    v: In countries with low levels of measles transmission MCV1 may be administered at 12 months of age. As a general rule, live vaccines should be given either simultaneously or at intervals of 4 weeks. An exception to this rule is OPV, which can be given at any time before or after measles vaccination without interference in the response to either vaccine.

    v: In countries with low levels of measles transmission, administration of MCV2 at 15-18 months of age ensures early protection of the individual. The minimum interval between MCV1 and MCV2 is 4 weeks. As a general rule, live vaccines should be given either simultaneously or at intervals of 4 weeks. An exception to this rule is OPV, which can be given at any time before or after measles vaccination without interference in the response to either vaccine.
