‘Not Out of the Woods’: C.D.C. Points Warning to the Unvaccinated

WASHINGTON – The director of the Centers for Disease Control and Prevention warned Thursday that the United States was “not yet out of the woods” with the pandemic and was again at a “key point” when the highly contagious Delta variant tore through unvaccinated Municipalities.

Just weeks after President Biden threw a party on July 4th on the South Lawn of the White House to declare independence from the virus, the director named Dr. Rochelle P. Walensky the now dominant variant “one of the most contagious respiratory viruses”. Known to scientists.

The renewed urgency within the administration was directed at tens of millions of people who have not yet been vaccinated and are therefore most likely to be infected and become ill. Her grim message came at a time of mounting fear and confusion, especially among parents of young children who are still unsuitable for the injection. And it underscored how quickly the recent surge in the pandemic had unsettled Americans, who had begun to believe the worst was over and prompted politicians and public health officials to recalibrate their responses.

“This is like the moment in horror movies when you think the horror is over and the credits are about to begin,” said Rep. Jamie Raskin, Democrat of Maryland. “And everything starts all over again.”

The decision by millions to reject the vaccine had the consequences health officials had predicted: the number of new cases in the country has increased nearly 250 percent since the beginning of the month, with an average of more than 41,000 infections diagnosed each day Week – versus 12,000.

The disease caused by the virus kills about 250 people each day – far fewer than during the peak period last year, but still 42 percent more than two weeks ago. More than 97 percent of hospital patients are unvaccinated, said Dr. Walensky last week.

The public health crisis is particularly acute in parts of the country where vaccination rates are lowest. In Louisiana, Mississippi, Alabama, and Florida, the number of new cases every day has increased more than 200 percent in the past two weeks, leading almost entirely to new hospital admissions and deaths among the unvaccinated. Intensive care units are being filled or replenished in southern Missouri and northern Arkansas.

The turnaround is forcing both political parties in Washington to grapple – hitherto hesitantly and hesitantly – with questions about what tone to use, what guidance to give, and what changes to make to meet the latest generation of the worst public Health crisis in a century.

The White House on Thursday announced new grants to local health departments for vaccines and stepped up testing in rural communities, despite administrative officials saying they would “make further progress in our fight against the virus” and insisted it was not necessary to do their basic Rethink measures strategy. Although reports of breakthrough infections in vaccinated people are increasing, they remain relatively rare and those that cause serious illness, hospitalization, or death are particularly rare.

But the rise in infections and hospitalizations in some parts of the country, even if mostly limited to people who have chosen not to vaccinate, has presented Mr Biden with an evolving challenge that threatens economic recovery and his own political standing could.

The stock market is shaky. His administration is under renewed pressure to reintroduce mask mandates, as Los Angeles County did this week. And the president’s top aides are on the defensive in their strategy to keep the pandemic in check again.

“It’s frustrating,” Mr. Biden admitted Wednesday night during a town hall event on CNN.

The rise of the variant could also change the equation for some Republicans who see many of their own constituents hospitalized – or worse. Louisiana Rep. Steve Scalise, the No. 2 Republican in the House of Representatives, received his first shot on Sunday, noting a “further spike” in the pandemic. Fox News host Sean Hannity said on his show, “I believe in the science of vaccination.”

On Capitol Hill, House Republican leaders and doctors were reluctant to signal their support for vaccinations Thursday, even though that support was mixed.

“If you are at risk you should get this vaccine,” said Maryland doctor Andy Harris, adding, “We urge all Americans to speak to their doctors about the risks of Covid and to speak to their doctors about the benefits.” get vaccinated and then make a decision. “

Republican Rep. Greg Murphy, North Carolina, said, “This vaccine is a medicine and, like any other medicine, there are side effects and it is a personal choice.”

Their press conference was promoted as an attempt to “discuss the need for vaccination for individuals”. But it was dominated by efforts to spread an unproven theory that the Chinese released a virulent, man-made virus in the world and allegations that the Democrats were covering it up.

