Herd Immunity | Community Health

Herd immunity is a crucial concept in public health that refers to the protection of a population from infectious diseases when a sufficient percentage of individuals have become immune, either through vaccination or previous infections. This collective immunity helps to prevent the spread of diseases and can ultimately lead to their eradication. According to the [[world-health-organization|World Health Organization]] (WHO), herd immunity has been instrumental in reducing the incidence of many diseases, including [[measles|measles]] and [[polio|polio]].
