More calls to get vaccinated against both the flu and the coronavirus.
Health experts are renewing the urgent call to get vaccinated as a new version of COVID spreads.
It appears to move faster than the highly contagious delta variant.
It first popped up in the U.K. over the summer and makes up eleven-percent of cases there.
But now it's showing up in Nevada, Florida, Maryland, Massachusetts, North Carolina, Rhode Island, Washington, and D.C.
Experts confirm delta is still the dominant strain but warn it's evolving.
