Ziqitza Limited Rajasthan - How effective are vaccines against Covid Mutant Variant
Ziqitza Limited says while there is much to learn about emerging variants and how vaccines work against them, there is already much that we know. Headlines on “immune escape” variants may indeed be alarming, but they are also simplistic. The immune system is analogous to a complex machine with many parts and settings. It isn’t a switch that goes between “on” and “off”.
