President Donald Trump appeared to zone out during an Oval Office announcement on vaccines, prompting a fresh round of mockery online.

On Monday, Trump signed an executive order that calls for reducing the number of vaccines recommended for children and splitting the MMR shot — which protects against measles, mumps and rubella — into three individual vaccines.

The order is the latest step in the administration’s campaign to remake the childhood vaccination schedule, led by Health and Human Services Secretary Robert F. Kennedy Jr., who has long questioned vaccine safety.

During the ceremony, the 80-year-old president appeared to repeatedly close his eyes while seated behind the Resolute Desk — including as Kennedy and National Institutes of Health Director Jay Bhattacharya spoke beside him.

Videos of the moments quickly circulated on social media.

“I love how he pops out of it for a few seconds then closes his eyes again and he's right back in dream land. This is getting ridiculous,” wrote one X user. Another chimed in: “Why doesn't the assembled media speak out about this...they all see it.”

“What a loser,” a third user wrote. “After years of listening to those ‘sleepy joe’ comments…” The remark referred to Trump’s longtime nickname for former President Joe Biden, whom he repeatedly accused of being mentally and physically unfit for office.

Some commenters, however, were more supportive of the president. “In Trump's defense, good Lord, the speaker is boring,” one wrote.

Trump, the oldest person ever inaugurated as president, has faced persistent scrutiny over his health since returning to the White House, including over moments during official events in which he has appeared to close his eyes for extended periods. One such moment came during Lindsey Graham’s funeral last month.

“The president has severe daytime somnolence,” CNN medical analyst Dr. Jonathan Reiner said in May. “He falls asleep very often. He’s fallen asleep in the Oval Office on multiple occasions with people talking to him, in the cabinet room,” he said. “And chronic insomnia is a severe illness. It can result in an increase in risk of dementia, a decrease in cognitive effects in older people.”

The White House, meanwhile, has forcefully rejected such claims.

“President Trump is the sharpest, most accessible, and energetic president in American history and any so-called medical professionals engaging in armchair diagnosis or false speculation for political purposes are clearly breaking the Hippocratic Oath they’ve sworn to,” a White House spokesperson told The Independent at the time.

Trump, for his part, has repeatedly insisted that he is in excellent health. After a physical at Walter Reed in May, the president wrote on Truth Social that “everything” had “checked out PERFECTLY.”

In a YouGov survey conducted last year, 78 percent of respondents said they believed Trump had not been transparent about his physical health.

The Independent has contacted the White House for comment.
