Natural immunity from prior infection granted stronger levels of protection against the Delta variant of COVID-19 than vaccination alone, the Centers for Disease Control and Prevention (CDC) said in a study released Wednesday. Before Delta became dominant, individuals who had natural immunity were experiencing higher case rates than individuals who were only vaccinated, the study found, but after Delta took hold, those with natural immunity caught COVID-19 less frequently than those who were only vaccinated.

The study examined four categories of people — unvaccinated and vaccinated who survived a previous COVID-19 infection, and unvaccinated and vaccinated who had never been infected — in California and New York between May and November 2021. The highest case rates were among those who had neither been vaccinated or previously infected. The most protection against infection and hospitalization was in those who had both been vaccinated and survived an earlier bout with the virus.

The agency cautioned that the data in question only measured results against the Delta variant and that Omicron may present new challenges that alter the calculus of natural immunity versus vaccination. 

Biden administration officials and some public health experts have repeatedly downplayed the effectiveness of natural immunity against COVID-19, but this study is only the latest to indicate that recovery from prior infection can at least rival, if not surpass, that offered from vaccination alone. Most research has shown that for maximum protection against reinfection or severe illness, those who were previously infected should still get vaccinated.

Many legacy media outlets covered the study by minimizing the finding that natural immunity outperformed vaccines and emphasizing that a combination of both provided the best protection. Headlines from the New York TimesAssociated PressCNN and others claimed that vaccination offers the “best” or “safest” protection according to the study.

In a press call Wednesday, the CDC’s Dr. Benjamin Silk, an epidemiologist that co-authored the study, did not elaborate on the increased protection natural immunity provides and repeated the administration line that every American should get vaccinated.

Stunning new data shows risk of death from Omicron is 91% lower than Delta, CDC-funded study says

The Omicron variant of COVID-19 is far milder than Delta, according to a new study funded by the Centers for Disease Control and Prevention. The eye-opening data revealed that those infected with the Omicron variant are 91% less likely to die than those who are infected than the Delta strain.

The clinical study was conducted by Kaiser Permanente Southern California health care system – which operates 138 medical offices and 13 medical centers, plus has an affiliation with 37 community hospitals in Southern California. The study analyzed 52,297 Omicron cases and 16,982 Delta cases in Southern California between Nov. 30, 2021, and Jan. 1, 2022.

The study found that those infected with the Omicron variant were 53% less likely to have symptomatic hospitalization, had 74% less chance of being administered to the intensive care unit, and had a 91% lower risk of death compared to individuals with the Delta variant. Only one person of the more than 52,000 people with Omicron died, versus 14 deaths in the 16,982 with Delta. In addition, there were zero patients with Omicron who required mechanical ventilation, according to the research.

“Hospital admissions occurred among 235 (0.5%) and 222 (1.3%) of cases with Omicron and Delta variant infections, respectively,” the authors of the study said.

Patients infected with Omicron had a median duration of hospital stay of three fewer days than those with Delta.

“During a period with mixed Delta and Omicron variant circulation, SARS-CoV-2 infections with presumed Omicron variant infection were associated with substantially reduced risk of severe clinical endpoints and shorter durations of hospital stay,” the authors of the study concluded.

The CDC-funded study – which has not yet been peer-reviewed – did not reveal the ages of those who died or their vaccination status. On Wednesday, CDC Director Rochelle Walensky shared the study on Twitter.

Despite the promising news, Walensky tempered the optimism by saying, “While less severe, #Omicron is much more transmissible & we are seeing the unprecedented impact. Over 1M cases in a day, 99% of counties with high transmission & strained healthcare systems. Protect against #COVID19: get vaccinated + boosted, wear a mask & stay home if sick.”

While speaking at a White House Covid-19 Response Team briefing on Wednesday, Walensky said public health officials will monitor “deaths over the next several weeks to see the impact of Omicron on mortality.”

“Given the sheer number of cases, we may see deaths from Omicron, but I suspect the deaths we’re seeing now are still from Delta,” the CDC head revealed.

The Omicron strain became the dominant variant in mid-December and now accounts for an estimated 98.3% of all new cases, according to CDC data. There were 829,209 cases of COVID-19 in the U.S. on Jan. 12 compared to 90,024 cases on Dec. 12.

On Tuesday, Dr. Anthony Fauci acknowledged how transmissible the Omicron variant is and said nearly everyone will contract it.

“Omicron, with its extraordinary, unprecedented degree of efficiency of transmissibility, will ultimately find just about everybody,” Fauci told J. Stephen Morrison – senior vice president of the Center for Strategic and International Studies. “Those who have been vaccinated … and boosted would get exposed. Some, maybe a lot of them, will get infected but will very likely, with some exceptions, do reasonably well in the sense of not having hospitalization and death.”

