Is an early second dose of MMR vaccine recommended for children?
No, except in unusual circumstances. If a child who has received one dose of MMR vaccine is exposed to mumps before receiving a second dose, the Health Department recommends administering the second dose early. The second dose can be safely administered as early as 28 days after the first, but it may not provide immediate protection. Because of a current outbreak of mumps, the Health Department recommends that children living in Brooklyn receive their second dose of MMR vaccine early. The early second dose is valid for school records.
