Ask the Experts: Meningococcal ACWY: Contraindications & Precautions

Results (3)

As with all vaccines, a severe allergic reaction (for example, anaphylaxis) to a vaccine component or to a prior dose is a contraindication to further doses of that vaccine. A moderate or severe acute illness is a precaution; vaccination should be deferred until the person’s condition has improved. Because MenACWY is an inactivated vaccine, it can be administered to people who are immunosuppressed as a result of disease or medications; however, response to the vaccine might be less than optimal.

A history of GBS had previously been a precaution for Menactra (MenACWY-D). Findings from two studies that examined more than 2 million doses of Menactra given since 2005 showed no evidence of an increased risk of GBS. Consequently, ACIP recommended in 2010 to remove the precaution for use of Menactra in people with a history of GBS. This precaution did not apply to other meningococcal vaccines.
