Scientists reported that the immune cells developed by the human body against the new type of coronavirus (Kovid-19) also protect against the types of the virus that occur in the UK, South Africa and Brazil.

Researchers of the US National Institute of Allergy and Infectious Diseases (NIAID), in their research published in the journal “Open Forum Infectious Diseases”, determined that in individuals infected with the first type of Kovid-19, cell-level immune responses also occur against later types.

The researchers, who took blood samples from 30 people who were infected in the first form of Kovid-19, observed that the “CD8 +” type immunity-assisting T cells were also effective against the species that emerged with the mutation of the virus.

“The data show that the first variants fully recognize other major variants of the T cell response in those infected,” said Andrew Redd, a professor at the Johns Hopkins University School of Medicine, who led the study. used the expression.

Previously, some studies of antibodies produced by the body against the virus have shown that antibodies developed against the original version of the virus have limited effectiveness against later variants. The findings of the new research focusing on cell-level immune responses point to the presence of basic immune protection against different types of Kovid-19.
