week,'" Williams said. "But, he insisted that we get out as much as we could."

Williams went on to say he was proud of the staff, volunteers and partners that helped put their operation together to administer the doses on Saturday.
ABC13 put in an inquiry with the Mayor's office and the city's health department regarding the alleged 'glitch' in the system. This was the response from a spokesperson with the Houston Health Department:
"Our vaccine supply info is on our website. We scheduled approx 5k appointments today but went over.
On January 14, the health department received an additional 8,200 doses of vaccine, bringing its total to 30,350.
As of January 15, the department administered a total of 21,025 doses at locations including Minute Maid Park, Bayou City Event Center, its Northside, La Nueva Casa de Amigos, Sharpstown and Sunnyside health centers, the JW Peavy Senior Center, and its Acres Homes, Hiram Clarke and Magnolia multi-service centers.
Approximately 5,000 people are scheduled to for vaccination at the health department's Minute Maid Park mega site on January 16.
The department also transferred a total of 1,900 doses to other providers."
Turner said on Twitter that the city of Houston vaccinated 6,122 people, and the health department tried to accommodate everyone who showed up. There were still many who had to be rescheduled or turned away.
Today at Minutemaid the City of Houston vaccinated 6122. The Health Department tried to accommodate everyone who showed up and there were still many who had to be rescheduled or turned away. I want to thank the employees, Astros, HFD, HPD, and Rodeo volunteers. st— Sylvester Turner (@SylvesterTurner) January 17, 2021
He also said earlier on Saturday that the demand for the vaccine was greater than the current supply.

"Even if every one of you had every online system working perfectly," Turner said. "Every call in (to the) system was working perfectly. You are still going to have most people not able to get the vaccine because the supply is not available. You heard that Dr. Williams say that up to this point, the city of Houston has received a little more than 30,000 doses. Now put that in context. There are 2.3 million people in the city of Houston. There are another 4 million people in the county. These doses are made available for not just people in the city of Houston, but people in the county and people in the surrounding region. There is not enough supply for the demand, when everybody is wanting the vaccine right now. That's not system failure."