The vaccines work to protect those who have been injected from serious danger, but charts tracking the pandemic, which has been declining for months – heralded by Mr Biden as evidence his approach worked – are going up sharply.

The rapid momentum of the new variant makes people wonder whether they have to withdraw from restaurants, cinemas, bars, sporting events and their offices again. What seemed like clear – and mostly positive – decisions just a few days ago now seems muddy.

White House officials on Thursday turned down questions about whether vaccinated people should return to wearing masks indoors, as Los Angeles County health officials ordered days ago. Jeffrey D. Zients, the White House’s coronavirus coordinator, just said that the CDC’s current guidelines don’t require it.

“It is up to each and every American to make their own contribution,” he said. “We know that every vaccination route is different. We are ready to have more Americans vaccinated anytime, anywhere. “

Amid the concern, one thing is clear: the variant has once again turned hopes of an end to the pandemic on its head and sparked a new fear on the horizon – that a highly anticipated return to work and school could be disrupted after much of the country’s nearly 18 Months of seclusion from home.

“I’m concerned about the fall,” said Rep. Lauren Underwood, an Illinois Democrat and registered nurse. “August will be tough. It’s going to be tough back to school. We will see more sickness and more death. “

Andy Slavitt, a public health expert who recently left the Biden White House’s coronavirus response team, said the government would not consider mandating vaccinations for the military or federal workers until the Food and Drug Administration clears the coronavirus – Vaccines that are now available have been given permanent authorization under emergency use authorization.

However, the final approval of the Pfizer vaccine will take place “within weeks to a few months”. Once that happens, he said, “it should all be on the table and I can tell you that is the attitude in the White House.”

Public school systems could also require vaccinations at this point, just as they would require vaccinations against polio, measles, mumps, and rubella – with a few exceptions for religious or health reasons. That would quickly drive up vaccination rates.

Aside from mandates, there are few obvious policy changes as Congress has already inundated health officials with funding for vaccination campaigns and making vaccines widely available. Ami Bera, a Democrat from California, who is a doctor, suggested that the Biden government launch a public advertising campaign modeled on smoking cessation campaigns in which a dying man once smoked through his windpipe.

“Let’s do an ad with a 20 year old man who says, ‘I didn’t take it seriously. I got it and killed my grandmother, ”he said.

Republicans have emphasized their refusal to go backwards.

“You don’t have to shut things down,” said Kansas Senator Roger Marshall, a doctor. “Look, as far as I know, no child under the age of 18 has died of Covid unless they also had a serious illness.”

The death toll among American children is extremely small – 346 on July 15 – but some of them most likely did not have any underlying health conditions.

Even the Republicans have so far resisted sounding the alarm in the conservative population. The Kaiser Family Foundation reported in late June that 86 percent of Democrats had at least one shot, compared to 52 percent of Republicans.

Policy makers are feeling paralyzed, in large part because once Americans resume life without masks and other restrictions, it will be difficult to return. Vaccination and masking requirements would almost certainly trigger a violent backlash, but could also save lives.

“We all have this psychology, well, it’s over, but intellectually we know it’s not over yet,” said Maryland Rep. Steny H. Hoyer, the Majority Leader. He asked, “How do we get a society that had an enormous feeling of being locked in a mask, then being free again, to go back?”

Delta variant is without doubt one of the most infectious respiratory illnesses identified, CDC director says

Rochelle Walensky, director of the CDC

The Delta-Covid variant is one of the most contagious respiratory diseases scientists have ever seen, the director of the Centers for Disease Control and Prevention said Thursday.

The variant is highly contagious, mainly because people infected with the Delta strain can carry up to 1,000 times more virus in their nasal passages than those infected with the original strain, according to new data.

