A phone line set up for members of the public to schedule vaccination appointments in Houston was temporarily overwhelmed Saturday after it was inundated with hundreds of thousands of calls.
Around 250,000 people called the Houston Health Department Covid-19 call center to make an appointment to receive the Moderna vaccine, according to Houston Mayor Sylvester Turner.
The high volume of calls led to technical issues forcing the health department to switch to an on-site appointment system. The call center has since re-opened, according to Turner.
"We are working efficiently to vaccinate eligible frontline employees and vulnerable Houstonians," said Turner in a press release.
"The virus has taken a toll, especially among the elderly and black and brown communities. The vaccine is our best shot to help prevent people from getting sick and potentially suffering severe consequences."
The State of Texas' distribution plan prioritizes people 65 and older and people 16 and older who have at least one chronic medical condition, putting them at increased risk.
