'Uncertain': WHO on vaccine effectiveness on India-dominant variants

The World Health Organisation in its weekly update  said that the new strains of the Covid variant found in India are deadlier and more infectious. The world health body said B.1.617 variant first detected in India in October and now found in 44 countries, has a higher rate of transmission and reduced susceptibility to neutralisation antibodies

It also said the potential impact of these mutations on the effectiveness of vaccines is uncertain. Some studies revealed the Pfizer and Moderna vaccines have shown "reduced effectiveness" against variants in India, the WHO said.

According to WHO, the B.1.17 variant found in UK and the India-dominant B.1.617 will wane, but there are more dangerous mutations of the B.1.617 now.
