And no vaccine is perfect, so continuing to take precautions wearing a mask, getting tested if you have symptoms or are exposed to COVID, improving ventilation, and more is still recommended, especially during surges like the one the U.S. is currently seeing. While data is still limited around Omicron spread given that researchers need more time to confirm trends, real-world data of Omicron spread in South Africa suggests that overall immunity may be less robust following a mild COVID-19 infection, which has been the case for most Omicron sicknesses, says Sanjiv S. Shah, M.D., chief medical officer for MetroPlusHealth. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

In the studies, researchers took blood from people infected with the original omicron variant, BA.1, and looked to see if the antibodies in the blood could neutralize newer versions of omicron, including the one that emerged in New York state (BA.2.12.2) or the two variants surging in South Africa (BA.4 and BA.5). Now two preliminary studies, published online this week, start to answer that question. Paxlovid is an antiviral drug doctors prescribe to treat mild to moderate COVID-19 in people at high risk of severe illness. "If everyone got the bivalent booster that they're supposed to do, that's really the most important point.". Nevertheless, Sigal believes this decline in antibody potency is enough "to cause trouble and lead to an infection wave" like in South Africa, where only about a third of the population is immunized. Research has shown that for people .

"It appears that immunity from natural infection would generally start to wane after about 90 days, and immunity following vaccination, especially with a booster dose, will persist longer," he adds. For people not vaccinated, their antibodies ability to neutralize BA.4 and BA.5 dropped by nearly 8 times, compared to the activity against BA.1, both studies reported. Mansoor Amiji, Ph.D., chairman and professor of the pharmaceutical sciences and chemical engineering department at Northeastern University's School of Pharmacy, tells Good Housekeeping that most researchers are still working to understand how rapidly antibodies fade after an infection, specifically.