“The Delta variant is more aggressive and much more transmissible than previously circulating strains,” said CDC Director Dr. Rochelle Walensky reporters at a briefing Thursday. “It’s one of the most contagious respiratory viruses we know and that I’ve seen in my 20-year career.”

The Delta variant has spread rapidly in the US and currently accounts for more than 83% of the cases sequenced in the US, up from 50% in the week of July 3rd.

The seven-day average of new cases has increased by around 53% compared to the previous week and is currently 37,674 new cases per day. Hospital admissions are up 32% to about 3,500 per day from last week, and deaths are up 19% to about 240 per day over the same period.

“This virus has no incentive to wear off and it remains on the lookout for the next person at risk to infect,” Walensky said.

The virus penetrates US counties with low vaccination rates, while counties with high vaccination rates have lower rates of new infections.

Three states, Florida, Texas and Missouri, with low vaccination rates account for 40% of all new cases nationwide, White House Covid Tsar Jeff Zients said. Florida alone accounted for one in five of all new cases in the United States for the second straight week.

In hospitals across the country, 97% of people admitted with Covid symptoms are unvaccinated, and 99.5% of all Covid deaths are also unvaccinated.

For the past week, the five states with the highest case numbers had higher rates of people getting re-vaccinated compared to the national average.

“We are at another pivotal moment in this pandemic as cases are picking up again and some hospitals are reaching capacity in some areas. We need to come together as a nation,” Walensky said.

CDC Says Delta Variant Makes Up an Estimated 83 % of US Circumstances

The highly infectious Delta variant now accounts for an estimated 83 percent of new coronavirus cases in the United States — a “dramatic increase” from early July, when it crossed the 50 percent threshold to become the dominant variant in this country, the director of the Centers for Disease Control and Prevention said Tuesday.

In some regions, the percentage is even higher — particularly where vaccination rates are low, Dr. Rochelle Walensky, the C.D.C. director, said during a Senate health committee hearing. Two-dose vaccines have been shown to be effective against the Delta variant but questions have been raised about Johnson & Johnson’s single-dose regimen against Delta. While almost 60 percent of U.S. adults are fully vaccinated, less than half of the total U.S. population is.

She said the C.D.C. would update its website later Tuesday to reflect the new estimate of Delta cases, which the agency derives from gene sequencing of new coronavirus cases.

The new figure comes as new cases have been rising across the United States, though cases, hospitalizations and deaths remain a fraction of their peaks. Still, public health experts are watching the increases with deep concern and Dr. Walensky warned last week that “this is becoming a pandemic of the unvaccinated.” The seven-day average now shows nearly 38,000 new daily cases, up from about 11,000 a day not long ago, according to a New York Times database.

Tuesday’s hearing was contentious at times. Senator Mitt Romney, Republican of Utah, pressed Dr. Janet Woodcock, the acting commissioner of the Food and Drug Administration, on when the F.D.A. would authorize booster shots — and was not happy when she could not provide a specific answer. Federal health officials have said booster shots are not necessary now and have pressed Pfizer for more evidence.

Other Republicans clashed with witnesses over matters including mask mandates, booster shots for Covid-19 vaccines and “gain of function” research designed to identify genetic mutations that could make a virus more powerful.

Senator Rand Paul, Republican of Kentucky, escalated his long-running attacks on Dr. Anthony S. Fauci, President Biden’s top medical adviser for the coronavirus pandemic, and accused Dr. Fauci of committing a crime by lying to Congress in May when he told senators that the National Institutes of Health did not fund “gain of function” research at a laboratory in Wuhan, China, the epicenter of the pandemic’s early days.

Dr. Fauci, in turn, accused the senator of falsely implying that the N.I.H. is somehow responsible for hundreds of thousands of deaths from the pandemic — an extraordinary exchange for the Senate, where witnesses almost always defer to lawmakers.

“I have never lied before Congress and I do not retract that statement,” Dr. Fauci declared, adding, “Senator Paul, you do not know what you are talking about, quite frankly, and I want to say that officially.”

