The paper describes unpublished data showing that perhaps fully vaccinated people are distributing the delta variant at exactly the same rate as unvaccinated people.
CDC Director Dr. Rochelle Walenksy confirmed the authenticity of the document. The document was first reported by The Washington Post.
“I think people should understand that we are not panicking unnecessarily. It’s serious,” he told CNN. – It is one of the most contagious known viruses. Measles, chickenpox, delta variant. They are in the same category in terms of infectivity. “
On Friday, the CDC plans to release data that will back up the much-debated Dr. Mr. Walenksy’s decision to change the recommendations for people who have been fully vaccinated.
He said Tuesday that the CDC recommends that even fully vaccinated people wear protective masks indoors with prolonged or high viral transmission.
The CDC slide set states that the infectivity of the delta variant is roughly equivalent to chickenpox, with one infected person infecting eight or nine others on average. The initial variant of the coronavirus was similar to the cold virus in terms of infectivity, with one person on average infecting two people. This infectivity is called R0.
“When it comes to diseases with an R0 of eight or nine, there are not that many,” CNN explained. R. Walensky.
If vaccinated people are still infected, they have the same number of virus particles as unvaccinated people. This means that vaccinated people can infect others in the same way as unvaccinated infected people, writes CNN.
“The key conclusion is that, unlike other strains of coronavirus, vaccinated people, even if they don’t develop COVID-19, still get infected and spread the delta variant at a rate similar to that of unvaccinated infected people,” CNN said. Dr. Walter Orenstein, director of the Emory Vaccine Center.
Still, the document says that vaccinated people are significantly safer.
“Vaccines prevent more than 90 percent. Cases of severe disease, but may be less effective in protecting against infection or transmission, he says.” Therefore, despite vaccination, there is likely to be a greater spread of the delta strain in the communities. “
The document also notes that vaccines reduce the risk of serious illness or death by 10 times and the risk of infection by three times.
The slide set also cites three reports showing that the delta strain, also known as B.1.617.2, may be causing a more serious form of COVID-19.
The CDC proposes “acknowledging that the war has changed” and recommends introducing a vaccination requirement and requiring everyone to wear face masks.
The virus is rampant again in the United States, especially in areas where fewer people have been vaccinated.
