This is a very controversial topic and everyone has different views on it. I have just put down my opinion about it and it doesn't mean that it is good, or bad either. We all can have different views on this and that's completely alright. Please don't take any offence from this blog post.
Firstly, what is herd immunity?
Herd immunity is also called community immunity and herd or group protection. It occurs when a 60 per cent of the community is deemed immune to a disease (through vaccination and/or prior illness), making the spread of this disease from person to person unlikely. This can happen when many people contract the disease and in time build up an immune response to it (natural immunity). It may also occur many people are vaccinated against the disease to achieve immunity.
So, while all other countries are fighting to keep a stable lockdown and prevent public gatherings, Sweden has its own way of dealing with the situation. Sweden has not imposed any restrictions on its people. People are following social distancing but not all of them. The public life is as open as possible. It was aimed at allowing some exposure to the virus in order to build immunity among the general population while protecting high-risk groups like the elderly. Countries have been seen struggling recording lower cases and then rising them back to 100 while Sweden has kept it in the range of 30, metaphorically. Under such a policy the virus should actually be allowed to spread. The logic is that this will not affect most people seriously; those who get it, and get over it, can then get on with their lives and with their jobs. Such a risky policy, seems to be working according to Sweden’s chief epidemiologist.
Can India do it?
It's highly unlikely. We have been in lockdown for a long period and it's not likely for the government to change its policy and let the virus spread. Moreover, there will be other controversies and questions arising at the government which will prevent it from taking such a decision or making such an amendment.
What happens if we do it?
The major part of the Indian population is youth, who have a higher immunity and better resistance to diseases. If we move forward with this, we will most likely allow the youths to continue with their lives while maintaining social distance and keeping our senior citizens under lockdown. We might actually develop immunity towards the virus.
However, the risks are too high. If it doesn't work, we will be facing a bigger issue under an overloaded medical system and crippling economy. The numbers will rise exponentially and the spread will be faster than ever because of how densely populated India is.
Until the government decides any policy change or amends anything, it's necessary that we keep ourselves and everyone around us safe. Please don't leave your home unless absolutely necessary.
