Stephen Griffin, a virologist at the University of Leeds School of Medicine, believes BA.1, BA.2 and a third Omicron sub-variant that never took off, evolved over the course of chronic infections in a small population of immune-compromised people, before spreading across the globe. Exactly how common Omicron reinfection is remains to be seen, given that this is still a fairly new COVID-19 variant, Dr. Russo says. 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.

It found only 91 people who had Delta than caught Omicron - just 0.16%. A fully vaccinated person who had a breakthrough infection is best protected against future infection, a recent CDC study found. These include the BA.2, BA.4, and BA.5 variants.

When looking at the state of COVID-19 in the United States, Mansoor Amiji, distinguished professor in the Department of Pharmaceutical Sciences at Northeastern, invites you to think from the perspective of a virus. 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. However, the BA.2 variant is less likely to reinfect those who have already contracted the BA.1 variant. There is still very much potential for new variants to arise this season and later this year, Amiji adds, as the majority of nations still have vaccine access issues and populations that are under-vaccinated, an issue that WHO officials have repeatedly called attention to.
