In this column, the author deals with the issues of surging delta variant, waning immunity (after infections and vaccinations), possible need for a booster (third) vaccine dose, and signs of an incipient third wave.
Currently, the delta (and possibly other variants) is fully exploiting two things: our inappropriate behaviour such as crowding and violation of standard preventive protocols and the low rate of vaccinations in most parts of the world.
Manipur Chief Minister N Biren Singh said that patients under home isolation will be provided additional medicines useful in treatment of the variant and also 20 triple layer masks each, hand sanitizers with extra medicines from Friday.
Certain measures would help prevent, ward off, or mitigate the third wave. One is to massively speed up vaccinations.
