American coronavirus: Vaccines protect less against Delta infection but still reduce risk by two-thirds, CDC study finds

“Although we have seen a reduction in the protection of the Covid-19 vaccine against the Delta variant, it is still a two-thirds reduction in risk,” senior author Ashley Fowlkes, epidemiologist, told CNN on Tuesday. for CDC Covid-19 Emergency Response. .

The study’s reliance on regular weekly testing helps capture a more complete picture of Covid-19 infections in a group, as people with mild or no symptoms may be less likely to get tested overall. In official vaccine trials, efficacy has been calculated against symptomatic Covid-19 – not all infections.

Still, the authors warn that there is some uncertainty in these estimates, in part because they found relatively few infections in the first place. In the months when Delta was predominant, researchers found 19 infections in 488 unvaccinated people and 24 infections in 2,352 fully vaccinated people.

Although the decrease in immunity may also contribute to some degree of reduced protection, the present study could not show this significantly. Separate research suggests that even if a fully vaccinated person is infected with the virus, they are less likely to spread it. About 51.5% of the population is fully vaccinated, according to data from the CDC.

The study authors plan for future analyzes comparing different Covid-19 vaccines as well as the types of symptoms experienced by vaccinated and unvaccinated people who become infected.

“It’s still a very potent vaccine,” Fowlkes added, especially when it comes to more serious results. “But we are also considering continuing to use masks for a bit longer.”

Separately, a new Los Angeles County study reaffirms that fully vaccinated people are much less likely than unvaccinated people to be hospitalized, admitted to an intensive care unit, to need mechanical ventilation, or to need extra care. die from Covid-19.

“On July 25, the infection and hospitalization rates among unvaccinated people were 4.9 times and 29.2 times those of fully vaccinated people, respectively,” wrote researchers from the County Public Health Department. Los Angeles in the study, which was published Tuesday by the CDC.

Fauci predicts Covid could be ‘under control’ by spring

Despite these studies of the benefits of vaccination, tens of millions of people have hesitated to get vaccinated. Because of this, hospitals in many states with lower vaccination rates are overwhelmed by an increase in patient numbers, students returning to class to have to self-isolate due to exposure and cases in children. are increasing.

Mississippi reported 111 new Covid-19-related deaths on Tuesday, a one-day record, state epidemiologist Dr Paul Byers said on Tuesday. 87% of new deaths are among the unvaccinated and more than 50% are over 65, he said. Gov. Tate Reeves said on Tuesday more than 1,000 health workers had arrived to help fill hospital staff shortages.

“Putting boots on the pitch so quickly is a step in the right direction,” he said.

Florida also reported a record average of around 212 Covid-19 deaths every day last week, according to data from Johns Hopkins University.

Dr Anthony Fauci urged the public to get vaccinated and said if the “overwhelming majority” of the population does, the United States could have the pandemic “under control” by spring 2022.

“We hope we’ll be there… but there’s no guarantee because it’s up to us,” CNN’s Anderson Cooper told CNN Fauci, director of the National Institute of Allergy and Infectious Diseases and medical adviser on Monday. head of the president.

As hospitalization rates skyrocket, FDA grants full approval for Pfizer / BioNTech Covid-19 vaccine

Health experts do not yet know what proportion of the population needs to be vaccinated to achieve a level of protection that could support a return to normalcy, such as going safely to restaurants and theaters, Fauci said. The best way forward, therefore, is to vaccinate as many people as possible, he said.

Still, Fauci’s spring 2022 timeline is politically intimidating for President Joe Biden, who has already declared a partial victory over the virus on July 4. In addition, CNN chief medical correspondent Dr Sanjay Gupta questioned the definition of what it means to “control” a virus that appears to be there for the long haul.

“This is one of those situations where I think defining what it means to be in control of the pandemic is really important,” Gupta said Tuesday.

“If we have more people vaccinated, it’s likely that we’ll separate hospitalizations from cases, and maybe that will be a definition of control. (If) people don’t get so sick anymore, end up in hospital, the virus is slowly starting to have no places to circulate, that will be a definition of control. I think we’ll see waves of it for a while, “he added.

FDA approval opens door to warrants

On Monday, the United States Food and Drug Administration fully approved the Pfizer / BioNTech Covid-19 vaccine for people 16 years of age and older, a move that health officials say will convince hesitant Americans to get vaccinated .

“I think the approval announced yesterday by the FDA for the Pfizer vaccine is an important step in our vaccination efforts and it reaffirms what we have been seeing for months,” US surgeon general Vivek Murthy told CNN. “That is, vaccines are very effective, they have a very strong safety profile, and they are what we need to get through this pandemic.”

There are still nearly 80 million people eligible for vaccination who have not yet done so.

“I think there will be a modest increase, but look, we have a long way to go to fill this gap,” said Dr Peter Hotez, vaccinologist and dean of the National School of Tropical Medicine at Baylor College of Medicine. “I think having full approval will certainly convince some of this, but this is just one of the twelve false talking points put forward by the disinformation campaign. And, I think a number of people will just go back to one of the others. “

Full approval of the Covid-19 vaccine will not only build confidence.  This will likely lead to new business demands, says surgeon general

FDA approval also opens the door for businesses and government agencies to mandate vaccinations, and some have already started doing so.

On Monday, New York City Mayor Bill de Blasio mandated the vaccine for all Department of Education employees, including teachers. In addition, then New York Governor Andrew Cuomo issued a statement on Monday, before stepping down, calling on all New York State employers to demand vaccination against Covid-19. The state already requires that all eligible government and health care employees be immunized.

Now that the FDA has granted full approval for the Pfizer vaccine, the next goal is to authorize a Covid vaccine for children aged 5 to 11. This could happen by the end of the year as part of an updated emergency use authorization, officials said.

If and when that authorization comes, at least 28 million more children – representing about 9% of the U.S. population – would become eligible to receive the vaccine, according to a CNN analysis of federal data.

If immunization trends among the 5 to 11 age group are consistent with those in the 12 to 15 age group, approximately 7 million children aged 5 to 11 could receive their first dose of vaccine within one month and over 9 million within two months. . This would increase the overall vaccination rate in the United States by about 2 percentage points in one month and 3 percentage points in two months.

About 54% of parents of children under 12 said they “agree” or “strongly agree” that they would vaccinate their children against Covid-19 “when a vaccine is licensed and available for their age, ”according to a Rockefeller Foundation survey conducted by the RAND Corporation.

Florida Covid-19 deaths hit record high as new cases continue to rise

Florida reported more Covid-19 deaths last week than at any time during the pandemic, according to data from Johns Hopkins University, and hospitalizations are also higher than ever.

The state broke its January record for new daily cases about two weeks ago, and that number has continued to rise to the current average of around 21,534 per day.

Just weeks after the start of the school year for many districts in Florida, more than 14,000 cases of Covid-19 – among 11,851 students and 2,610 employees – have been reported in the 15 largest school districts in the Status since the start of the school year, according to a CNN analysis.

Several school districts are defying the governor’s order, requiring masks from all students with no ability for parents to decide to step down.

The St. Johns School District, which includes Saint Augustine, on Tuesday announced a mask warrant for all employees and visitors to its schools, but not its students, for the next 30 days, as cases of Covid-19 are multiplying in the region.
