The World Health Organization’s (WHO) top scientists said on Monday that a Corona vaccine is expected to be available for submission to regulators for approval in December or early 2021.
When asked by Anadolu about a possible pandemic vaccine schedule, Dr. Soumya Swaminathan: “It is very exciting to see progress in clinical trials around the world.”
He added, “As you know, we now have about 40 vaccine candidates at some point in clinical trials, and 10 of them are in Phase 3, a final stage clinical trial looking at both efficacy and safety.”
He said the earliest time the vaccine will enter the market and be presented to regulators is “from December 2020, early 2021.”
Dr. Mariangela Simao, WHO’s director of drug and health product access, said vaccines developed had to be approved in the country where the research was conducted.
“And we also have the production capacity that needs to be available for use at the state level. There are many, many steps to take once the Phase 3 tests are actually completed,” Simao added. that WHO is working very closely with national regulatory authorities.
Director General of WHO, Dr. Tedros Gebreesus, opposed “the concept of achieving so-called herd immunity by spreading viruses”.
He said livestock immunity is a vaccination concept where a population can be protected from certain viruses once the immunization threshold is reached.
Tedros said that in the history of public health, herd immunity was never used as a strategy to respond to an outbreak or even a pandemic.
He stated that about 95% of the population must be vaccinated for measles immunization.
“The remaining 5% will be protected from the fact that measles does not spread among those vaccinated,” said Tedros.
“This is problematic both scientifically and ethically. First, we don’t know enough about immunity to COVID-19.
“Most people infected with the virus that causes COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or persistent that immune response is, or how it differs in different people. We have some clues, but we don’t have any. The whole picture. “
Tedros said he has no immunity to the new coronavirus. Reuters
