Why is the world experiencing such a “prominent outbreak” of the Delta variant when so many people have been vaccinated?

Cardiologist Dr. Peter McCullough addressed those questions and more on the “RFK Jr. The Defender Podcast.”

New research shows people who are vaccinated against COVID are more susceptible to the Delta variant, said McCullough, pointing to a pre-print study by the prestigious Oxford University Clinical Research Group published Aug. 10 in The Lancet.

The paper’s authors demonstrated widespread vaccine failure and transmission under tightly controlled circumstances in a hospital lockdown in Ho Chi Minh City, Viet Nam. The study found vaccinated people carry 251 times the viral load of SARS-CoV-2 in their nostrils compared to the unvaccinated.

“They had an outbreak and they locked down the hospital where the workers could not get out,” said McCullough. “They were assiduously checking the workers and testing them for COVID, as well as doing sequencing.”

The researchers found workers were still getting COVID during the lockdown period, said McCullough, and they were passing it to one another.

The study’s big finding is their calculation of viral load, McCullough said:

“This group had actually calculated viral load from oral and nasal secretions in the past. The viral load was 251 times that of the previous unvaccinated era where they had used the same methodology. So, they had previous workers and patients who had COVID-19 before any exposure to the vaccines. And now the vaccinated were carrying a massive viral load and passing it to one another.”

The efficacy for the Pfizer vaccine is measured as being anywhere from 17% to 42% effective.

“These levels are far below the 50% regulatory standard to even have a vaccine on the market,” said McCullough.

Regardless of the variant or the vaccine, McCullough said the bottom line is that “the vaccines are failing.”
