Important Safety Information


Menactra vaccine is given to people 9 months through 55 years of age to help prevent invasive meningococcal disease (including meningitis) caused by serogroups A, C, Y, and W-135 of meningococcal bacteria. Menactra vaccine does not prevent serogroup B disease.

Safety Information

Side effects to Menactra vaccine include pain, redness, swelling at the injection site, headache, tiredness, and joint pain. In infants, side effects include irritability, abnormal crying, drowsiness, loss of appetite, and fever. Other side effects may occur.

Vaccination should be avoided by persons with a severe allergic reaction (eg, anaphylaxis) to any ingredient of the vaccine. Persons previously diagnosed with Guillain-Barré syndrome (GBS), severe muscle weakness, may have an increased chance of getting GBS following vaccination. Fainting can occur shortly after injecting vaccines, including Menactra vaccine. Vaccination with Menactra vaccine may not protect all individuals.
