Donald Trump was booed at a rally in Alabama on Saturday night after telling supporters to “get vaccinated.”

The former president was speaking in Cullman, Alabama, a city dealing with a surge of COVID-19 cases. The city also has a low vaccination rate.

Trump made comments that promoted getting vaccinated and confirmed that he himself got a jab. Many in the crowd could be heard booing and Trump did not seem to fully challenge the crowd to get vaccinated, instead he referenced their freedom.

"And you know what? I believe totally in your freedoms. I do. You've got to do what you have to do," Trump said. "But, I recommend: take the vaccines. I did it. It's good. Take the vaccines." 

Trump, who contracted COVID-19 in October, was quick to get the vaccine, reportedly receiving it in January.

“I happen to take the vaccine. If it doesn't work, you'll be the first to know. O.K.? I'll call up Alabama, I'll say, 'hey, you know what? But [the vaccine] is working.' But you do have your freedoms you have to keep. You have to maintain that," he said at the rally.

In mid-March, Trump appeared on Fox News where he called it "a safe vaccine" and "something that works."

The Alabama State Hospital Association on Saturday reported that 83% of its COVID-19 adult inpatients were unvaccinated and that 12% of the patients were vaccinated.

Alabama has the lowest vaccination rate in the U.S., with only 36% of its population vaccinated, according to NBC News tracker.

Overall, the state has reported 2,661 Covid-19 cases for adults and 40 cases for children.
