Dr. Jen Caudle discusses spread of new coronavirus strain

WATCH: A new strain of the novel coronavirus is raising questions about whether more vaccines or drugs will be necessary to protect against infection. Rowan University School of Osteopathic Medicine's Dr. Jen Caudle told Fox 29, "we just don't know yet." 

"There's still a lot of investigation to do," said Caudle, associate professor of family medicine. "If scientists determine something needs to be done, it needs to be done soon ... it's probably here."
