As COVID Surges Among Fully Vaccinated, CDC Fails to Properly Track Breakthrough Cases

Via Children’s Health Defense


As the number of breakthrough COVID cases continues to climb, there is growing concern fully vaccinated people may be more vulnerable to serious illness than previously thought — and some fully vaccinated people now sick with the virus are speaking out.

According to the most recent data from the Centers for Disease Control and Prevention (CDC), there were 9,716 breakthrough cases resulting in hospitalization or death as of Aug. 16. However, the agency states those numbers are underreported. On May 1, the CDC made a decision to stop tracking all breakthrough cases and instead only track cases in the fully vaccinated that resulted in hospitalization or death.

That leaves public health officials without the full data that can answer questions as the new Delta variant spreads.

In an interview with PBS News HourJessica Malaty Rivera, an infectious disease epidemiologist and research fellow at Boston Children’s Hospital and former science communications lead at the COVID Tracking Project, said not tracking breakthrough data with as much granularity as we would hope is “basically creating blind spots in our understanding of the true impact of the virus, especially the variants that are circulating so widely in the United States.”

Rivera said she has yet to see an explicit explanation for why the CDC stopped tracking all breakthrough cases. “I’ve heard rumors of things like lack of resources, lack of funding, lack of staff. But to me, it seems pretty, from an epidemiology standpoint, not defensible,” she said.

breakthrough case refers to a person who is diagnosed with COVID after being fully vaccinated. A person is considered fully vaccinated 14 days after receiving the second dose of either the Pfizer or Moderna COVID vaccine, or two weeks after receiving the single-dose Johnson & Johnson (J&J) vaccine.

The New York Times recently published data from seven states — California, Colorado, Massachusetts, Oregon, Utah, Vermont  and Virginia — that keeps particularly detailed records on breakthrough cases.

Analysis showed that in six of the states, breakthrough infections made up 18% to 28% of all newly diagnosed cases of COVID in the past several weeks, and 12% to 24% of all COVID-related hospitalizations, with reported deaths higher than the CDC’s original estimate of .5%.

The figures on non-hospitalized breakthrough infections are also assumed to be underestimations since many fully vaccinated people who become infected may not feel sick enough to be tested for the virus, The Times reported.

About 30% of the new COVID cases in Los Angeles are breakthrough cases, Deadline reported. The number is up from 13% in July and 5% in April.

As of Aug. 17, more than 12,500 fully vaccinated Massachusetts residents had tested positive for COVID and an additional 18 had died, according to NBC Boston.

Fully vaccinated celebrities, elected officials speak out after getting COVID

Melissa Joan Hart, the former “Sabrina the Teenage Witch” star is “really mad” she has a breakthrough case. Hart shared on Instagram Aug. 19 that despite being vaccinated, she got COVID.

“I never do videos but I feel like this is important,” Hart, who recently moved to Tennessee, told her 1.6 million followers. “I got COVID. I am vaccinated. And I got COVID. And it’s bad. It’s weighing on my chest, it’s hard to breathe.”

Heart’s oldest son, Mason, also tested positive for COVID, as did her youngest son — who experienced no symptoms. Her middle child tested negative and her husband is still waiting for his results.

Hart blamed the vaccine’s failure to protect her on her kids not having to wear masks in school. Tennessee Gov. Bill Lee on Aug. 16  signed an executive order allowing parents to choose whether their child should wear a mask in school.

“I’m mad, really mad,” Hart said, “because we tried, and we took precautions and we cut our exposure by a lot. But we got a little lazy, and I think as a country we got lazy. And I’m really mad that my kids didn’t have to wear masks at school because I’m pretty sure that’s where this came from.”

Celebrity Hilary Duff, revealed she had COVID on Instagram Aug. 20. Duff said she was experiencing a bad headache, brain fog, sinus pressure and a loss of taste and smell despite being vaccinated.

“That Delta … she’s a little b****,” Duff wrote, referring to the variant that accounts for 98.8% of current U.S. infections, according to the latest data from the Centers for Disease Control and Prevention (CDC).

