The MMR vaccine is routinely recommended at 12 to 15 months of age with a second dose given a minimum of 28 days after the first dose. Given the possibility of ongoing community transmission, MDHHS is also recommending that infants ages 6 to 11 months receive an accelerated first dose of measles vaccine if they are in the following groups:
- Residents of Washtenaw, Monroe, Wayne, Oakland, Jackson, Livingston or Lenawee counties.
- Individuals who travel to Washtenaw and Monroe counties.
This recommendation is in effect until Saturday, May 16, which is two incubation periods after the infectious period of the last identified measles case. Any updates to this recommendation will be posted on the MDHHS measles webpage. Infants ages 6 to 11 months of age who receive an accelerated first dose will require two additional doses of the MMR vaccine after 12 months of age to complete the series.
