About MenQuadfi

MenQuadfi should not be administered to anyone who has had a severe allergic reaction to any component of the vaccine, or after a previous dose of MenQuadfi or any other tetanus toxoid-containing vaccine.

Appropriate medical treatment must be immediately available to manage potential anaphylactic reactions following administration of MenQuadfi.

Some individuals with altered immunocompetence, including some receiving immunosuppressant therapy, may have reduced immune responses to MenQuadfi. Persons with certain complement deficiencies and those receiving treatment that inhibits terminal complement activation (eg, eculizumab) are at increased risk for invasive disease caused by N meningitidis, including serogroups A, C, W, and Y, even if they develop antibodies following vaccination with MenQuadfi.

Syncope (fainting) may occur in association with administration of injectable vaccines, including MenQuadfi. Procedures should be in place to avoid injury from fainting.

Guillain-Barré syndrome (GBS) has been reported in temporal relationship following administration of another US-licensed meningococcal quadrivalent polysaccharide conjugate vaccine. The decision to give MenQuadfi to persons with a history of GBS should take into account the expected benefits and potential risks.

Immunization with MenQuadfi does not substitute for routine tetanus immunization.

Vaccination with MenQuadfi may not protect all vaccine recipients.

The most common adverse reactions following primary vaccination with MenQuadfi in infants 6 weeks through 23 months of age include tenderness, erythema, and swelling at the injection site; irritability, abnormal crying, drowsiness, appetite loss, fever, and vomiting. In individuals 2 years of age and older, the most common adverse reactions include pain at the injection site; myalgia, headache, and malaise. Other common adverse reactions in children 2 through 9 years of age include erythema and swelling at the injection site. In adolescents and adults, rates of solicited adverse reactions following a booster dose were comparable to those observed following primary vaccination. Other adverse reactions may occur.
