On this Monday, A World Health Organization (WHO) epidemiologist said that Covid-19 vaccines are showing signs of reduced efficacy against the Delta variant of coronavirus.
The WHO official said that in the oncoming days, there might be a “constellation of mutations” which means that there is a possibility that vaccines will lose their potency against fighting the coronavirus.
However, right now the vaccines are still effective at preventing severe illness and death.
The Delta plus variant formed because of a mutation in the Delta or B.1.617.2 variant. both the Delta and the Delta plus was first identified in India. These two variants are considered to be the most severe and transmittable Covid-19 coronavirus variants up to date.
