The delta mutation proved to be more potent than the new coronavirus variant A.30, which in laboratory conditions was able to bypass antibodies arising from vaccination.
The super variant, as it was initially reported, was discovered by German scientists. Eventually, however, the more virulent delta mutation proved far more dangerous than A.30, according to a study in the scientific journal Nature.
Scientists have identified only four cases of the new variant in the world, in Tanzania, where it is believed to have originated, Angola and Sweden, with none appearing in the last five months.
According to Israeli scientists, A.30 apparently can not spread rapidly.
“For any new coronavirus variant, three things need to be examined: whether it spreads quickly, whether it causes more severe disease, and whether it is able to bypass the immune system response,” explained Professor Cyrille Cohen of Bar Ilan University.
“Vaccines are effective against the alpha, gamma, and delta variants. The beta, also known as the South African variant, appears to be more resistant to vaccines but is not as
