, ||Herd Immunity not a choice,why?
The early days of the Covid-19 pandemic in India saw the R0 value, a metric that describes how many people are likely to get infected from one patient, climb to 1.83. This led experts to suggest that as many as 60 per cent of the population will have to gain immunity by recovery or vaccination for herd immunity to kick in.
This was an alarming assessment as the 27,67,273 cases recorded in India so far (accounting for approximately 0.2 per cent of the population) have already led to 52,889 deaths. Even the government has warned that, without vaccination, the country can only achieve herd immunity at a high human price.
However, emerging research showing that the body can launch a robust immune response to SARS-CoV-2, the virus that causes Covid-19, even in the absence of previous exposure, along with evidence that antibodies for the disease last in the system for at least six months, points to the fact that achieving herd immunity may be easier than thought.
Herd immunity refers to a concept where enough members of the population are immune to a disease, making it difficult for the pathogen to find new hosts to infect. It is not necessarily achieved with vaccinations alone, and can also be gained if enough people develop antibodies against the pathogen after first contracting it.
If a significant proportion of the population becomes immune to a virus, it will run out of fresh people to infect and the chain of transmission will be disrupted.