C.D.C. Director Warns of a ‘Pandemic of the Unvaccinated’

As the highly contagious Delta variant of the coronavirus fuel outbreaks in the United States, the director of the Centers for Disease Control and Prevention warned on Friday that “this is going to be a pandemic of the unvaccinated”.

Cases, hospitalizations, and deaths remain well below last winter’s peak, and vaccines are effective against Delta, but CDC director Dr. Rochelle P. Walensky, urged people to get fully vaccinated for robust protection, pleading, “Do it for yourself, your family, and for your community. And please do it to protect your young children who cannot be vaccinated at the moment. “

The number of new virus cases is likely to increase in the coming weeks, and those cases are likely to be concentrated in low-vaccination areas, officials said at a White House briefing on the pandemic.

“Our greatest concern is that we will continue to see preventable cases, hospital admissions and, unfortunately, deaths among the unvaccinated,” said Dr. Walensky. According to a New York Times database, the nation exceeded 34 million cumulative cases as of Friday.

Delta now accounts for more than half of the new infections across the country, and the number of cases has increased in all states. Around 28,000 new cases are reported every day, up from just 11,000 per day less than a month ago.

So far, data suggests that many of the vaccines – including Pfizer-BioNTech, Moderna, and Johnson & Johnson vaccinations – offer good protection against Delta, especially against its worst outcomes, including hospitalization and death. (Receiving a single dose of two-shot therapy, however, offers poor protection against the variant.) Nearly 60 percent of US adults were fully vaccinated, but fewer than 50 percent of Americans were vaccinated; only people aged 12 and over are eligible to participate.

“We have come a long way in our fight against this virus,” said Jeffrey D. Zients, the government’s Covid-19 response coordinator, at the briefing.

The rate of vaccination has slowed considerably since the spring and the rate of vaccination remains very inconsistent. Delta is already skyrocketing case numbers in undervaccinated areas, including parts of Missouri, Arkansas and Louisiana.

The World Health Organization recently reiterated its recommendation that vaccinated people should continue to wear masks, also because of the global spread of Delta.

Updated

July 16, 2021, 9:50 p.m. ET

However, the CDC has stood by its mask policy, with Dr. Walensky pointed to WHO’s global jurisdiction and the fact that wealthy nations took so many of the recordings available. She added that local officials in the United States can opt for stricter measures to protect the unvaccinated.

On Thursday, the Los Angeles District said that as of this weekend, indoor mask requirements will be reintroduced for everyone, regardless of vaccination status. On Friday, Dr. Walensky pointed out the heterogeneity of the country and said: “These decisions have to be made at the local level.”

“If you have areas with low vaccination and high case numbers, I would say local politicians are considering whether masking would be helpful for their community at this point,” she added.

In New York City, Mayor Bill de Blasio said Friday there are currently no plans to reinstate a mask mandate for everyone across the city, nor did he consider the move necessary. The city recently reported a streak of more than 400 cases per day, up from an average of about 200 per day a few weeks ago. “We have to see it like a hawk,” he said on a radio broadcast, referring to the Delta variant.

Health officials are focusing on hospital stays that have remained low over the past few weeks. According to the city, about 53 percent of city residents are fully vaccinated. Should hospital stays increase, the city will adapt.

“We currently have no plan to change course,” he said. “When we see something that we need to change, we say it right away and call people to arms.”

After narrowly missing a self-imposed target of at least partially vaccinating 70 percent of adults by July 4, the Biden government is trying again to reach out to those who have still not received their vaccinations. Officials also recently announced the creation of surge response teams to help hard-hit states manage delta-driven outbreaks. Missouri and Nevada have already asked for help.

The C.D.C. Points New College Steerage, With Emphasis on Full Reopening

In another shift, the C.D.C. made clear that masks could be optional for vaccinated people, in line with its recommendations for the general public.

