A new strain deriving from the Delta Variant was discovered in the United Kingdom and raised concern as it appeared to rapidly spread. It make up for a good amount of newly reported cases when first discovered.
Now, AY.4.2 has been found in the U.S. While concerning for scientists, Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, said it hasn’t been linked to any clusters.
She added that at this time there’s nothing to raise concern that the variant is any harder to handle with the current vaccines.
Dr. Scott Gottlieb, who is the former commissioner of the FDA, would like to see more research into the strain. One of his biggest questions is whether it is in fact more transmissible.
