Jill Biden, who is double vaccinated and twice boosted, experienced mild flu-like symptoms. She was prescribed Paxlovid and isolated at a private home on Kiawah Island, S.C., where she and President Joe Biden were vacationing.

According to Yahoo! News, Biden traveled to Rehoboth Beach, Del., on Sunday, where she is isolating again.

Alexander said the first lady had no reemergence of symptoms.

President Biden continues to test negative after twice testing positive for the coronavirus recently.

A UK study of vaccinated people who repeatedly contract Covid infections found that they could continue to be infected up to 8 times or more.

The mRNA vaccines were designed to prevent transmission of the virus by stimulating their immune systems to build immunity to the virus.

However, the UK study participants were unable to fight off COVID infections even after multiple vaccinations.

In January, CDC director Rochelle Walensky said the vaccines can’t prevent transmission of the virus anymore.

Instead, Walensky said the vaccines prevent serious illness or death.

“Our vaccines are working exceptionally well. They continue to work well for Delta with regard to severe illness and death. They prevent it. What they can’t do anymore is prevent transmission.”

The UK study participants say they are grateful for the vaccines, which they believe will continue to protect them when they are infected with COVID again.

They are wary of isolating each time they are infected with COVID. But they said they have a social responsibility to avoid passing on the virus to others.
