Variant strains, waning immunity render Covid-19 herd immunity impractical hope

(TibetanReview.net, Feb23’21) – The Covid-19 pandemic, which first broke out in the central Chinese city of Wuhan in late 2019, with Beijing brutally suppressing information about it then, and thereby allowing its silent spread, has now killed more than 500,000 people in the USA. This is more than the number of Americans killed in World War I, World War II, and the Vietnam war, noted the New York Times and the BBC News Feb 23.

And amid fears that India could be headed for a second wave of Covid-19 pandemic, a total of 1,14,24,094 vaccine doses have been administered to 75,40,602 healthcare workers and 38,83,492 frontline workers till Feb 22 evening, reported the PTI new agency Feb 22.

Herd immunity is “very difficult” to achieve and should not be thought of in “practical terms” in India, especially in the times of “variant strains” of the Covid-19 virus and “waning immunity”, the ndtv.com Feb 21 earlier cited AIIMS director Randeep Guleria as saying.
