KEY POINTS
  • The arrival of warmer weather in combination with increasing vaccinations could help contain the virus, Scott Gottlieb told Shepard Smith.
  • The emergence of variants could complicate efforts to reopen the economy in the U.S.
  • Gottlieb said he doesn't think travel restrictions could stop the spread of the B117 variant, because often they can be too late.

An increase in vaccinations in the coming weeks in itself might not be enough to contain the spread of a coronavirus variant that was first reported in the United Kingdom in December and has now appeared in the U.S, said Scott Gottlieb, former commissioner of the Food and Drug Administration.

The emergence of variants could complicate efforts to reopen the economy in the U.S., which has faced at least 475,000 virus deaths, more than any other country, according to Johns Hopkins University data.
