Alabama, which had the second worst case rate, reported the highest number of new Covid-19 vaccinations per capita in the country in the past week.
Other states that are reporting some of the country’s worst case rates but high numbers of new vaccinations include Florida, Georgia, Kentucky, Mississippi, and South Carolina.
“We are optimistic in that we feel that number is going to continue to go down, but it’s important to understand our hospitals and ICUs continue to be at very tight capacity,” Dr. Victor Herrera, the chief medical officer at AdventHealth Orlando said in a briefing. “It’s going to be some time before we really feel that relief.”
Covid-19 hospitalizations remain high, but there are signs of improvement, HHS data show
Covid-19 hospitalizations in the US have been rising steadily since early July, but are starting to show signs of improvement, HHS data shows.
Total hospitalizations nearly tripled in July and doubled again in August, according to HHS data, and for the past eight Sundays, total hospitalizations were an average of 25% higher than the week before.
But over the past seven days, total hospitalizations in the US grew by only 2%. In fact, there were 134 fewer new admissions during the week of August 24 than there were during the previous week.
But hospitalizations remain perilously high; there are currently 102,804 people hospitalized for Covid-19 in the United States, 72% of the way to the peak from mid-January, according to HHS data. Overall, hospitals across the country are nearly three-quarters full and ICUs are about 80% fully.
Fauci: 3 vaccine doses likely needed for full protection
It’s likely that three doses of the Moderna or Pfizer Covid-19 vaccine will end up being the recommended full dose regimen for protecting people from infection, Dr. Anthony Fauci said Thursday, but noted it’s up to the US Food and Drug Administration to decide whether Americans should get three doses of the vaccine.
The agency will consider the question later this month. Moderna and Pfizer have both applied for FDA authorization for a third dose either six months or eight months after the second dose.
“From my own experience as an immunologist, I would not at all be surprised that the adequate full regimen for vaccination will likely be three doses,” he said, explaining that waiting a few months in between doses allows the immune system to develop a full and mature response, which is then further helped by a boost.
If the FDA and the CDC’s Advisory Committee on Immunization Practices (ACIP) endorse a booster dose, the federal government will promote it, White House Covid-19 response coordinator Jeff Zients said.
“Once the FDA and ACIP make their recommendations on boosters, that same intensity of operations and coordination and partnership will be applied to the booster campaign,” Zients said.
Johnson & Johnson is also studying the possibility of adding a second dose as a booster to its one-shot vaccine.
Survey: More than 80% of Americans 16 and older have immunity
The team, led by the CDC’s Dr. Jefferson Jones, set out to determine how close the US might be to some kind of herd immunity — although they do not claim to have any kind of handle on that yet.
They worked with 17 blood collection organizations working in all 50 states plus Washington, DC, and Puerto Rico to test blood covering 74% of the population. In the end, they tested about 1.4 million samples.
In July 2020, before any vaccine was available, 3.5% of samples carried antibodies to SARS-CoV-2, the virus that causes Covid-19. That rose to 11.5% by December, they reported in the medical journal JAMA. By May, 83.3% of samples had antibodies to the virus, most of them from vaccination.
And while in July 2020, blood surveillance indicated the US was only counting one infection out of every three true infections, that fell to one in two a year later.
“Several large studies have shown that among individuals who are seropositive from prior SARS-CoV-2 infection, COVID-19 incidence is reduced by 80% to 95%, similar to vaccine efficacy estimates,” they noted.
“The study will continue until at least December 2021, and results will be made available on the CDC’s website,” they wrote.
More than 500,000 children tested positive for Covid-19 in 3 weeks
“The virus is raging in all these children who are unvaccinated, which is why in schools mask mandates are so important,” CNN medical analyst Dr. Jonathan Reiner told Jake Tapper last week, pointing out that inoculation rates are also low among adolescents who are eligible. “They have no other protection. They’re literally sitting ducks.”
“We all need to remain vigilant to protect each other – and that means coming in to get your shot and booster shot, wearing masks in indoor spaces, and exercising basic safety measures that we are all familiar with by now,” Hochul said.
For teens ages 12 and up attending classes, it remains imperative for them to receive vaccinations to help curb the spread of Covid-19, officials say. And vaccine mandates, while unpopular to some, may be a necessary step.
“This is not something new. We have mandates in many places in schools, particularly public schools, that if in fact you want a child to come in — we’ve done this for decades and decades requiring (vaccines for) polio, measles, mumps, rubella, hepatitis,” Fauci said. “So this would not be something new, requiring vaccinations for children to come to school.”
Officials expect additional vaccine data soon
If authorized, the CDC would move quickly to recommend the use of Covid-19 vaccines in younger children, agency director Dr. Rochelle Walensky said.
“Everybody is looking at this with urgency. Everyone recognizes how important it is for those children to have access to vaccines,” Walensky said during a National Parent Teacher Association town hall Wednesday.
The US Food and Drug Administration (FDA) must approve or authorize the vaccines in younger children first, Walensky noted. And the vaccine makers must make the case to the FDA with clinical trial data.
“My understanding of the timeline is pretty consistent with what is being said — the middle of fall is my understanding, early fall is when we will anticipate seeing the data — and then it will lie with the hands of the FDA. And I’m hopeful for the end of the year,” she said.
Pfizer/BioNTech’s vaccine has been fully approved by the FDA for Americans 16 and older, and emergency use authorization has been granted for those 12 and up. The Moderna and Johnson & Johnson vaccines are under emergency use authorization only for adults 18 and older.
Clinical trials of vaccines for children under the age of 12 are ongoing.
Fauci said Wednesday that the FDA should have the data to consider authorizing a Covid-19 vaccine for children under 12 by the end of September.
“We should have enough of the data to examine and make a decision as we get into late September, the beginning of October,” Fauci said. “Then the data will be presented to the FDA, and the FDA will make a determination whether they will grant that under an emergency use authorization or some other mechanism.”
When asked whether a Covid-19 vaccine will be authorized for young children before Thanksgiving, Fauci said he hopes so, but does not want to get ahead of the FDA.
Correction: An earlier version of this story overstated the percentage of Americans who have some immunity to coronavirus. More than 80% of Americans 16 and older have some immunity.
