To be up-to-date on COVID vaccinations, a person must have completed their primary vaccine series and received the most recently recommended booster, according to the Centers for Disease Control and Prevention (CDC). Before this proliferation of subvariants, there were complete shifts from wild-type (the original viral strain) to Alpha, Delta, Omicron and the earlier Omicron subvariants (BA.1, BA.2 and BA.5 . A recent pre-print of a forthcoming medical study organized by researchers within the University of California system contains data that further suggests immunity earned from an Omicron infection may not be as protective as immune responses recorded during the Delta wave in 2021, let alone immunity granted by a vaccine. That means you may have a shorter time of maximum protection than you thought after an infection. Ongoing studies of COVID-19 are helping us understand: How often reinfections occur Who is at higher risk of reinfection I thought I was immune at least for a while after having COVID. We won't be able to respond to every question personally, but what you share with us will help us make our coverage more useful and relevant to you and the people you know.

So people are wondering: If I had omicron once, can I get it again? What Happens After the Omicron Wave Passes? Use the CDC'sdata trackerto check your local infection and hospitalization rates. According to Robert Wachter, a professor and chair of the department of medicine at University of California, San Francisco, this is probably not an example of reinfection but something different, known as "rebound," when some patients begin experiencing symptoms and test positive again 2 to 8 days after taking the medication. And the results show just how quickly omicron can mutate and overcome the defenses our immune systems put up. According to the Centers for Disease Control and Prevention, post-COVID conditions (another name for long COVID) include a range of health problems that people may experience four or more weeks after being infected with the coronavirus. You can also reduce your risk of getting reinfected by avoiding crowded indoor places and wearing a mask indoors if Covid is spreading at a high level in your area, Horton adds. But keep in mind that certain conditions such as having had an organ transplant, ongoing cancer treatments or heart or lung disease make you more vulnerable to bad outcomes, even if you've encountered the virus before through vaccination or infection. Another reason the CDC advises against asymptomatic testing for 90 days after having COVID-19 is that if you are infected, your immune system is going to generate antibodies, so your immunity to the virus will be boosted, says Mansoor Amiji, university distinguished professor of pharmaceutical sciences and chemical engineering at Northeastern. Up-to-date means to completing your primary series and receiving the booster shots you're eligible for. "So we saw people who had alpha or delta in the past be relatively protected, but potentially get infected with omicron. A recent study from Qatar suggests previous COVID-19 infection was roughly 90 per cent effective at preventing an infection with the Alpha, Beta or Delta variants, but only 56 per cent effective against Omicron. Yes, it's possible to catch COVID after just having it. BA.4, BA.5 is the first one where we're seeing some reinfection even of people that had a prior version of omicron.

After Omicron emerged, prior infections only provided about 50 percent protection against reinfection, Dr. Abu-Raddad's study showed. Who Has the Most Robust Antibodies to Fight Omicron? Dr. Benjamin Neuman, the chief virologist at Texas A&M, warns the omicron BA.5 subvariant should not be taken lightly. Where Omicron was much more transmissible, she said. A genetic trait that harkens back to the pandemic's past, similar to what is known as the delta mutation," appears to allow the subvariants "to escape pre-existing immunity from vaccination and prior infection, especially if you were infected in the omicron wave," said Dr. Wesley Long, a pathologist at Houston Methodist in Texas. See an archive of our FAQs here. "Neutralization capacity after BA.4/5 was very low," immunologist Alex Sigal, who led one of the studies, wrote on Twitter. So that's really the focus.". Researchers led by Dr. David Ho, the director of the Aaron Diamond AIDS Research Center, took antibodies from people who received at least three doses of an mRNA vaccine or got two shots and were then infected with Omicron.

Chicago's top doctor noted that while the omicron variant itself marked a distinct shift in reinfections, evading natural immunity from infections with previous strains, BA.5 has similarly evaded immunity from even other omicron infections. hide caption. Ray agrees that chronic inflammation from COVID might play a role in diabetes risk. There is a possibility of becoming impacted by Omicron when it comes to reinfection, but there isn't enough data yet to determine how likely this would be in reality and certain trends elsewhere in the pandemic suggest that any likelihood of an Omicron reinfection for any given person may further be on the decline. If you're worried about getting sick again whether from the Omicron COVID-19 variant or from a future variant altogether the best course of action is to get vaccinated, even if you've recently fought your way through a COVID-19 sickness and have yet to be vaccinated or received a booster shot.
