See vaccinated Americans' handwritten notes of solidarity

(CNN)Dr. Anthony Fauci said he hopes children and teens won’t hesitate when the US Food and Drug Administration authorizes a coronavirus vaccine for them.

A federal government official told CNN on Monday that the FDA is poised to authorize Pfizer/BioNTech’s Covid-19 vaccine in children and teens 12 to 15 years old by early next week, and administration of the vaccine to them could start almost immediately, said Fauci, the director of the National Institute of Allergy and Infectious Diseases.
“You have the capability of protecting yourself as a young person, 12 to 15, but also knowing that you’re not going to pass it on to someone else,” Fauci told CNN’s Wolf Blitzer on Tuesday.

“You even want to call upon the young people to say, ‘I want to protect myself, but I want to be part of the solution, not part of the problem.'”

“It has a good safety profile, and it’s highly efficacious,” Fauci said. “That’s something that you shouldn’t walk away from.”

“That will immediately add millions of more people eligible for vaccination. I bet a lot of those kids will get vaccinated,” Dr. Ashish Jha, dean of the Brown University School of Health, told CNN. “That will make a big difference as well in terms of building up population immunity.”
Pfizer and Moderna are testing their vaccines in children as young as 6 months old and expect to ask the FDA for EUAs covering infants and children later this year.

Lack of herd immunity may mean another virus surge, experts say

As health experts point to the challenges the nation faces in reaching herd immunity, some are warning of the danger of not getting there: another surge of coronavirus this winter.
Vaccine expert Dr. Paul Offit reckons that 80% of the population needs to be immune to the virus in order to prevent that scenario.
“The proof will be in the pudding next winter,” Offit told CNN’s Jake Tapper. “If we don’t get there to 80%, then I think you’ll see another surge of this virus next winter.”
Offit, the director of the Vaccine Education Center at Children’s Hospital of Philadelphia and a member of the FDA’s vaccine advisory committee, said immunity could be achieved through a combination of vaccinations and natural infections.

His warning echoed that of CNN medical adviser Dr. Leana Wen, who earlier this week said that she is worried that we may not reach herd immunity by the fall.
“And then with the winter … we have a big resurgence, maybe we have variants coming in from other countries, and we could start this whole process all over again and have another huge pandemic come the winter.”
Experts estimate that between 70% to 85% of the US population needs to be immune to the virus — through vaccination or previous infection — to control its spread. And with the number of people who are still reluctant to be vaccinated, “I’m not sure that we are going to reach herd immunity,” Wen told CNN.
There are a number of factors that suggest the odds are indeed long, said Lauren Ancel Meyers, the director of the Covid-19 Modeling Consortium at the University of Texas at Austin.

Those include that the virus spreads too rapidly, more transmissible variants threaten to make the vaccines less effective, children aren’t yet vaccinated and about a quarter of the population is hesitant or refuses to get vaccinated.
Even without herd immunity, if the number of new cases drops enough, the country could get back to something close to normalcy, some experts say.
“We may not get to zero. We probably won’t,” Jha told CNN’s “New Day” on Monday. “But if we can get the infections at very low levels, most of us can get back to our lives in normal ways. I think we can probably live with that.”
More than 44% of the total US population has gotten at least one vaccine dose and nearly 32% is fully vaccinated, CDC data shows.

FDA to consider vaccine for children as young as 2

The US Food and Drug Administration will consider within months emergency use authorization of the Pfizer/BioNTech’s coronavirus vaccine in children 2 to 11 years old — at a time polls show younger Americans are least likely to say they want a shot.
The move comes as the country’s daily Covid-19 cases and deaths are now about one-fifth of what they were during their winter peaks — and one expert says the country’s improved numbers have a lot to do with the climbing vaccinations.
Pfizer expects to submit for emergency use authorization for its vaccine for children ages 2 to 11 years old in September, the company said during its first-quarter earnings teleconference on Tuesday.
The pediatric safety and efficacy study in children age 6 months to 11 years old is ongoing.
“We expect to have definitive readouts and submit for an EUA for two cohorts, including children age 2-5 years of age and 5-11 years of age, in September,” Pfizer CEO Alert Bourla said in prepared remarks. The readout and submission for children 6 months to 2 years is expected in the fourth quarter of 2021, he said.
Bourla said the company expects to hear back shortly on its application for extended EUA for the vaccine to include 12- to 15-year-olds.
Phase 2 safety data from Pfizer’s ongoing study in pregnant women is expected by late July or early August, Bourla said Tuesday.
It’s critical that younger Americans get a shot as well, experts say, for both their own protection and to help the country reach widespread protection.

