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, while data on the effectiveness of booster vaccines that target the Beta protein spike is still limited, the Moderna booster vaccines appear to be more effective. They are the best protection against Omicron, with boosters shown to be up to 80 per cent effective against hospitalisation in the weeks following.

Exactly how common Omicron reinfection is remains to be seen, given that this is still a fairly new COVID-19 variant, Dr. Russo says. "It's speculative, but if there is any potential infection that poses a comeback risk, it will be a different variant in total future variants may have the potential to be more virulent than what we have had in the past," Amiji says.
