Ex-Pfizer Vice President’s claim ‘COVID is effectively over’ termed false

“I believe I have provided more than adequate evidence that a significant proportion (30%) of the population went into 2020 armed with T-cells capable of defending them against SAR-CoV-2, even though they had never seen the virus,” Yeadon wrote.

“This is because they’d been previously infected by one of more common cold-producing coronaviruses. SAGE was naively wrong to assume ‘everyone was susceptible’,” he wrote.

Health Feedback said that “the implications for immunity are still unknown.”

“Although scientific studies found that some people who never had COVID-19 have a certain type of immune cell (memory T cell) that can recognize SARS-CoV-2, the implications for immunity are still unknown,” the nonprofit fact-checker said.

“More studies are needed to ascertain the role of memory T cells in immunity to COVID-19.,” it added.

“A person’s antiviral immune response is comprised of several components, including antibodies, which can bind to certain proteins on the surface of the virus and prevent it from infecting cells. One of the key goals of COVID-19 vaccines is to stimulate the production of antibodies that prevent infection,” Health Feedback said.

Pfizer last week said that it is seeking emergency approval from US regulators for its COVID-19 vaccine, which has shown 95 percent efficacy in a totality of two data sets.
