Is it time to rethink what we know about COVID-19 reinfection?

Forget what you thought you knew about catching COVID-19 more than once. SARS-CoV-2, the virus that causes COVID-19, keeps evolving – and so has information about your risk of being reinfected.
“Two years ago, we thought if you had COVID once that you would never get it again,” said Dr. Preeti Malani, an infectious disease physician at the University of Michigan in Ann Arbor. But especially with the variants that have become dominant in the U.S. this summer, that thinking no longer holds.
When it emerged last November, the omicron variant of SARS-CoV-2 showed an ability to reinfect people who’d had earlier versions of the virus. This summer, according to the Centers for Disease Control and Prevention, the omicron subvariants BA.4 and BA.5 are sweeping the U.S., with BA.5 accounting for the majority of COVID cases. Both appear to be even more adept than other omicron subvariants at evading the body’s defenses against infection.
Even having had an earlier version of omicron does not seem to protect against symptomatic infection from the BA.4 and BA.5 subvariants, Malani said. The subvariants also can infect vaccinated people.
“I have friends who have had COVID three times,” said Malani, who has co-written an ongoing series of updates about the virus for JAMA. “One of my kids had it twice.” And Malani herself recently tested positive for the first time, despite being up-to-date on her vaccinations.
The good news is that despite spreading more easily, the subvariants do not appear to cause more severe disease. And vaccination still protects against severe illness, especially hospitalizations and death.

More good news: A new, more traditional vaccine is available. More than one out of five Americans still have not gotten a shot.
Meanwhile, President Joe Biden tested positive for COVID-19 on Thursday and went into isolation with mild symptoms. White House officials went all-out to show that the 79-year-old U.S. leader could power through the virus and keep working because he was vaccinated and boosted.

Biden is reporting a runny nose, fatigue and an occasional dry cough, according to a memo from Dr. Kevin O’Connor, the president’s doctor. Biden felt tired Wednesday evening and didn’t sleep well, White House COVID-19 coordinator Dr. Ashish Jha said at a press briefing. Biden tweeted Thursday: “Folks, I’m doing great. Thanks for your concern.”

Biden is routinely screened for coronavirus. His infection was detected first with an antigen test, the same type that many Americans use at home. It was then confirmed with a PCR test, the president's doctor said. The president’s last previous test for COVID-19 was Tuesday, when he had a negative test result.

Yes. The president is fully vaccinated and twice boosted. Biden got two doses of the Pfizer vaccine shortly before taking office, a first booster shot in September and an additional dose March 30.

White House Covid Response Coordinator Ashish Jha speaks about President Joe Biden's positive COVID-19 test during a briefing at the White House, Thursday, July 21, 2022, in Washington.
Biden is taking Paxlovid, which was authorized in the U.S. late last year. In older people and other high-risk patients, the drug was shown to reduce the chances of hospitalization or death from COVID-19. The pills work best if taken within five days of the start of symptoms. The president’s doctor said Biden's vaccination status and early treatment with Paxlovid should keep him out of danger. Biden has temporarily stopped taking a blood thinner and a cholesterol drug as recommended for patients on Paxlovid.

The memo from the Physician to the President Dr. Kevin O'Connor to White House press secretary Karine Jean-Pierre, photographed Thursday, July 21, 2022, announcing that President Joe Biden has tested positive for COVID-19.
Biden will work in isolation for at least five days and until he tests negative, the White House said. Once he tests negative, he will return to in-person work. The White House said it will provide a daily update on the president’s status.
At age 79, Biden is in a high-risk group for severe illness. About 8 in 10 COVID-19 deaths occur in people over age 65, with risk increasing with age. Also among the most vulnerable are those with other health issues such as diabetes and heart conditions.

It’s unclear which variant Biden has contracted, though a sample has been sent for genetic sequencing to determine that. The dominant virus variant in the U.S. is the omicron mutant BA.5, which is also prominent worldwide. The variant accounted for three-quarters of new infections reported in the U.S. last week. It’s also been gaining ground globally, making up more than half of sequenced omicron cases. Experts say BA.5 is one of the most transmissible variants yet but they haven’t seen an increase in severity compared with previous omicron variants.

That's unclear. Symptoms can start two days to two weeks after exposure to the virus. Biden has kept a busy travel schedule lately. During his recent Middle East trip, the president was seen fist-bumping, handshaking and even occasionally hugging. He returned to Washington late Saturday and kept a low profile for the next three days, leaving briefly to attend church and for a Tuesday appearance outside the White House with Ukraine's first lady. He traveled to Massachusetts on Wednesday to announce modest new steps to combat climate change.
