The Omicron XBB.1.5 variant of COVID-19 is more likely to infect individuals who have been vaccinated, as well as those with natural immunity, according to New York City health officials.
“Omicron subvariant XBB.1.5 now accounts for 73 percent of all sequenced COVID-19 cases in NYC. XBB.1.5 is the most transmissible form of COVID-19 that we know of to date and may be more likely to infect people who have been vaccinated or already had COVID-19,” the NYC Department of Health and Mental Hygiene wrote on Twitter on Jan. 13.
