"There is currently no evidence that this option causes more severe disease or makes the vaccines currently in use less effective. PHE is conducting laboratory tests to better understand the effect of mutations on the behavior of the virus," it said.
It is noted that all 16 cases of infection with the new strain were found in those who recently returned from abroad. The country's authorities promise to take all necessary measures to prevent the spread of this option.
The WHO reports that the first case of infection with the B.1.621 strain was reported in Colombia in January 2021. Since then, it has been reported in 26 different countries and regions, with almost half of the cases occurring in the United States. So far, this option is being prepared for further monitoring and is not a matter of particular concern to WHO.
