CDC Says It’s Monitoring a New COVID Variant Known as “XBB” – Deemed ‘Most Vaccine Resistant Strain Ever’
On Friday, the Centers for Disease Control and Prevention (CDC) announced that it is monitoring a new COVID-19 variant known as “XBB,” which is responsible for an estimated 3.1% of all new infections in the United States, according to Yahoo News.
Back in October, health officials in the US said they were tracking a new Covid strain that is being called the “most vaccine-resistant ever” after causing a surge in cases in Singapore.
“Preliminary research suggests the Omicron subvariant XBB might carry a higher infection risk and be more resistant to neutralizing antibodies from booster vaccine doses and antibody drugs, but more studies are needed, according to Verywell Health.
