Ineffective vaccines: The United States concerned by a new variant of Covid-19

The States is concerned about a possible new wave of Covid-19 caused by the KP.2 variant, currently responsible for the majority of new cases and whose characteristics require particular attention, according to the Centers for Control and Prevention diseases.

The latest vaccines do not protect against KP.2.

According to experts, this new variant presents a mutation in the Spike protein which allows it not to react to vaccines.

“We have a population in which immunity to the virus has weakened, which increases vulnerability to new infections with Sars-CoV-2,” notes Thomas A. Russo, head of the Department of Infectious Diseases at the University at Buffalo Jacobs of Medicine.

“If I look into my crystal ball, I would say that, given the different factors at play with the new mutation, we will probably have a new wave or at least an increase in cases and hospitalizations this summer,” adds the scientist. Director of the Yale University School of Health, Megan Ralley, also believes that a new surge in infections is expected soon.

Finally, a study carried out at Harvard but which has not yet been officially published, would show that not only would the latest vaccines not protect against KP.2, but that this new variant would be more resistant to the immunity acquired during previous infections.
