(Exception: subjects with mild asthma were eligible for enrollment; subjects with moderate or severe asthma requiring routine use of inhaled or systemic corticosteroids were not eligible for enrollment);
who had epilepsy or any progressive neurological disease;
who had a history of any anaphylaxis, serious vaccine reactions, or allergy to any vaccine component;
who had a known or suspected impairment/alteration of immune function, either congenital or acquired or resulting from (for example):
receipt of immunosuppressive therapy within 30 days prior to enrollment (any systemic corticosteroid administered for more than 5 days, or in a daily dose \>1 mg/kg/day prednisone or equivalent during any of 30 days prior to enrollment, or cancer chemotherapy);
receipt of immunostimulants;
receipt of parenteral immunoglobulin preparation, blood products, and/or plasma derivatives within 90 days prior to enrollment and for the full length of the study;
common childhood exanthematous diseases (varicella, mumps, measles, rubella) occurring 6 weeks prior to vaccination;
who were known to have a bleeding diathesis or any condition that could be associated with a prolonged bleeding time;
who had Down syndrome or other known cytogenic disorders;
whose families were planning to leave the area of the study site before the end of the study period;
who had any condition that, in the opinion of the investigator, could interfere with the evaluation of the study objectives.

Intervenciones

biological

Meningococcal ACWY-CRM conjugate vaccine

MenACWY-CRM vaccine was obtained by extemporaneous mixing of the lyophilized MenA component to be resuspended with the liquid MenCWY component. One dose (0.5 mL) was administered by IM injection in the deltoid area of the arm without a BCG scar.

biological

Meningococcal ACWY-PS polysaccharide vaccine

MenACWY-PS vaccine was supplied as a single dose (one vial of vaccine and one vial of diluent). One dose (0.5 mL) of MenACWY-PS vaccine was administered by SC injection in the deltoid area of the arm without a BCG scar.

A Phase 3, Randomized, Observer-blind, Controlled, Multi-Center Study to Compare the Safety of One Dose of Novartis Meningococcal ACWY Conjugate Vaccine With That of a Licensed Meningococcal ACWY Polysaccharide Vaccine (Menomune®) Administered to Healthy Children 2 to 10 Years of Age
