Vaccination is one of the best ways to create herd immunity.

Herd immunity varies from one disease to another disease as the source, effects and communicable ways are different. The disease that is more contagious will require a greater proportion of the population to be immune to stop its spread.

For example, the measles required 94% of the population to be immune to stop the spread chain.
