The recommended age for initiating Measles-Containing Vaccine (MCV) depends significantly on the level of measles transmission within a country.
In countries characterized by low levels of measles transmission, the risk of early-life infection is generally reduced. Consequently, the vaccination strategy focuses on achieving high coverage with the standard immunization schedule rather than prioritizing very early, potentially less effective, vaccination.
For countries with low measles transmission, the appropriate age for starting immunization with the first dose of MCV is typically:
This aligns with the standard routine childhood vaccination schedule in many parts of the world. A second dose is usually administered later, commonly between 15-18 months, to ensure long-term immunity.
