The Vaccines and Related Biological Products Advisory Committee, an independent panel of infectious disease experts, doctors and scientists, is meeting Thursday to recommend if the Pfizer vaccine should be considered safe and effective in the U.S.

Food and Drug Administration Commissioner Stephen Hahn told “Good Morning America” Thursday that he wouldn’t “prejudge” what the advisory committee would vote, but said the FDA will act “quickly” afterward.

“FDA's reviewers are mothers, fathers, brothers, sisters. We totally understand the urgency of this situation, and we are working around the clock on behalf of America,” Hahn said. “FDA scientists are known around the world for their expertise. We are a regulatory gold standard for the authorization or approval of medical products, including vaccines. We intend to do and we have done a very thorough review to get this right, to get all the answers we possibly can from the data.”

Hahn also said the FDA was “working very closely with our U.K. partners” after two people who received the vaccine in the U.K. had severe allergic reactions.

Hahn told NBC that it was “possible” that the FDA could advise people with significant allergies to not get the vaccine.

Hahn said the allergy issue would be discussed at Thursday’s meeting but added that the FDA stands by “our initial assessment” that Pfizer’s vaccine “does meet our criteria.”

Just as the U.S. surpassed 280,000 deaths from coronavirus on Saturday, Dec. 5, the country is likely to pass 290,000 deaths later today.

The current death toll stands at 289,373, according to the latest data compiled by Johns Hopkins University.

This comes on the heels of new records reported yesterday in highest single-day total and seven-day average of new daily deaths -- 3,054 and 2,276 respectively -- according to The COVID Tracking Project.

Four Georgia sheriffs just elected to their counties have tested positive for COVID-19.

In a joint statement sent out Wednesday night, Fulton County Sheriff-elect Pat Labat and Cobb County Sheriff-elect Craig Owens said they tested positive after attending a sheriff’s school in Pine Mountain, Georgia.

Gwinnett Sheriff-elect Keybo Taylor and Henry County Sheriff-elect Reginald Scandrett also said they tested positive for COVID-19.

Others who attended the conference are quarantining in their homes as they await their COVID-19 test results.

“We urge all Georgians to follow the advice of our dedicated health care workers and to wear masks and socially distance," the sheriffs said in a joint statement. "While the vaccine is forthcoming, the pandemic is not over yet, and we must all remain diligent to ensure the safety of our communities."

The COVID Tracking Project reported Wednesday that 3,054 Americans died the previous day from the coronavirus, setting a new daily record.

The seven-day average of new daily deaths (2,276) also set a record, according to the health data.

"The 7-day average for COVID-19 deaths are at an all-time high as deaths are rising throughout the country. The previous single-day record was on May 7 at 2,769 deaths," the tracking project tweeted.

Daily hospitalizations also continued to set records as 106,688 Americans are currently hospitalized, according to the data. The seven-day average of hospitalizations was 102,580, another record.

Over 209,000 new coronavirus cases were reported on Wednesday, according to the tracking project.

"[California] reported a new single-day case record at 30,851. This is the second-highest case count since 12/6," the tracking project tweeted.

Common questions surrounding the newly authorized Pfizer vaccine include safety for teenagers and the risk of allergic reactions.

Though the final data doesn’t have conclusive data on 16 and 17 year olds because they weren’t enrolled in trials until more recently, the FDA is “very comfortable with the safety profile that was observed in 17 and 16 year olds," Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, told reporters.

Regarding allergies, Marks said 1.6% of the population has had a severe allergic reaction.

Marks said you should notify your doctor if you’ve ever had an allergic reaction to a vaccine and noted that sites that administer the vaccine will have medications on hand to respond to an allergic reaction.
