Update: Meningococcal Vaccine Recommendations
March 18th, Chicago Department of Public Health.
The Chicago Department of Public Health (CDPH) is investigating a new case of invasive meningococcal disease (IMD) caused by Neisseria meningitidis serogroup C reported in March 2016, 9 months following the last case tied to a Chicago-area outbreak of serogroup C IMD during the summer of 2015. This brings the total number of serogroup C IMD cases in the Chicago metropolitan area to 8 since May 2015. All serogroup C cases have occurred among men who have sex with men (MSM), and a majority have been HIV positive.
CDPH continues to recommend that all MSM receive meningococcal conjugate vaccine. Most adults only need one dose for adequate protection but MSM who are living with HIV should receive 2 doses, separated by 8 weeks (i.e., at 0 and 2 months).
Persons at increased risk of meningococcal disease require revaccination every 5 years as long as the person remains at increased risk.
Free vaccinations are available at CDPH Fast-track clinics and locations listed here. Providers or patients may also directly call 311 to obtain locations where vaccine is accessible for both insured and uninsured individuals.
Additional information from the Centers for Disease Control and Prevention about N. meningitidis infection and meningococcal vaccines can be found here.
Please remember to report cases of IMD to CDPH immediately. To report a suspect or confirmed case of meningococcal disease, please call 312-746-5377 or 312-746-5925 during business hours; during non-business hours, call 311 and ask for the communicable disease physician on-call.
