Updated CDC Measles Infection and Control

CDC published updated interim guidance for measles infection and control in health care settings.

Please note, that the Wisconsin Immunization Program recommends that all healthcare providers have evidence of immunity consisting of 2 doses of MMR vaccine, serologic proof of immunity or a lab-confirmed measles infection.

MMR Adult One Dose Clarification

Recently, the Wisconsin Immunization Registry (WIR) implemented a new Measles, Mumps, and Rubella (MMR) Adult schedule that completes individual’s MMR vaccine series as long as they are 19 years and older and received at least one dose of MMR on or after they turned 12 months old. This is not a new recommendation by the Advisory Committee on Immunization Practices (ACIP) and the Centers for Disease Control (CDC), but rather a new schedule to WIR, as previously WIR did not have a separate adult schedule.

Please note that the MMR one dose recommendation is only for the general healthy adult population, but there are instances where more than one dose of MMR is recommended for someone 19 years and older per ACIP. Such instances include:

  • International travelers
  • Healthcare workers
  • Individuals attending post secondary institutions

WIR does not forecast the second dose in these instances; it will be up to the clinician to determine if the second dose is needed. If more than one dose of MMR is given, WIR will record the doses but it will not be recorded as part of a two dose series.
