Experts don't yet know if it's more contagious or if it will respond to the Pfizer or Moderna vaccines.
A new mutated COVID-19 strain is now sweeping California. It’s being linked to the Christmas costume outbreak at the Kaiser Permanente Medical Center in San Jose, California, where 90 people were infected after a staff member wore an inflatable costume.
There is growing alarm with the new strain now popping up in a dozen counties in the state. Experts don't yet know if it's more contagious or if it will respond to the Pfizer or Moderna vaccines.
Dr. Anthony Fauci is also warning of a more dangerous COVID-19 strain spreading across the globe.
“There’s another, more ominous one in South Africa and Brazil. We're looking at that very carefully,” Fauci said.