White House announces new vaccination goals

President Joe Biden, during remarks at the White House, on Tuesday officially announced a new vaccination goal, saying he hopes 70% of adult Americans will have received at least one shot and 160 million Americans will be fully vaccinated by July 4th.

“That means giving close to 100 million shots, some first shots, others second shots, over the next 60 days,” Biden said.
Addressing populations reluctant to get vaccinated, Biden noted that two vaccines were authorized under a Republican administration and a Democratic one “is doing the work to get hundreds of millions of shots in arms.”
“While we may not always agree on everything, this is one thing people across the political spectrum can agree on,” he said.

Challenge now is getting younger people vaccinated

The weekly average of daily Covid-19 deaths is more than 660, according to Johns Hopkins University data. In mid-January, that seven-day average was roughly 3,400 deaths daily.
And the country has averaged more than 49,400 new Covid-19 cases daily in the past week, according to Johns Hopkins. On January 8, the country averaged more than 251,000 cases every day — the highest seven-day average of the pandemic.
So health and state leaders have turned their focus on younger Americans.

Nearly 83% of Americans 65 and older have received at least one vaccine dose and nearly 70% are fully vaccinated, according to data from the Centers for Disease Control and Prevention.
“This pandemic now is really among young people and it is a very dangerous time to be unvaccinated in the country because it is spreading pretty efficiently among young people and unvaccinated people,” Jha said.
CDC Director Dr. Rochelle Walensky warned last month the country was seeing an increase in cases and hospitalizations, predominantly among younger unvaccinated adults. And in Michigan, which battled a violent spring surge, hospitals saw more younger Covid-19 patients than ever before.
So it’s critical that younger Americans get a shot as well, experts say, for both their own protection and to help the country reach widespread protection.

Florida school district eliminates mask mandate

Florida’s Santa Rosa County school district board voted Monday to remove its mask mandate for all schools. Effective immediately, the change means face masks will be recommended but no longer required.
The decision came during a contentious special meeting where community members and parents expressed concerns over children being required to wear masks. One person described it as “terrifying to our children.”

“Let’s have some common sense, and let’s just put this away and just resume normalcy, please,” one parent said to a round of applause.
Board Chairperson Wei Ueberschaer was met with loud booing as she expressed her disappointment with the decision.
“I am truly sad that face masks have morphed from a protective strategy to a political issue,” Ueberschaer said.
The district’s decision came the same day that Gov. Ron DeSantis signed a bill and two executive orders limiting Covid-19 restrictions that counties and cities can impose.
The Florida Department of Education said the order effective immediately “only impacts city and county governments, and does NOT impact school districts and individual schools.”
Miami-Dade County Public Schools, the fourth largest district in the country, said it would keep its mask mandate in place. Palm Beach County schools is also keeping its mask mandate. If a student doesn’t comply with the district’s policy, the student may be assigned to remote learning, according to the district’s Covid-19 protocols.

Pfizer vaccine distribution may become easier

Pfizer has also submitted information to the FDA that may allow its vaccine to be stored at standard refrigerator temperatures, its CEO said Tuesday. Such a change could help simplify the distribution of the vaccine.
Bourla said the company submitted new data to the FDA on Friday, and it may “soon” have an emergency use authorization to allow standard refrigeration for up to four weeks.

Currently, Pfizer’s vaccine is authorized to be stored at ultracold temperatures, between -80 and -60 degrees Celsius, or in cold storage, between -25 and -15 degrees Celsius, for a maximum of two weeks, which can complicate distribution of the vaccine.
New data could allow the vaccine to be stored at standard temperatures, between 2 and 8 degrees Celsius, for up to four weeks, according to Bourla.
