Donald Trump booed in Alabama

This isn't the first time that Trump was booed for encouraging his supporters to get vaccinated.

In August, he attended a rally in Alabama. He said that while he understands that his supporters have the right to make decisions for their bodies, he's still recommending that they get vaccinated.

Weeks later, Trump claimed that he might not opt for a third jab. He said that he's not against booster shots, but he also thinks that it's for him. Trump said that he needs to look into booster shots first before making a decision.

Donald Trump sends mixed messages about COVID-19, vaccines

According to Business Insider, Trump's mixed messages regarding the vaccine have not helped in encouraging more Republicans to get the jab.

For instance, he previously admitted that the vaccines are safe, but he also stressed that Americans shouldn't be required to get them.

In March, Trump encouraged Americans to get inoculated, but this was already after he left the White House. But Trump and his wife, Melania Trump, reportedly got vaccinated in January right before leaving the Oval Office.

Trump didn't also participate in the video that other American politicians released encouraging the public to get the jab. As such, his revelation that he had already received his booster shot might have come as a surprise to his supporters.
