"The current recommended vaccines are effective at preventing serious disease for all of the omicron variants," says Schaffner, adding that it seems like they will do the same for XBB.1.16. "Its a great time for everybody to get a few of those kits at home, because if youre antigen negative, you're very likely not to be able to spread the virus and that's a good thing for people to know.". This way, they can potentially get a prescription for Paxlovid, an antiviral medication used to help prevent severe illness from the disease. Learn more about the difference between quarantine and isolation. It's becoming more and more difficult to compare new variants to old variants, because we're getting so much more immunity in the population, Andrew Pekosz, PhD, a virologist and researcher at Johns Hopkins Bloomberg School of Public Health, told Verywell. Fortunately, the pinkeye observed in people with XBB.1.16 appears to run its conventional course and resolve in about a week, says Schaffner. The study also found that the severity of Delta and Omicron hospitalizations were comparable for people admitted to the hospital, but that people with Omicron appeared less likely to be admitted to the hospital to begin with. Four doses of an mRNA vaccine has been providing excellent protection against severe disease from Omicron, but incomplete protection from acquiring infection, Weiss said.
