Pfizer said Wednesday that final results from late-stage trials of the vaccine candidate it developed with BioNTech showed an efficacy rate of 95%. It plans to apply to the Food and Drug Administration “within days” for emergency-use authorization.
The drugmaker said the efficacy was consistent across age, gender, race and ethnicity dynamics, and over 94% effective in adults over 65 years old. Pfizer said there were no serious safety concerns with the vaccine.
The announcement comes two days after Moderna announced that preliminary data from its vaccine candidate showed 94.5% effectiveness. Dr. Anthony Fauci said, of the Moderna news: “I’d said I would be satisfied with a 70, 75% efficacy, that something like 95% was really aspirational … Well, our aspirations have been met, and that is really very good news.”

Despite the pandemic, the North American Aerospace Defense Command will still track Santa Claus’ progress around the globe as he delivers gifts on Dec. 24 as per tradition.
But instead of around 150 volunteers crowded into a room at Peterson Air Force Base in Colorado Springs to field calls from curious children, there will be fewer than 10 people per shift, the AP reported.
“We understand this is a time-honored tradition, and we know undoubtedly there is going to be some disappointment,” said NORAD spokesman Preston Schlachter. “But we’re trying to keep it safe for everyone involved.”

The FDA on Tuesday gave emergency approval to Lucira Health’s coronavirus rapid test kit, which can be used entirely at home and delivers results in 30 minutes. The test will require a prescription for use, however.
The approval represents a step forward in expanding testing beyond health care facilities and testing sites, which have delivered slow results in some areas across the country due to laboratory bottlenecks.
The FDA has been very cautious about approving an at-home use test because of concerns over whether people without medical training can properly test themselves and interpret the results. Read more

Sen. Chuck Grassley (R-Iowa) has tested positive for the coronavirus, making him the latest congressional lawmaker to be diagnosed with the virus.
Grassley, 87, said on Twitter that he is “feeling good” and will quarantine at home.
A new study suggests that people who recover from COVID-19 may be protected from the coronavirus for years — a much more optimistic possibility than researchers had previously thought.
Although the study has not yet been peer-reviewed or published in an academic journal, The New York Times labeled it the most comprehensive analysis of COVID-19 immunity to date. A group of researchers from California’s La Jolla Institute of Immunology, among other institutions, found that most of the patients studied had enough antibodies in their system to fight off the virus eight months after infection. That slow rate of decline indicates the antibodies may stick around for several years.
Previous research suggested that coronavirus antibodies offer people protection for three to four months after infection.

The governors of Ohio and Maryland announced Tuesday that they’re enforcing a curfew in their states to help curb the spread of COVID-19 without shutting down more businesses.
Both states’ curfews will start at 10 p.m. and have exceptions for essential workers, emergencies and other “common sense” situations, as Ohio Gov. Mike DeWine (R) said.
Maryland Gov. Larry Hogan (R) said people need a wake-up call. “This virus has been with us for so long that too many of us have become numb to staggering spiking numbers that are being announced every day,” he said.

A new statistic illustrates North Dakota’s alarming coronavirus reality: One out of every 1,000 residents across the state has died of coronavirus, as first reported by Bloomberg’s Steven Dennis.
With a population of around 760,000, according to the Census Bureau, North Dakota is among the least dense states in the country. But the virus has still managed to spread like wildfire, prompting Gov. Doug Burgum (R) to issue a mask mandate for the first time late Friday night. The state has recorded nearly 65,000 cases of the virus, which represents around 8.5% of North Dakotans, according to data compiled by Johns Hopkins University.

Iowa’s Republican governor, Kim Reynolds, has completely changed her stance on mask use as cases surge across her state. Back in July, she said that she had no intention of requiring masks in public spaces, claiming there was “no way to enforce it” and that they are “just kind of a feel-good” tool.
“Our health care system is being pushed to the brink,” Reynolds said Monday evening, noting that one in four hospitalized patients now has the virus. Everyone in Iowa over age 2 will be required to wear a mask in indoor public spaces beginning Tuesday, and indoor events will be capped at 15 people. The state recorded 83,000 new cases in the last month, with almost 30,000 of those coming in the past week.
“If our health care system exceeds capacity, it’s not just COVID-19 we’ll be fighting. Every Iowan who needs medical care will be put at risk,” she explained. “If an ambulance is transferring a COVID-19 patient, it may not be available to respond to an accident on a rural county road. If hospital beds are full, a loved one who suffers a heart attack or a stroke may have to be transported miles away to receive life-saving treatment.”
Reynolds said her family is postponing Thanksgiving celebrations this year in the name of safety and encouraged others to do the same, adding: “No one wants to do this. I don’t want to do this.”
“This isn’t about mandates. This isn’t about government,” she said. “If Iowans don’t buy into this, we’ll lose.”

