The measles vaccine is a live attenuated virus vaccine.
There are few absolute contraindications to the vaccine, and the adverse effects are generally minor and transient.
Seroconversion appears 10 to 14 days after vaccination.
The seroconversion rate after one dose of vaccine ranges from 85 to 95%, depending on the age at administration.
Measles vaccination is included in all national immunisation programmes.
Vaccination should be done early (starting at age 9 months). Any child not vaccinated before 1 year of age should be protected as soon as possible, and a second dose given during the second year of life (at least 4 weeks after the first).
In certain high-risk situations (malnutrition, HIV infection, population displacement, etc.), it is recommended that children be vaccinated starting at age 6 months (dose 0) and then given the two doses as specified in the immunisation schedule.
Getting and maintaining high immunisation coverage are essential to avoid outbreaks.
