1.What’s it?
Herd immunity is when a large section of a population is immunized to a disease- either through a vaccination or due to having the actual illness and recovering.
2.What’s the problem?
The problem is there isn’t a vaccine, which means inducing herd immunity becomes a challenge;
it would mean deliberately introducing the virus into the population.
3.Feasible?
The Princeton study advocates releasing the pathogen in a controlled manner by lifting the lock down and allowing the workforce to resume their jobs, predicting that 60% of the Indian population will develop herd immunity by November.
4.Risk?
However, a study by Los Alamos National Laboratory, US – not specific to India – said 82% of the population needs to be immune before herd immunity kicks in. The risk is for people over 65, who are most vulnerable to COVID-19.
5.Will it work?
Theoretically, yes. Measles – extremely contagious – with one person able to infect 18 others, needed at least 95% of the population to become immune in order to develop herd immunity. It was declared eliminated in 2000. COVID-19 is much less contagious.
6.The challenge
Comorbidities – pre-existing conditions that are worsened by the infection – are high in India.The country has the second highest number of diabetics in the world and scores of other problems like heart and respiratory illnesses.
