Response in English: Herd immunity, also known as community immunity or population immunity, is an epidemiological concept that describes how a population as a whole is protected from a contagious disease when a significant proportion of its members become immune to the disease. This can occur either through vaccination or through previous exposure and recovery from the infection. The idea behind herd immunity is that once enough people are immune to a disease, it becomes difficult for the disease to spread within the community, as there are fewer susceptible individuals for the disease to infect. Consequently, even those individuals who are not immune are indirectly protected, as the likelihood of an outbreak decreases. For example, when a high percentage of a population is vaccinated against a disease, it becomes much less likely that an unvaccinated individual will come into contact with someone who is infected, thus reducing the likelihood of an outbreak. The threshold for herd immunity varies for different diseases, depending on factors such as how infectious the disease is, but it generally ranges from 70 to 90 of the population being immune.It is important to note that herd immunity is a population-level phenomenon and does not necessarily offer complete protection to every individual within the population. Therefore, it is crucial to continue practicing good hygiene, social distancing, and other measures to prevent the spread of disease, even when herd immunity has been reached. .
