How Does Immune Modulation Influence Herd Immunity?
Herd immunity occurs when a significant portion of a population becomes immune to an infectious disease, thereby providing indirect protection to those who are not immune. Immune modulation through vaccination is a key factor in achieving herd immunity. By increasing the number of immune individuals, the overall transmission of the pathogen is reduced, protecting vulnerable populations such as infants, the elderly, and immunocompromised individuals.
