Prazo: One month post-vaccination (At Month 1)
Vaccine response induced by Neisseria meningitidis serogroups A, C, W-135 and Y (MenA, MenC, MenW-135 and menY) as measured by serum bactericidal antibodies using baby rabbit complement (rSBA), was defined as an rSBA titer of at least 1:32 in subjects initially seronegative [rSBA titer below (<) 1:8] and as a 4-fold increase in titer in subjects initially seropositive [rSBA titer greater than or equal to (≥) 1:8].
One month post-vaccination (At Month 1)
Number of Subjects With Any Grade 3 General (Solicited and Unsolicited) Symptoms
Prazo: During the 4-day (Days 0-3) period after vaccination
General symptoms assessed included fatigue, fever (defined as axillary temperature), gastrointestinal symptoms and headache. Grade 3 symptom= event that prevented normal activities. Grade 3 fever= temperature above (>) 39.5 degrees Celsius (°C).
During the 4-day (Days 0-3) period after vaccination
