Why doesn the ACIP recommend MMRV at twelve to fifteen months with the second dose 3 months later?
The recommendation at 4-6 years for the 2nd dose of MMR and varicella vaccines (or MMRV) is consistent with current ACIP school entry recommendations. This is as much a programmatic issue as anything. It is a good time to capture kids before school entry to make sure they are current on all recommended immunizations when exposure risks are very likely to increase. Some providers recommend a routine pediatric visit at 15 months of age. If patients received the first dose of MMRV at 12 months of age, the minimum acceptable interval to the second dose of MMRV is 3 months (12 weeks).
