      1. Local erythema (11% for IM, 32% for SC)
      2. Headache (3% for IM and 12% for SC)
    2. Intramuscular has same efficacy as Subcutaneous Route

V. Efficacy

  1. Like Menactra, Menomune has a high seroconversion rate (98%-100%)
  2. However Menomune duration is much shorter
    1. Menomune duration lasts 3 years in school age children and less in infants

VI. Precautions: Safety

  1. No longer contains Thimerosal
  2. Approved for all ages
  3. Safe in Human Immunodeficiency Virus (HIV)
    1. See Immunization in HIV

VII. Adverse effects