Still, the agency said that schools may opt to require universal masking if local cases were rising, for example, or if a school could not determine how many of its students and staff members were vaccinated. And it urged schools to “be supportive of people who are fully vaccinated, but choose to continue to wear a mask.” In general, students and staff members did not need to be masked when outdoors, the agency said.

The C.D.C. also strongly urged schools to promote vaccination, which the guidance called “one of the most critical strategies to help schools safely resume full operations.” Studies suggest that vaccines remain effective against the Delta variant.

The country’s two major teachers’ unions, which have close relationships with the Biden administration, praised the guidance. Randi Weingarten, the president of the American Federation of Teachers, whose members in some cases fought the reopening of schools this past school year, said the recommendations are “grounded in both science and common sense.”

Still, both school and public health officials predicted challenges ahead.

Ms. Weingarten said the mask guidance posed a particular test, since classes with students 12 and older would most likely include a mix of vaccinated and unvaccinated students. Many officials in areas with low vaccination rates have already said they will not require masks in schools — and at least eight states have already banned such requirements.

Some parents who have advocated school reopening greeted the new guidelines with relief. Meredith Dodson, whose son is entering kindergarten this fall in San Francisco, organized a group of parents who spent the last school year fighting for the city to open its schools. The city finally allowed elementary school students to return in mid-April, but most middle and high school students were not able to do so at all.

“This is a huge step in the right direction,” Ms. Dodson said.

Many schools have already largely or entirely returned to in-person learning. By mid-spring, the vast majority of districts had allowed at least younger students to return to classrooms, although many, especially on the West Coast, only allowed them to attend part-time. Many families — especially Asian American, Black and Hispanic families — chose to keep their children learning remotely.

Educators’ Unions Reward C.D.C. Faculties Steerage However Acknowledge Challenges

The two largest U.S. unions representing educators on Friday approved the new federal guidelines calling for schools to be fully reopened, while allowing children under 12 who are not eligible for vaccination to go ahead face further challenges.

The new recommendations, issued on Friday by the Centers for Disease Control and Prevention, come after students, teachers and parents experienced a disruptive school year marked by changing guides, school closings and hastily implemented distance learning plans to contain the coronavirus .

Education has been a focus since the pandemic broke out when many teachers and families feared in-person tuition. But distance learning has proven to be an inadequate substitute for many parents and students, and virtually all major counties are planning to reopen full-time schools this fall – though they have yet to convince some reluctant parents to return their children.

Education Minister Miguel Cardona said in a statement Friday that “our top priority is to ensure that our nation’s students can safely study in person in their schools and classrooms.”

The new CDC guidelines will help educators achieve this goal, union leaders said.

Becky Pringle, president of the National Education Alliance, the country’s largest teachers’ union, said in a statement the guidelines are an “important roadmap to reducing the risk of Covid-19 in schools.”

Randi Weingarten, president of the American Federation of Teachers, who has already pushed for schools to fully reopen this fall, said in her own statement that “The guidelines affirm two truths: that students learn better in the classroom and that vaccines are ours the best bet is to stop the spread of this virus. “

The new recommendations call for vaccinating as many people as possible, wearing masks for the unvaccinated in schools, a meter spacing between students and the superposition of various preventive tactics.

“For educators across the country, this guide sets a lower limit, not an upper limit; it builds on the evidence we have about the transmission of Covid and reminds us that we need to remain committed to other containment strategies, “said Ms. Weingarten, adding that” we address the growing concern about the Delta variant as well The evolving science around Covid share transmission among young people making it mandatory for school districts to be committed to both vaccinations and these safety protocols. “

Studies suggest that vaccines against the Delta variant remain effective.

The new guidelines also suggest that districts base their approaches on local conditions rather than general regulations, an approach that Ms. Pringle welcomed.

