Measles vaccine is a live attenuated vaccine that protects against measles, with nearly all recipients who fail to develop immunity after one dose developing it after a second. When vaccination coverage in a population exceeds 92 percent, outbreaks of measles typically no longer occur. The vaccine was first introduced in 1963, when the Edmonston-B strain of measles virus was turned into a vaccine by John Enders and colleagues and licensed in the United States, and in 1968 an improved and even weaker strain was developed by Maurice Hilleman and colleagues, becoming the only measles vaccine used in the United States since then. The vaccine is available alone or in combinations such as the MMR vaccine and the MMRV vaccine, and about 86 percent of children globally had received at least one dose as of 2018. It is on the World Health Organization's List of Essential Medicines.
Facts
FAQs
Can the measles vaccine still help after someone has been exposed to measles?
Yes. Vaccination within 72 hours of exposure may give some protection or a milder illness.
It can. The Centers for Disease Control and Prevention says a person who gets the MMR vaccine within 72 hours of first being exposed to measles may get some protection against the recent exposure or have a milder illness. The agency also says it is not harmful to get the MMR vaccine after exposure, and that the shot gives long-term protection against measles, mumps and rubella as well. Someone without immunity who is exposed should talk with a doctor about vaccination.
