What is herd disc?

Herd disc (or herd immunity) refers to a situation where a large percentage of a population becomes immune to a particular infectious disease, either through vaccination or previous exposure, which can help protect those who are not immune.

Herd immunity is typically achieved when around 70-90% of the population is immune to a disease, making it difficult for the disease to spread and infect others. This is especially important for vulnerable populations who may not be able to receive vaccines, such as newborns, pregnant women, and individuals with weakened immune systems.

Herd immunity is a key component of public health strategies for controlling and preventing the spread of infectious diseases, and plays a vital role in reducing the overall impact of outbreaks and epidemics. Vaccination campaigns are a common way to achieve herd immunity and protect the population from vaccine-preventable diseases.
