The Michigan Department of Health and Human Services (MDHHS) is recommending early measles (MMR) vaccination for infants in select southeast Michigan counties and extending the respiratory syncytial virus (RSV) immunization season through April 30, in response to continued virus activity.
The MDHHS is responding to confirmed measles cases in Washtenaw and Monroe counties and concerns of possible community transmission. Members are encouraged to review MDHHS measles guidance and share the flyer for patients and families. An accelerated measles, mumps and rubella (MMR) dose is recommended for infants ages 6-11 months who live in or travel to Washtenaw, Monroe, Oakland, Jackson, Livingston or Lenawee counties. This recommendation is in effect through May 16.
The MMR vaccine is typically administered beginning at 12 months; infants who receive an early dose will still need to complete the standard two-dose series after their first birthday.
Separately, due to continued increases in RSV-related emergency department visits and hospitalizations among young children, the MDHHS has extended the seasonal administration of RSV monoclonal antibody (mAb) products from March 31 to April 30.
Nationally, most states are also extending the timelines for RSV immunization. Members can read coverage on RSV trends, explore resources from the Association of Immunization Managers and view their RSV season extension map.
Providers are encouraged to continue administering RSV immunizations to eligible children, including:
- Infants ages 0-8 months who have not received a dose.
- Certain high-risk children 8-19 months entering their second RSV season.
Guidance for use remains unchanged aside from the extended timeline, and there is no preferred recommendation between available mAb products for infants under eight months old.
