Herd immunity against the coronavirus will only develop when its spread is limited. According to new research, previously estimated figures for this are proving to be incorrect. Very few people can be said to have developed immunity to Covid-19 only after the infection is limited. Herd immunity means that people develop the ability to fight disease on a large scale. Many countries of the world trust this system for the Covid-19 epidemic that develops automatically in the human body. According to research, this system may prove more effective in countries like India.

Many scientists, including Nottingham University in Britain, believe that herd immunity will develop in someone only when they come in contact with the disease. Natural immunity will develop after exposure to this disease. They say that when the large community becomes immunized for the disease, the graph of infection will slow down and the chain of infection will also be broken.

Herd immunity means when a group of people become immune to a disease, that is, they will develop immunity to the disease. According to scientists, socially more active people are at higher risk of infection and once infected they can infect more people. Researchers said that the level of herd immunity is low when the immunity develops due to the disease. This immunity is stronger if developed through a vaccine.