Also on Tuesday, U.S. Food and Drug Administration acting commissioner Dr. Janet Woodcock said that “most people are going to get COVID.”

“I think it’s hard to process what’s actually happening right now, which is: Most people are going to get COVID,” Woodcock said at a Senate Health, Education, Labor and Pensions Committee hearing. “And what we need to do is make sure the hospitals can still function, transportation, you know, other essential services are not disrupted while this happens.”

South Africa study suggests Omicron infection could boost immunity against Delta variant

Preliminary findings from a study suggest that infection with the Omicron variant of coronavirus could boost a person’s immunity against the more severe Delta variant.

South African scientists at the Africa Health Research Institute in Durban examined 33 unvaccinated and vaccinated individuals who had contracted the Omicron variant, Reuters reported. They found that people who were infected with Omicron developed enhanced immunity to the Delta variant. Their immunity was even stronger if they had previously been vaccinated against COVID-19. The study, which has not yet been peer-reviewed, also finds that Omicron could displace Delta as the dominant coronavirus variant.

“The increase in Delta variant neutralization in individuals infected with Omicron may result in decreased ability of Delta to re-infect those individuals,” the study’s authors said.

Researchers found that neutralization of Omicron increased 14-fold over 14 days after participants were enrolled in the study. They also found there was a 4.4-fold increase in neutralization of the Delta variant. The study’s authors explained the results are “consistent with Omicron displacing the Delta variant, since it can elicit immunity which neutralizes Delta making re-infection with Delta less likely.”

Scientists are optimistic that if Omicron proves to cause less severe disease than Delta, the pandemic may finally end. The ultimate question is whether Omicron is less pathogenic compared to Delta. “If so, then the incidence of COVID-19 severe disease would be reduced and the infection may shift to become less disruptive to individuals and society,” the authors wrote.

There is reason for hope. The wave of Omicron cases experienced in South Africa quickly subsided within weeks after it was first reported, even though only 48.3% of the population is fully vaccinated, according to Our World in Data. Alex Sigal, a professor at the Africa Health Research Institute in South Africa, explained on Twitter Monday that if Omicron behaves as observed in South Africa, it will “help push Delta out” and possibly lead to the end of COVID-19 disrupting our lives.

Previous studies from South Africa have indicated there is reduced risk of hospitalization and severe disease in people infected with the Omicron variant compared with Delta, though the authors caution that some of this is likely due to high population immunity, Reuters reported.

COVID-19 hospitalizations in the U.S. have risen in recent weeks as Omicron variant cases have surged, causing new daily average case records in several states. As of Monday morning, more than 71,000 COVID-19 patients were hospitalized across the U.S., according to the Department of Health and Human Services. At the height of the Delta variant surge this year, more than 100,000 people were hospitalized with COVID-19, according to UPI.

CDC Director Now Says ‘New Data’ Shows Breakthrough Cases in Vaccinated People Can Spread as Much Virus as Unvaccinated

Centers for Disease Control and Prevention Director Dr. Rochelle Walensky is now saying that “new data” shows breakthrough cases in vaccinated individuals can spread as much virus as an unvaccinated person.

The CDC has now changed course yet again and is now calling for fully vaccinated Americans to wear masks indoors in places with “substantial or high” transmission — including “universal masking” in schools.

“In rare occasions, some vaccinated people infected with a delta variant after vaccination may be contagious and spread the virus to others,” Walensky said during a press briefing on Tuesday. “This new science is worrisome, and unfortunately warrants an update to our recommendation.”

Despite giving these new recommendations, the CDC director continued to demand that people go get vaccinated.

“Getting vaccinated continues to prevent severe illness, hospitalization and death, even with delta. It also helps reduce the spread of the virus in our community. Vaccinated individuals continue to represent a very small amount of transmission occurring around the country,” Walensky said.

The CDC had issued guidance earlier this month that suggested vaccinated students and staff were fine to go to school without masks.

“CDC recommends localities encourage universal indoor masking for all teachers, staff, students, and visitors to schools, regardless of vaccination status,” the CDC wrote in a summary of the new guidance. “Children should return to full-time in-person learning in the fall with proper prevention strategies are in place.”

Walensky claimed that the news that vaccinated people will still have to wear masks “weighs heavily” on her.

“This weighs heavily on me. I know at 18 months through this pandemic, not only are people tired, they’re frustrated,” Walensky said. “And I know, in the context of all that, it is not a welcomed piece of news that masking is going to be a part of peoples lives who have already been vaccinated.”

She claimed that vaccinated people will have to wear masks again due to people who opted not to take the jab — continuing to pit the nation against each other.

“This moment, and most importantly, the associated illness, suffering and death could have been avoided with higher vaccination coverage in this country,” Walensky said.

Walensky added that if more people don’t get vaccinated, the virus could mutate to “potentially evade our vaccines.”
