Keokuk, IA – Hundreds of doses of the MMR vaccine are being sent to Southeast Iowa to help combat the outbreak of mumps. Lee, Des Moines, and Henry Counties will each receive 400 doses. So far, there have been more than a dozen documented cases of mumps in the three counties. Dr. David Wenger-Keller is the Chairman of the Lee County Board of Health. He says a vaccination clinic will be held at the county health department's Fort Madison office, next Thursday (4/27) at noon. To be immune to mumps, Wenger-Keller says one must have either received 2 doses of the MMR vaccine or contracted the actual virus. He says a clinic will also be held in Keokuk, next week, though no time or date has been set.
