There's new worry about the delta variant.

The strain was first discovered in India and is now responsible for an estimated 90% of cases in the U.K.

Former FDA commissioner Dr. Scott Gottlieb says it will likely become the most dominant strain in the U.S.

Gottlieb says the delta strain is 60% more contagious than other variants but he says so far, vaccines are effective in protecting against it.
