A vaccine that protects against measles has been shown to wane very slowly over time but still remains highly effective against the contagious disease, scientists have said.

More than 95% of people who have had two doses of the measles, mumps and rubella vaccine (MMR vaccine) – which was introduced in 1988 – are protected for life, findings published in the journal The Lancet Public Health show.
