A groundbreaking preprint paper by the prestigious Oxford University Clinical Research Group, published Aug. 10 in The Lancet, includes alarming findings devastating to the COVID vaccine rollout.
The study found vaccinated individuals carry 251 times the load of COVID-19 viruses in their nostrils compared to the unvaccinated.
While moderating the symptoms of infection, the jab allows vaccinated individuals to carry unusually high viral loads without becoming ill at first, potentially transforming them into presymptomatic superspreaders.
This phenomenon may be the source of the shocking post-vaccination surges in heavily vaccinated populations globally.
The paper’s authors, Chau et al, demonstrated widespread vaccine failure and transmission under tightly controlled circumstances in a hospital lockdown in Ho Chi Minh City, Viet Nam.
The scientists studied healthcare workers who were unable to leave the hospital for two weeks. The data showed that fully vaccinated workers — about two months after injection with the Oxford/AstraZeneca COVID-19 vaccine (AZD1222) — acquired, carried and presumably transmitted the Delta variant to their vaccinated colleagues.
They almost certainly also passed the Delta infection to susceptible unvaccinated people, including their patients. Sequencing of strains confirmed the workers transmitted SARS-CoV-2 to one another.
This is consistent with the observations in the U.S. from Farinholt and colleagues, and congruent with comments by the director of the Centers for Disease Control and Prevention conceding COVID-19 vaccines have failed to stop transmission of SARS-CoV-2.
On Feb. 11, the World Health Organization indicated the AZD1222 vaccine efficacy of 63.09% against the development of symptomatic SARS-CoV-2 infection. The conclusions of the Chau paper support the warnings by leading medical experts that the partial, non-sterilizing immunity from the three notoriously “leaky” COVID-19 vaccines allow carriage of 251 times the viral load of SARS-CoV-2 as compared to samples from the pre-vaccination era in 2020.
Thus, we have a key piece to the puzzle explaining why the Delta outbreak is so formidable — fully vaccinated are participating as COVID-19 patients and acting as powerful Typhoid Mary-style super-spreaders of the infection.
Vaccinated individuals are blasting out concentrated viral explosions into their communities and fueling new COVID surges. Vaccinated healthcare workers are almost certainly infecting their coworkers and patients, causing horrendous collateral damage.
Continued vaccination will only make this problem worse, particularly among frontline doctors and nurses workers who are caring for vulnerable patients.
Health systems should drop vaccine mandates immediately, take stock of COVID-19 recovered workers who are robustly immune to Delta and consider the ramifications of their current vaccinated healthcare workers as potential threats to high risk patients and coworkers.
