President Donald Trump has received updated flu and COVID-19 booster shots in preparation for upcoming travel, the president’s physician announced Oct. 10.

Sean P. Barbabella, a U.S. Navy captain, shared the information in a letter submitted Friday to White House press secretary Karoline Leavitt.

“President Donald J. Trump successfully completed a scheduled follow-up evaluation today at Walter Reed National Military Medical Center,” Barbabella wrote, saying the visit was part of the president’s ongoing health maintenance plan and included “advanced imaging, lab testing and preventative assessments.”

Last month, Trump demanded that COVID-19 vaccine makers provide proof of their effectiveness.

"Many people think they are a miracle that saved Millions of lives. Others disagree!" he said of COVID-19 medications such as vaccines made by Pfizer, Moderna and other pharmaceutical firms. "With CDC being ripped apart over this question, I want the answer, and I want it NOW."
