As Americans face a daunting surge of Covid-19 hospitalizations – with rates for children and adults under 50 hitting their highest levels yet – the US Food and Drug Administration on Monday granted full approval to the Pfizer/BioNTech Covid-19 vaccine for people 16 and older.
The approval could help allay concerns for those who are vaccine hesitant, as all three vaccines available in the US have so far been distributed under emergency use authorization.
It could also help businesses, schools and states enforce vaccine mandates, experts have said. Such mandates could help quell the ever-growing number of cases, especially in states that are experiencing a lack of available ICU beds.
“It’s an important step because it makes mandates easier, and it will address concerns of some of the people who have been on the fence about getting vaccinated,” former CDC director Tom Frieden told CNN’s Wolf Blitzer on Monday.
Some universities and employers have issued mandates, including hospital systems, and the FDA approval is already accelerating that trend. On Monday, New York Mayor Bill de Blasio announced that all education department staff in public schools across the city must be vaccinated. That makes New York the largest school system in the country to have such a mandate.
The US military also will now require all service members to be vaccinated, Pentagon spokesperson John Kirby said Monday.
And in New Jersey, all state employees must be fully vaccinated by October 18 or be subject to regular testing, Gov. Phil Murphy said Monday.
The number of vaccine doses administered daily has mostly increased over the past week – with three days surpassing a million reported doses, according to data published by the US Centers for Disease Control and Prevention. Meanwhile, the daily average of new reported cases is around 147,000, and experts have warned it could surpass 200,000 on the current trajectory.
Vaccination is key to controlling the virus
About 171 million Americans, 51.5% of the population, were fully vaccinated as of Monday, CDC data show, while 60.8% have received at least one dose. A total of 25 states have fully vaccinated more than half of their residents, with Michigan the latest state to do so, according to CDC data.
Some health experts, such as Dr. Peter Hotez, a vaccinologist and dean of the National School of Tropical Medicine at Baylor College of Medicine, say the US needs to have at least 80% of its population vaccinated to get the virus under control.
“If we’re going to halt this virus transmission, we’re going to have to get to 80-85%,” Hotez told CNN’s Jake Tapper Monday. And while the FDA approval may help convince a few people to get vaccinated, he said, mandates will be more helpful in reaching the goal.
“I think the bigger impact, as was mentioned, is going to be around mandates, employer mandates, federal mandates, from the military,” Hotez said.
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told CNN on Monday that if the majority of the population gets vaccinated, the US could regain control of the virus by the spring of 2022.
Fauci said he misspoke when he told NPR earlier on Monday that it would be the fall of 2022.
“If we can get through this winter and get really the majority – overwhelming majority – of the 90 million people who have not been vaccinated, vaccinated, I hope we can start to get some good control in the spring of 2022,” Fauci told CNN’s Anderson Cooper.
Fauci said that includes vaccinating people who have contracted and recovered from Covid-19, who could stand to gain “an enormous increase in the degree of protection,” from the vaccine.
“As we get into the spring, we could start getting back to a degree of normality, namely reassuming the things that we were hoping we could do – restaurants, theaters, that kind of thing,” he said.
Fauci said it’s not yet clear what percentage of the population needs to be vaccinated for the US to gain control over the virus.
“You know how you’re going to know? Just get as many people vaccinated as you possibly can, and when you get control, that’ll be the number,” Fauci said.
But in many states with lower vaccination rates, hospitals have been overwhelmed by a surge in Covid-19 patients.
In Mississippi, where 36.8% of the population is fully vaccinated, Gov. Tate Reeves said Sunday that a 23-person active-duty military Covid-19 response team was deployed in Jackson to provide supplemental medical staffing at hospitals. A second team is expected to arrive in Tupelo in the next week.
An uptick in cases among school-age children following the return to in-person learning has also worried health officials, with thousands of kids quarantined over the past week due to Covid-19 outbreaks. Experts have stressed that to protect those under 12 who can’t get vaccinated yet, it’s important to make sure those who are eligible get the shot. Another key prevention method is wearing a mask.
Former FDA Commissioner Scott Gottlieb told CBS’ “Face the Nation” on Sunday that warning signs for what could happen nationwide in the coming weeks have already been seen in the South.
“Schools open earlier in the South, against the backdrop of still a lot of prevalence (of Delta) and the infection is getting into schools, and it’s proving to be hard to control in schools,” Gottlieb explained. “Delta is a very contagious variant and so I think that this is a harbinger of the challenges that we’re going to face nationally as schools reopen.”
How to keep schools open and children safe
While districts continue to return to in-person learning, a debate is brewing between districts, parents and local officials on how to make the safest return to classrooms.
In Texas and Florida, governors have threatened to pull funding from districts that create mask mandates, but several local school boards are pushing back and telling students to mask up.
In Florida, nearly 20,000 students and staff members had to be quarantined after more than 6,000 covid cases were identified among the state’s 15 largest school districts since the start of school, according to a CNN analysis conducted last week. Among those, were 4,641 students and 1,547 employees who tested positive. That doesn’t include the two biggest school districts in the state, Miami-Dade and Broward.
While the number of cases has been rising amid the return to school, Gottlieb said it’s hard to assess if that is because the Delta variant itself is more aggressive in children or because we are simply exposing more kids to the virus.
He said schools should be following the lead of some districts in North Dakota, where schools are testing close contacts every few days to make sure asymptomatic cases aren’t going undiagnosed.
“Test the close contact of kids immediately to make sure there’s not other asymptomatic cases that are going undiagnosed, and then test them at some kind of interval, maybe three days and five days to make sure that there’s not an outbreak being triggered in the school,” Gottlieb told CBS.
US Surgeon General Dr. Vivek Murthy echoed the importance of keeping children safe amid the rise in pediatric cases.
“It’s our moral responsibility as a society to do everything we can to protect our children,” he told ABC’s “This Week” on Sunday. “Number one, all of us getting vaccinated as adults is important. Kids too young to get vaccinated rely on those around them to shield them from the virus.”
Vaccine boosters up for consideration
While vaccination rates still lag in the US, those who are already vaccinated are weighing the need for booster shots.
Starting September 20, those who are eight months out from their second dose of either the Moderna or Pfizer vaccine will be eligible to receive a booster, if FDA authorizes them and the CDC recommends them.
And those who received the Johnson & Johnson vaccine will also likely need a booster, according to Murthy.
“We believe that J&J recipients will likely need a booster but we are waiting on some data from the company about a second dose,” Murthy said on CNN’s “State of the Union” Sunday.
So far, only Pfizer has submitted initial booster data to the FDA; the company said Phase 3 results evaluating the third dose are expected shortly.
At the same time it’s considering boosters, the FDA has been working with Pfizer and BioNTech, Moderna, and Johnson & Johnson towards full approval – a process known as Biologics License Application or BLA.
Clarification: This story has been updated with Fauci’s clarification that the US could have control over Covid-19 entering spring 2022 if most eligible people get vaccinated.