Slipknot singer Corey Taylor, 47, was devastated after testing positive for COVID and was forced to call off his upcoming appearance at a Michigan pop culture convention this weekend, Rolling Stone reported.

“I wish I had better news,” said Taylor in a recorded video message last week on Facebook. “I woke up today and tested positive and I’m very, very sick.”

The singer assured fans he “should be okay” because it’s the flu and he’s vaccinated.

Rev. Jesse Jackson, and his wife, Jacqueline, remained under doctors’ observation Monday at a Chicago hospital after getting COVID. Both were “responding positively to treatments,” Politico reported.

The couple was admitted to Northwestern Memorial Hospital Aug. 20 so physicians could carefully monitor their condition, one of the couple’s five children, said in a statement.

Jackson, a Chicago civil rights leader, was fully vaccinated and received his first dose in January during a publicized event where he urged others to receive the vaccine as soon as possible.

Three U.S. senators — John Hickenlooper (D-Colo.), Angus King (I-Maine) and Roger Wicker (R-Miss.) — announced Aug. 19 they tested positive for COVID despite being fully vaccinated, CBS News reported.

“Despite taking precautions and receiving the vaccine, this morning I tested positive for COVID-19,” King tweeted. “While I am not feeling great, I’m definitely feeling much better than I would have without the vaccine.”

The news came days after Texas Gov. Greg Abbott, who also was fully vaccinated, tested positive for COVID.

Illinois state Sen. Dan McConchie announced Aug. 21 he had a “breakthrough” case of COVID. The Republican leader of the Illinois Senate said in a statement he was vaccinated against the virus this spring, and he urged others to get vaccinated.

COVID data show waning immunity

Of 514 patients in Israel hospitalized with COVID as of Aug. 15, 59% were fully vaccinated, according to an article from Science. The article cited national data tracked by Israel’s largest health management organization. The figures suggest breakthrough infections may be more common than previously thought.

Most of the vaccinated patients who were hospitalized, about 87%, were at least 60 years old.

“This is a very clear warning sign for the rest of the world,” said Ran Balicer, CIO at Clalit Health Services, Israel’s largest health maintenance organization. “If it can happen here, it can probably happen anywhere,” Balicer told Science.

Israel has one of the world’s highest COVID vaccination levels with 78% of the population over age 12 fully vaccinated — mostly with Pfizer’s vaccine. The country now has one of the highest infection rates in the world.

Brian Hooker, Ph.D., P.E., Children’s Health Defense chief scientific officer and professor of biology at Simpson University, said “What we’re seeing is virus evolution 101.”

Hooker said the more a variant deviates from the original sequence used for the vaccine, the less effective the vaccine will be on that variant, which could explain why fully vaccinated people are getting infected with the Delta variant.

This isn’t the case for natural immunity, Hooker explained:

“The vaccine focuses on the spike protein, whereas natural immunity focuses on the entire virus. Natural immunity — with a more diverse array of antibodies and T-cell receptors — will provide better protection overall as it has more targets in which to attack the virus, whereas vaccine-derived immunity only focuses on one portion of the virus, in this case, the spike protein. Once that portion of the virus has mutated sufficiently, the vaccine no longer is effective.”

As The Defender reported Aug 2, vaccinated people may play a key role in aiding the evolution of COVID variants.


According to research published July 30 in Scientific Reports, the highest risk for establishing a vaccine-resistant virus strain occurred when a large fraction of the population has already been vaccinated but the transmission is not controlled.

The data was consistent with a CDC study, also released July 30, which showed vaccinated people may transmit the Delta variant just as easily as the unvaccinated.

According to a pre-print study published Aug. 10 in The Lancet, vaccinated individuals carry 251 times the load of SARS-CoV-2 viruses in their nostrils compared to the unvaccinated.

The study, by the Oxford University Clinical Research Group, demonstrated widespread vaccine failure and transmission under tightly controlled circumstances in a hospital lockdown in Ho Chi Minh City, Viet Nam.
