What in your own words is community immunity?

Community immunity, often referred to as herd immunity, occurs when a significant portion of a population becomes immune to a contagious disease, either through vaccination or previous infections. This widespread immunity helps protect those who are unable to be vaccinated, such as individuals with certain medical conditions or Allergies, by reducing the overall spread of the disease. Consequently, even those who are not immune are less likely to be exposed to the infection, thereby decreasing the likelihood of outbreaks.
