What is the goal of herd immunity?

The goal of herd immunity is to protect the population by reducing the spread of disease through vaccination. When a significant proportion of a community is vaccinated, it creates a barrier that limits the transmission of infectious diseases. This is especially important for those who cannot be vaccinated, such as infants, the elderly, or individuals with certain health conditions, as they rely on the immunity of the surrounding population to decrease their risk of exposure.

Achieving herd immunity is crucial for controlling outbreaks and preventing diseases from spreading within the community, contributing to overall public health. It helps to lower the likelihood of outbreaks, indirectly safeguarding individuals who are vulnerable or cannot receive vaccines for medical reasons.
