    ■  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 immunization 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.

     

      In certain high-risk situations (malnutrition, HIV infection, population displacement, etc.), it is recommended that children be vaccinated starting at age 6 months and given a second dose at age 9 months.

     

      Administering a second dose of measles vaccine and getting high immunization coverage are essential to avoiding outbreaks.
