Herd Immunity Can Contain COVID 19?

One best way of containing the coronavirus pandemic merely is giving vaccination to the people. The experiments being done by a few countries like Russia and Britain on the corona vaccine are on the final stages. 

However, there is one more way to contain the mass spread of the coronavirus and that's called 'Herd Immunity'. 

Herd Immunity is a form of indirect protection from infectious disease that occurs when a large percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby providing a measure of protection for individuals who are not immune. In a population in which a large proportion of individuals possess immunity, such people being unlikely to contribute to disease transmission, chains of infection are more likely to be disrupted, which either stops or slows the spread of disease. The greater the proportion of immune individuals in a community, the smaller the probability that non-immune individuals will come into contact with an infectious individual, helping to shield non-immune individuals from infection. 

Say, for example, someone who's infected with a particular virus typically transmits it to two others. The chances of that person passing it on to others would be lower if half the population is already immune.