“It is important that we listen to the special needs of all of our schools and the communities they serve,” said Ms. Pringle. “We as a country have a responsibility to cope with the disproportionate burden that colored communities suffered during this pandemic, which has contributed to families reluctance or reluctance to allow their children to return to face-to-face education.”

Schools proved far safer than many had thought during the pandemic, and in general, serious illness and child deaths were rare. Young children are also less likely to transmit the virus to others than teenagers and adults.

Meisha Porter, the chancellor of New York Schools, the largest school system in the country, reiterated the plan to bring students back to full-time face-to-face classes in September.

“Science shows that our rigorous, multi-faceted approach has made our schools the safest places to be, and we are reviewing CDC guidelines with our health professionals,” Porter said in a statement.

However, no vaccines have been federally approved for children under the age of 12, and children have made up a larger proportion of cases over the course of the pandemic, although there are far fewer cases overall than during the winter peak.

Scientists are concerned about an inflammatory syndrome that can appear in children weeks after contracting the virus, even those who were asymptomatic with the infection, and some children experience persistent symptoms often known as long covid.

The highly communicable delta variant is spreading rapidly in areas with low vaccination rates – the CDC estimates that it is now the predominant variant in the United States.

Expert opinion on the new guidelines was mixed.

Dr. Benjamin Linas, an infectious disease specialist at Boston University, called the proposals “scientifically sound and just right”.

“For the first time, I really think they hit it in the nose,” he said.

Emily Oster, Brown University economist and parenting book author who entered the controversial school reopening debate last year and used data to argue that children should return to school in person, said they were generally comfortable with the framework of the Agency was satisfied, which it said gave the districts a roadmap for reopening without being overly prescriptive.

Despite pushing for even more relaxed leadership – for example, the complete abolition of the three-foot rule – she said the new recommendations give districts important flexibility.

“This is in some ways the most positive I have about your advice,” said Dr. Easter.

But Jennifer B. Nuzzo, an epidemiologist at Johns Hopkins University, feared the debate among local officials about the best security protocols could prove “crippling”.

Speaking at a press conference on Friday, White House press secretary Jen Psaki said that the decision on what action to take has “always been the responsibility of the local school district.”

The coverage is from Sheryl Gay Stolberg, Emily Anthes and Sarah Mervosh.

CDC says totally vaccinated academics and college students needn’t put on masks indoors in up to date steering

The Centers for Disease Control and Prevention updated its public health guidance for schools Friday, saying fully vaccinated teachers and students don’t need to wear masks inside school buildings.

The CDC’s new guidance comes about two months after federal health officials permitted the use of the Pfizer-BioNTech Covid vaccine for kids ages 12 to 15, allowing middle and high school students to get the shots ahead of the fall school semester.

Teachers and students who are not vaccinated should still continue to wear masks indoors, the U.S. agency said, adding the practice is especially important when inside and in crowded settings, when social distancing cannot be maintained.

The agency also said it still recommends that students remain at least 3 feet apart in classrooms, combined with indoor mask wearing by people who are not fully vaccinated, to reduce the risk of transmission of the virus.

“When it is not possible to maintain a physical distance of at least 3 feet, such as when schools cannot fully re-open while maintaining these distances, it is especially important to layer multiple other prevention strategies, such as indoor masking,” the CDC wrote in its guidance.

The CDC’s recommendation will likely have no impact on students under 12, who are currently ineligible to get a Covid vaccine in the U.S.

The updated guidance comes as several states across the U.S. have largely done away with their mask requirements, social distancing and other pandemic-related restrictions because the Covid vaccines have helped drive down the number of new infections and deaths.

In mid-May, the CDC said fully vaccinated people didn’t need to wear masks in most settings, whether indoors or outdoors. They are still expected to wear masks on public transportation, the agency said, such as on airplanes, buses and trains. The federal government’s mask mandate on public transportation is scheduled to expire on Sept. 13 unless the CDC extends it once again.