Iowa Sen. Chuck Grassley (R) said that he has been exposed to the coronavirus and will begin quarantining at his home as he awaits test results. Grassley is 87 years old; the Centers for Disease Control and Prevention has said that Americans aged 85 or older face the greatest risk of severe illness from the virus.
In a statement, Grassley said he is “feeling well and not currently facing any symptoms.”

The city of Philadephia on Monday ordered a ban on “indoor gatherings of any size in any location,” except among individuals who live together, from Friday until the new year, in one of the toughest coronavirus restrictions imposed across the country.
“While we won’t prohibit people from leaving home and interacting, we want to strongly discourage that, because it’s increasingly unsafe to interact with anyone,” said Philadelphia Health Commissioner Thomas Farley. “We know that’s a very strong policy, but this gets at the most important sites of spread.”
As the U.S. surpassed 11 million COVID-19 cases, New Jersey, California and Ohio ordered new restrictions. New Jersey ordered lower limits on indoor and outdoor gatherings while California banned indoor service in bars and restaurants in most counties.

California Gov. Gavin Newsom on Monday announced an indefinite “emergency brake” to the state’s reopening process in response to rising COVID-19 cases.
Starting Tuesday, 28 counties will be rolled back to the most restrictive “purple” tier, which means most nonessential businesses will be closed, the Democratic governor said during a press conference. Nine more counties will be rolled back the second-most restrictive “red” tier, meaning some businesses will be allowed to stay open.
The new rollbacks put 94% of California’s population in the most restrictive tier, state officials said. The status of counties now in more restrictive tiers will be assessed daily instead of weekly, and the rules will stay in effect until California’s public health director says that conditions have improved in the state.
The announcement comes amid California’s steepest rise yet in COVID-19 cases. Over the seven-day period ending Sunday, the state averaged 7,985 cases per day, an 89.7% increase from two weeks ago.
“We are sounding the alarm,” Newsom said in a statement. “California is experiencing the fastest increase in cases we have seen yet — faster than what we experienced at the outset of the pandemic or even this summer.”

Multiple members of Congress announced they are self-isolating after exposure to the coronavirus.
Rep. Tim Walberg (R-Mich.) said he tested positive Sunday for the virus. “I received news yesterday that I tested positive for COVID-19,” Walberg said in a statement. “My symptoms are mild and I remain in good spirits.” The congressman urged everyone to adhere to public health guidelines and said he will work from home for the foreseeable future.
Reps. Mark Pocan (D-Wis.) and Debbie Lesko (R-Ariz.) said they too are in isolation after separately being exposed to people with the coronavirus. According to reports, Pocan learned of his exposure to the virus last Tuesday after driving his mother, who later got a positive test result, to her nursing home.
“Fortunately, the nursing home staff contacted me immediately after learning of my mother’s positive result and I was able to quarantine without delay,” Pocan said in a statement. “Unfortunately, too many people in Wisconsin don’t get that information in a timely way due to the low number of contract tracers we have hired in Wisconsin.”
In a statement, Lesko said she was in contact with someone “late last week” who has since tested positive for the virus. “At this time, I am not experiencing symptoms,” she announced, adding that she will begin a 14-day quarantine and conduct business from home.

Dr. Anthony Fauci, the top infectious disease expert on the White House’s coronavirus task force, applauded early data from biotechnology company Moderna and pharmaceutical company Pfizer that show their respective coronavirus vaccines are highly effective.
“The data are striking,” Fauci told NBC’s “Today” about the Moderna data, released earlier Monday. “They’re really quite impressive. … Now we have two vaccines that are really quite effective. So I think this is a really strong step forward to where we want to be about getting control of this outbreak.”
Fauci said he expects the Food and Drug Administration to grant emergency use authorizations for the vaccines. “Doses could be available to high-risk individuals by the end of December,” he told NBC.
