(CNN) – US President Joe Biden tested negative for COVID-19 on Sunday, White House deputy press secretary Karine Jean-Pierre said Monday morning.
The president took the test regardless of press secretary Jen Psaki’s positive result, which she revealed in a statement Sunday afternoon. The test was required to enter the UK, where Biden is heading to the United Nations Climate Summit, known as COP26, in Glasgow, Scotland.
Psaki said Sunday that he last saw Biden five days earlier, “when we sat outside more than six feet away and wore masks.”
The White House announced Thursday that Psaki would no longer accompany Biden on his trip abroad “at least for the first few days,” citing a family emergency. Instead, the White House undersecretary of press, Karine Jean-Pierre, traveled with the president.
Psaki is unlikely to have infected Biden with COVID-19, multiple doctors told CNN on Sunday.
“Based on the chronology of Ms. Psaki’s negative test for several days after her last meeting with President Biden (who was also outside and wearing a mask, therefore very low risk in himself), it is practically impossible that she somehow infected the president, “Dr. Leana Wen, CNN medical analyst and former Baltimore City health commissioner, told CNN.
Dr. Peter Hotez, an infectious disease expert at Baylor College of Medicine, also said he felt Biden was well protected.
“Well, he’s three times vaccinated so he should be fine, unless he has immunodeficiencies that we don’t know about,” Hotez told CNN by email.
And Dr. Jonathan Reiner, a professor of medicine at George Washington University, also pointed to the fact that the most recent interaction between Psaki and Biden had been outdoors.
“Outside transmission is much less likely than inside. Also, both she and the president were wearing masks. That would further reduce the likelihood of transmission. Also, remember, the president had received a boost. Recent data from Pfizer shows the third dose, what we’ve called a booster, restores the effectiveness of the vaccine to about 95%, so I’m sure the president will be fine too, “Reiner told CNN’s Jessica Dean.
