Third Dose of Mumps-Containing Vaccine Now Recommended in Outbreak Situations
With the increase in mumps outbreaks and outbreak-associated mumps cases in the US, the ACIP now recommends that during an outbreak, one dose of mumps-containing vaccine (MMR or MMRV) be administered to previously vaccinated persons who public health officials identify as being at increased risk.4 The rationale is that, with waning immunity and the high intensity of exposure in close – contact settings typical of many mumps outbreaks, the risk for disease is much higher. Two doses of MMR or MMRV vaccine currently appear to be sufficient for mumps control in the general population. The full ACIP recommendations, Use of a Third Dose of Mumps Virus–Containing Vaccine in Persons at Increased Risk for Mumps During an Outbreak, provide more detailed information on this new recommendation.
Timely reporting of potential mumps cases is vital to the prevention and control of outbreaks. Providers are encouraged to read the October 2017 Rx for Prevention Continuing Medical Education (CME) article, "Recognizing and Managing Mumps in Adults", for details on the presentation, work-up, and management of mumps in adults. For questions regarding mumps or to report, please contact the Los Angeles County Department of Public Health (DPH) Vaccine Preventable Disease Control Program at 213-351-7800 during business hours or the on – call staff after hours at 213-974-1234.
2018 Recommended Immunization Schedules and New Vaccine Information Sheets (VIS)
The Recommended Immunization Schedules for Persons Aged 0 through 18 Years and Adults 19 Years and Older are available on the CDC website: www.cdc.gov/vaccines/schedules/hcp. Please note: when reviewing the schedules, the footnotes contain important information such as vaccine intervals, exceptions to the vaccine schedule, and information regarding vaccination of special populations.
Please share the updated schedules with all health care personnel in your facility, especially those staff who provide immunization services. Please replace any copies of the 2017 schedule posted in your facility with the new 2018 version.
In addition, please note that there are several new VIS from the CDC that should replace older versions:
- Measles/Mumps/Rubella (MMR) VIS
- Measles/Mumps /Rubella & Varicella (MMRV) VIS
- Rotavirus VIS
- Varicella (Chickenpox) VIS
- Live Zoster (Shingles) VIS
- Recombinant Zoster(Shingles) VIS
