According to the CDC, Omicron’s BA.5 sub-variant is now the dominant strain of the virus and accounts for nearly half of infections nationwide.
Dr. Purvi Parikh, an immunologist with NYU Langone Health, said earlier this week that the BA.5 appears to be less dangerous than previous variants but is more resistant to vaccines.
"We are seeing more cases of re-infection, we are also seeing the need sometimes for multiple rounds of Paxlovid or other treatments, so you know it is concerning. We have to keep an eye on it."
