Detailed explanation-1: -Herd immunity occurs when the majority of a population is immune to a disease or virus. Otherwise known as community immunity 1, it helps to slow the spread of infectious diseases in two ways : People contract the disease and develop an immune response. People are vaccinated.
Detailed explanation-2: -Herd immunity, or community immunity, means there are enough people immunised in the community to slow or stop the spread of disease. If enough people in the community get immunised against a disease, the infection can no longer spread from person to person. The disease can die out altogether.
Detailed explanation-3: -Herd immunity is the idea that when many people are immune to a contagious infection, usually by getting a vaccine, it’s harder for that infection to spread in a community. Vaccines teach the body to recognize and fight germs so we can’t get sick from them in the future. This helps us become immune to infections.
Detailed explanation-4: -Why herd immunity is important. Herd immunity can protect a population from a specific disease, even if a small part of a population isn’t immune-for example, children and those with a severely weakened immune system. Deciding to get vaccinated means protecting you and those who can’t protect themselves.
Detailed explanation-5: -Active Immunity Natural immunity is acquired from exposure to the disease organism through infection with the actual disease.
