Measles is not yet "eradicated" worldwide, meaning it still spreads regularly in other countries.

The measles vaccine is highly protective against measles infections of all severity levels.

If a person survives a bout of measles infection, they typically have lifelong immunity.

The measles vaccine provides lifelong immunity against the virus without complications associated with measles.

If you've received two doses of the MMR vaccine, you're considered immune for life in most cases.

About 3% of fully vaccinated people may still develop symptoms after an exposure to the virus.

Measles is one of the most contagious diseases in the world, and because of that, at least 95% of a given population needs to be immune to prevent major outbreaks.

Herd immunity refers to when a high percentage of a population is immune to a disease, making it difficult for the infection to spread.
