Polysaccharide Diphtheria Toxoid Conjugate Vaccine is indicated for active immunization to prevent invasive meningococcal disease caused by Neisseria meningitidis serogroups A, C, Y and W-135. This vaccine is approved for use in individuals 9 months through 55 years of age. Menactra does not prevent N meningitidis serogroup B disease.

The presence of bactericidal anti-capsular meningococcal antibodies has been associated with protection from invasive meningococcal disease. Menactra induces the production of bactericidal antibodies specific to the capsular polysaccharides of serogroups A, C, Y and W-135.

Primary Vaccination:

• Children 9 through 23 months of age: Two doses, three months apart.
• Individuals 2 through 55 years of age: A single dose.

Booster Vaccination:

• A single booster dose may be given to individuals 15 through 55 years of age at continued risk for meningococcal disease, if at least 4 years have elapsed since the prior dose.

When Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed) are to be administered to children 4 through 6 years of age, preference should be given to simultaneous administration of the 2 vaccines or administration of Menactra prior to Polysaccharide Diphtheria Toxoid Conjugate Vaccine. Administraton of Menactra one month after Polysaccharide Diphtheria Toxoid Conjugate Vaccine has been shown to reduce meningococcal antibody responses to Menactra

Pneumococcal antibody responses to some serotypes in Prevnar (PCV7) were decreased following co-administration of Menactra and PCV7.

Severe allergic reaction (eg, anaphylaxis) after a previous dose of a meningococcal capsular polysaccharide-, diphtheria toxoid- or CRM 197-containing vaccine, or to any component of Menactra

Common (≥10%): solicited adverse events in infants and toddlers 9 and 12 months of age were injection site tenderness, erythema, and swelling; irritability, abnormal crying, drowsiness, appetite loss, vomiting, and fever.

Common (≥10%): solicited adverse events in individuals 2 through 55 years of age who received a single dose were injection site pain, redness, induration, and swelling; anorexia and diarrhea. Other common solicited adverse events were irritability and drowsiness (2-10 years of age), headache, fatigue, malaise, and arthralgia (11-55 years of age).

Safety and effectiveness of Polysaccharide Diphtheria Toxoid Conjugate Vaccine have not been established in children younger than 9 months of age, pregnant women, nursing mothers, and adults older than 55 years of age.

Persons previously diagnosed with Guillain-Barre syndrome (GBS) may be at increased risk of GBS following receipt of Menactra. The decision to give Menactra should take into account the potential benefits and risks.
