Vice President Pence, second lady Karen Pence and Surgeon General Jerome Adams received a COVID-19 vaccine on Friday at the White House in a televised event aimed at showing the vaccine is safe and effective.

Pence, wearing a short-sleeve dress shirt, pushed up his sleeve to get the vaccine. He appeared to be smiling underneath his mask and did not watch as he was administered the vaccine by a member of the Walter Reed National Military Medical Center.

"I didn't feel a thing! Well done!" Pence said after getting the shot.

Cruise lines may begin sailing again from U.S. ports under rules released Friday by the Centers for Disease Control and Prevention. The federal agency is allowing a "No Sail" order to expire at midnight Saturday.

The Centers for Disease Control and Prevention has asked states to prepare to distribute a potential coronavirus vaccine as soon as late October, according to a series of planning documents sent to public health officials last week.

A CDC spokesperson confirmed the authenticity of the documents in an email to NPR on Wednesday. The documents were first published by The New York Times.

The Trump Administration has mandated that hospitals sidestep the Centers for Disease Control and Prevention and send critical information about COVID-19 hospitalizations and equipment to a different federal database.

From the start of the pandemic, the CDC has collected data on COVID-19 hospitalizations, availability of intensive care beds and personal protective equipment. But hospitals must now report that information to the Department of Health and Human Services, which oversees the CDC.
