Vaccination coverage refers to the percentage of a population that has received specific vaccines. It is an important measure for public health, as higher coverage rates can lead to herd immunity, which protects those who cannot be vaccinated, such as infants or individuals with certain medical conditions. Monitoring vaccination coverage helps health authorities identify areas with low immunization rates, allowing them to implement targeted campaigns. This is crucial for preventing outbreaks of vaccine-preventable diseases, such as measles or influenza, and ensuring the overall health of the community.
