Appropriate medical treatment & supervision should be available in case of rare anaphylactic event following vaccination. Do not administer intravascularly, intradermally or SC. Review patient's medical history (especially previous vaccination) & clinical exam. Postpone vaccination in patients w/ acute severe febrile illness. Syncope can occur following or before any vaccination; place procedures to avoid injury from faints. Individuals w/ thrombocytopenia or any coagulation disorder. Increased risk for invasive disease caused by
Neisseria meningitidis groups
A, C, W-135 & Y in persons w/ certain complement deficiencies & those receiving treatment that inhibits terminal complement activation (eg, eculizumab) even if they develop Ab following vaccination w/ Nimenrix. Patients receiving immunosuppressive treatment or those w/ immunodeficiency may not elicit an adequate immune response. Individuals w/ increased susceptibility to meningococcal infection due to anatomic/functional asplenia (eg, sickle cell disease). No protection against other
Neisseria meningitidis groups. Protective immune response may not be elicited in all vaccinees. Consider booster dose if an individual is expected to be at particular risk of exposure to group A & has previously received a dose approx >1 yr; individuals remaining at high risk of exposure to meningococcal disease caused by groups A, C, W-135 & Y. Not a substitute for tetanus immunisation. Pregnancy & lactation. Consider 2nd primary dose after 2-mth interval if infant (6 to <12 mth) or toddler is expected to be at immediate risk of invasive meningococcal disease due to exposure to groups W-135 &/or Y.