The guidance may be controversial as scientists and other health experts say indoor mask mandates many make a return this fall, particularly in low vaccinated states, as the highly transmissible delta variant spreads across the U.S.

Already the dominant variant in the U.S., delta will hit the states with the lowest vaccination rates the hardest — unless those states and businesses reintroduce mask rules, capacity limits and other public health measures that they’ve largely rolled back in recent months, experts say.

Delta Is Dominant Variant within the U.S., C.D.C. Estimates

However, vaccination protection remains very inconsistent in both the United States and around the world, and public health experts say Delta poses a serious threat to unvaccinated populations. On Tuesday, President Biden again urged Americans to get their shots, citing concerns about Delta.

“It works. It’s free. And it’s never been easier and it’s never been more important,” he said. “Do it now – for yourself and the people you care about, for your neighborhood, for yours Country. It sounds cheesy, but it’s a patriotic thing. “

Health experts say the Biden government may need to take more aggressive action to promote vaccination, including asking employers and schools to adopt vaccine mandates. As of Tuesday, providers were administering an average of about 0.87 million doses per day, a 74 percent decrease from the April 13 peak of 3.38 million, according to federal data.

As for the virus itself, the country has averaged fewer than 15,000 new cases a day for nearly a month, the lowest level since testing became widely available, and a fraction of what was reported in January when the nation routinely exceeded 200,000 Cases identified in a day. In the past few days, however, the average number of new cases nationwide has started a slight upward trend, largely due to localized outbreaks in places with low vaccination rates, including parts of Missouri, Arkansas, and Nevada.

As the Delta variant spreads around the world, the World Health Organization recently reiterated longstanding guidance that everyone, vaccinated or not, wear masks as a precautionary measure, but the CDC hasn’t changed its recommendation that fully vaccinated people wear masks in most situations can skip. US health officials have suggested that the WHO’s blanket proposal was influenced by its global reach, as many countries had far less access to vaccines than the United States.

CDC leaving it as much as states to set tips for masks, director says

Rochelle Walensky, director of the U.S. Centers for Disease Control and Prevention (CDC), takes off a protective mask during a Senate Appropriations Subcommittee hearing in Washington, D.C., U.S., on Wednesday, May 19, 2021.

CDC Director Dr. Rochelle Walensky said Wednesday the U.S. agency is leaving it up to states and local health officials to set guidelines around mask-wearing even after the World Health Organization urged fully vaccinated people to continue the practice.

The Centers for Disease Control and Prevention has “always said that local policymakers need to make policies for their local environment,” Walensky said during an interview on the NBC program “TODAY.” She added that the agency’s guidelines broadly recommend that vaccinated people don’t need to wear masks.

“There are areas of this country where about a third of people are vaccinated, they have low vaccination rates,” Walensky said. “There are areas where they have more disease in the context of people not being vaccinated. So, in those areas, we’ve always said please look, make suggestions.”

She added, “If you are vaccinated, you are safe from the variants that are circulating here in the United States.”

The CDC director’s comments come days after WHO officials urged fully vaccinated people to continue to wear masks, social distance and practice other pandemic safety measures as the highly contagious delta variant spreads rapidly across the globe.

Delta, now in at least 92 countries, including the United States, is expected to become the dominant variant of the disease worldwide, according to the WHO. In the U.S., the prevalence of the strain is doubling about every two weeks.

WHO officials said Friday they are asking fully vaccinated people to continue to “play it safe” because a large portion of the world remains unvaccinated and highly contagious variants, like delta, are spreading in many countries and spurring outbreaks.

“People cannot feel safe just because they had the two doses. They still need to protect themselves,” Dr. Mariangela Simao, WHO assistant director-general for access to medicines and health products, said during a news briefing.

The WHO’s comments were a departure from the CDC, which has said fully vaccinated Americans can go maskless in most settings, and sparked widespread confusion.

Walensky said Wednesday that the WHO makes recommendations for a global population, adding many regions of the world remain unvaccinated.

