Definition of Herd Immunity and How Can we stop spreading COVID-19 with it?

While Corona Virus is spreading in a very bad way which has become a big cause of concern for all the scientists in the world.  According to several scientists, the only Herd Immunity could reduce the spreading of COVID 19 until the proper vaccine will be released.

Now the most important question that comes to everyone mind is

What is Herd Immunity

When most of a community is immune to an infectious disease, this provides indirect protection—or herd immunity (also called herd protection)—to those who are not immune to the disease. If a sufficient community is resistant to the cause of a disease, such as a virus or bacteria, it has nowhere to go. When the herd immunity spread into a large community it makes the spread of disease from individual to individual unlikely. Therefore, the entire population gets secured — not simply the individuals who are immune.
While not every single individual may be immune, the peoples as a whole have protection. Herd immunity protects at-risk populations including each and every people's immune systems are sick and can’t get immunity on their own.

How Do Anyone Obtain Herd Immunity?

There’s mainly two ways to get Herd Immunity – (1) Either they get it by Naturally  OR (2) Through vaccines

Getting it naturally

Herd immunity can also be spread when enough amount of people in the population have recovered from a disease and have developed antibodies against future infection. For example, those peoples who survived the 1918 flu pandemic were later immune to infection with the H1N1 flu, a subtype of influenza A. During the 2009-10 flu season, H1N1 caused the respiratory infection in humans that was usually referred to as swine flu.

Despite this, there are some larger problems with relying on community infection to produce herd immunity to the virus that creates COVID-19.Though scientists have not been yet clear if infection with the COVID-19 virus causes a person immune to future infection.

Getting through Vaccines

A vaccine for the virus that causes COVID-19 would be an excellent suggestion for obtaining herd immunity. Vaccines create immunity without causing illness or resulting in difficulties. Herd immunity performs it possible to protect the population from disease, including those who can't be vaccinated, such as newborns or aged people whose immune systems are weak. Applying the idea of herd immunity, vaccines have successfully controlled deadly contagious diseases such as smallpox, polio, diphtheria, rubella, and many others.
