WASHINGTON, July 20 (France 24) - A vaccinated White House official has tested positive for Covid-19, a spokeswoman said Tuesday, adding that the person had not had contact with President Joe Biden or other top-level staff.
"I want to confirm that yesterday a fully vaccinated White House official tested positive for Covid-19 off campus," Biden's press secretary Jen Psaki said at a briefing, adding that the official, who has not been identified, had mild symptoms.
She said that in accordance with "rigorous" protocols, the official is staying away from the White House pending more testing, and that contact tracing had been carried out.
Psaki said there had been other breakthrough cases at the White House, but did not confirm how many or when.
"We know that there will be breakthrough cases," Psaki told reporters at the White House briefing.
"But as this incident shows, cases in vaccinated individuals are typically mild. The White House is prepared for breakthrough cases with regular testing."
She said the Covid case was "another reminder of the efficacy of the Covid-19 vaccines against severe illness or hospitalization."
Across town, the office of House Speaker Nancy Pelosi confirmed that one of her senior spokespeople had tested positive, after meeting with Democratic state lawmakers from Texas who had been in the US capital.
The individual had no contact with Pelosi, who comes after the vice president in the presidential line of succession, since being exposed, Pelosi's deputy chief of staff Drew Hammill said in a statement.
After making enormous progress against the pandemic, the vaccination campaign in the United States has stalled in recent weeks.
About 68 percent of adults have received at least a first dose, but there are large geographical disparities.
Opposition to the vaccine is significantly tied to the political divide in the country, with hostility much more pronounced among conservatives, particularly among supporters of former president Donald Trump.