“When the WHO makes those recommendations, they do so in that context,” she said.

Still, while many states have lifted most of their mask restrictions, places like Mississippi are recommending that residents continue to wear masks indoors even if they are fully vaccinated.

Delta is the dominant variant in Mississippi right now and only 31% of the state’s eligible population is vaccinated, state health officials said on a call late Tuesday. About 96% of new Covid cases are unvaccinated people, they added.

CDC says greater than 4,100 individuals have been hospitalized or died after vaccination

More than 4,100 people have been hospitalized or died with Covid-19 in the U.S. even though they’ve been fully vaccinated, according to new data from the Centers for Disease Control and Prevention.

So far, at least 750 fully vaccinated people have died after contracting Covid, but the CDC noted that 142 of those fatalities were asymptomatic or unrelated to Covid-19, according to data as of Monday that was released Friday.

The CDC received 3,907 reports of people who have been hospitalized with breakthrough Covid infections, despite being fully vaccinated. Of those, more than 1,000 of those patients were asymptomatic or their hospitalizations weren’t related to Covid-19, the CDC said.

“To be expected,” Dr. Paul Offit, a top advisor to the Food and Drug Administration on children’s vaccines told CNBC. “The vaccines aren’t 100% effective, even against severe disease. Very small percentage of the 600,000 deaths.”

Breakthrough cases are Covid-19 infections that bypass vaccine protection. They are very rare and many are asymptomatic. The vaccines are highly effective but don’t block every infection. Pfizer and Moderna’s phase three clinical studies found that their two-dose regimens were 95% and 94% effective at blocking Covid-19, respectively, while Johnson & Johnson’s one-shot vaccine was found to be 66% effective in its studies. All three, however, have been found to be extremely effective in preventing people from getting severely sick from Covid.

The CDC doesn’t count every breakthrough case. It stopped counting all breakthrough cases May 1 and now only tallies those that lead to hospitalization or death, a move the agency was criticized for by health experts.

Most Americans have received at least one shot of the two currently authorized mRNA vaccines. The U.S. has administered 178.3 million shots and fully vaccinated 46% of its population.

“You are just as likely to be killed by a meteorite as die from Covid after a vaccine,” Dr. Peter Chin-Hong, an infectious disease expert at the University of California San Francisco, told CNBC. “In the big scheme of things, the vaccines are tremendously powerful.”

Efficacy rates decrease slightly for variants like alpha and delta, with studies indicating 88% efficacy against the delta strain after two doses of the Pfizer vaccine. It was unclear if any of the reported breakthrough cases were caused by variants.

In Israel and the United Kingdom, concerns about the delta variant are rising after growing reports of breakthrough infections.

Even with 80% of adults vaccinated, Chezy Levy, director-general of Israel’s Health Ministry, said the delta variant is responsible for 70% of new infections in the country. Levy also said that one-third of those new infections were in vaccinated individuals.

In the U.K., Public Health England released a report that found 26 out of 73 deaths caused by the delta variant occurred in fully vaccinated people from June 8 to June 14. Most of the deaths occurred in unvaccinated individuals.

“Determination of whether hospitalizations and deaths are more represented in immunocompromised patients and the type of vaccine received will be important for future guidance,” Chin-Hong said.

On June 7, the CDC received reports of 3,459 breakthrough cases that led to hospitalization or death. On June 18, that number was updated to 3,729, an increase of 270 cases. Today, the number stands at 4,115.

An overwhelming majority, 76%, of the hospitalizations and deaths from breakthrough cases occurred in people over the age of 65.

“We do not have the years and years of data we have for vaccines against other airborne pathogens — and therefore it is really essential that the CDC provides up to date reporting on breakthrough cases,” David Edwards, aerosol scientist and Harvard University professor, told CNBC.

The CDC says its numbers are “likely an undercount” of all Covid infections in vaccinated people because the data relies on passive and voluntary reporting.
