Proposal to separate combination vaccine draws caution from health experts

A government official has proposed splitting the MMR vaccine—which currently protects against measles, mumps, and rubella in a single injection—into three separate shots. Public health experts warn the change would complicate immunization schedules and likely reduce vaccination compliance, as patients may skip doses across multiple appointments. Medical organizations emphasize the combined vaccine's established safety record and note that separate schedules increase disease risk in the population.
