WASHINGTON — Commissioner Stephen Hahn says Thursday's meeting of the Food and Drug Administration's vaccine advisory panel is "an important day for all of America."

The FDA head hopes it will lead to the beginning of the end of the pandemic and a return "to a more normal and healthy life."

Hahn says the FDA is working to understand the allergic reactions that turned up when the United Kingdom began vaccinations this week and that FDA would include recommendations in any emergency use authorization as to who should and should not get the vaccine. Hahn, addressing public skepticism of the vaccine, says if one authorized, it's important for people to get vaccinated to arrive at herd immunity.

He says: "I have 100% confidence, and I think the American public should as well, with respect to our review of the safety and efficacy of vaccine."

He spoke Thursday morning to ABC, CBS and NBC.
