Herd immunity happens when a large part of the population — the herd — is immune to a virus. This can happen either because these people got vaccinated or had already been infected. Herd immunity makes it harder for a virus to spread.So even those who haven’t been sick or vaccinated have some protection.
Herd immunity’, also known as ‘population immunity’, is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection. WHO supports achieving ‘herd immunity’ through vaccination, not by allowing a disease to spread through any segment of the population, as this would result in unnecessary cases and deaths.
Fauci, director of the National Institute of Allergy and Infectious Diseases, said he has estimated 70-85% of the population would need to be vaccinated or immune to reach herd immunity.
Herd immunity makes it possible to protect the population from a disease, including those who can’t be vaccinated, such as newborns or those who have compromised immune systems.
Herd immunity also can be reached when enough people have been vaccinated against a disease and have developed protective antibodies against future infection. Unlike the natural infection method, vaccines create immunity without causing illness or resulting complications.

We are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people. There have also been reports of people infected with COVID-19 for a second time. Until we better understand COVID-19 immunity, it will not be possible to know how much of a population is immune and how long that immunity last for, let alone make future predictions. These challenges should preclude any plans that try to increase immunity within a population by allowing people to get infected.
