Across the country, millions of people eagerly await their COVID-19 vaccinations. But many of them are encountering a big roadblock on the path toward eradicating the pandemic: scheduling their shots.

To overcome that hurdle, some organizations have turned to technology. San Antonio-based grocery chain H-E-B, for instance, will let customers schedule COVID-19 vaccinations through a web-based scheduler. As with H-E-B's app, many vaccination-scheduling tools are just now becoming available.

Houston's MD Anderson Cancer Center is one huge step ahead of the vaccination curve, though. Back in September, the hospital — part of the massive Texas Medical Center complex — started planning how it would roll out vaccinations for its more than 21,000-member workforce. As part of that planning, MD Anderson developed an in-house app enabling its employees to schedule their own vaccination appointments.

"We have an incredible team of informatics developers who worked in conjunction with our human resource and employee health leaders to design an app that's accessible on your phone or from any computer," says Dr. Welela Tereffe, chief medical executive at MD Anderson. "The app feeds you information about what appointments are available and then floats an appointment reminder to your calendar as well as sending you text reminders."

Beginning December 15, MD Anderson employees received the hospital's initial round of shots. They were the first employees who used the app to schedule appointments at workplace vaccination clinics. As of January 5, more than 8,700 hospital employees had been vaccinated with the first dose of either the Pfizer vaccine or Moderna vaccine. The immunizations are not mandatory. In all, 10,700 doses of COVID-19 vaccine have been shipped to MD Anderson since December 14, and every one of them is already spoken for.

Yolan Campbell, associate vice president of HR operations at MD Anderson, says the vaccination scheduling app built on knowledge the hospital's team had accumulated throughout 2020 in producing apps for COVID-19 tests and other pandemic-related purposes.

Tereffe notes that COVID-19 vaccination scheduling has "caused a lot of stress" for health care providers. MD Anderson hoped to avoid that stress by incorporating the app into its vaccination plan.

"The app that that our teams have designed is very simple, very user-friendly," Tereffe says. "It prompts you to put in your preferred contact information, both email and phone. It allows you to choose a block of time and a day that you'd like to be vaccinated. And it puts the information right there at your fingertips about the vaccine and the vaccine clinic process so that you can review it in real time."

As soon as an employee chooses an appointment slot, they receive conformation via the app. Through the app, an employee can cancel or reschedule an appointment.

"I think that level of access and control really helps to reassure people that they can trust the process," Tereffe said.

The app also gives MD Anderson more control over the vaccination clinics, according to Campbell and Tereffe. For instance, a dashboard created by IT professionals at the hospital gathers data from the app to track how many vaccinations have been given, how many appointments have been canceled, and which times and days are most popular for vaccinations. Tereffe said those real-time insights have enabled MD Anderson to adjust the operating hours for vaccination clinics.

To supplement the app, MD Anderson provides extra assistance with vaccination scheduling for employees with language or technology barriers, Tereffe said. The hospital also runs a vaccination hotline staffed by HR professionals.

Looking ahead, Tereffe said MD Anderson will accept any COVID-19 vaccine that's been approved by the U.S. Food and Drug Administration (FDA). So far, that's limited to the Pfizer and Moderna versions.

"We have a process in place to hold unique clinics for each type of vaccine and each dose of vaccine to ensure that people get the vaccine that they have chosen … and that they always get the correct second dose," Tereffe said. "Our intent is to help our employees make informed decisions."
