The Lancet preprint specifically states: "Viral loads of breakthrough Delta variant infection cases were 251 times higher than those of cases infected with old strains detected between March-April 2020." A "breakthrough case" is one who contracts the virus after being fully vaccinated. ? TN Editor
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.
