Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them.

Input:Safety and immunogenicity of a tetravalent meningococcal serogroups A, C, W-135 and Y conjugate vaccine in adolescents and adults.  The highest incidence of invasive meningococcal disease is in young children, with a second peak in adolescents/young adults. All five major disease-causing serogroups (A, B, C, W-135 and Y) have been described in Asia. Immunogenicity and safety of the investigational meningococcal ACWY-tetanus toxoid conjugate vaccine (ACWY-TT, GlaxoSmithKline Biologicals) was evaluated in healthy, meningococcal conjugate vaccine-naïve adolescents in the Philippines, India and Taiwan. 1025 adolescents were randomized (3:1) to receive one dose of ACWY-TT or tetravalent ACWY polysaccharide vaccine (Mencevax™, Men-PS). Serum bactericidal activity using rabbit complement (rSBA) was measured. Local and systemic adverse reactions were recorded for 4 days. Safety data were pooled with results from a second, similarly designed study in adults for evaluation of grade 3 systemic events. The pre-specified immunogenicity criterion for non-inferiority to Men-PS was met. One month post-vaccination, ≥85.4%-97.1% had a vaccine response (post-titre ≥1:8 in initially seronegative and ≥4-fold increase in seropositive), versus 78.0%-96.6% after Men-PS, against each vaccine serogroup. Exploratory comparisons showed statistically significantly higher post-vaccination rSBA geometric mean titres against all serogroups following ACWY-TT versus Men-PS. Exploratory analysis showed no statistically significant differences between groups in grade 3 general symptoms; however, the statistical criterion for non-inferiority between pooled treatment groups in terms of the ratio of incidences of grade 3 general symptoms was not demonstrated. No SAEs were related to vaccination. ACWY-TT was immunogenic in Asian adolescents with a reactogenicity profile that was clinically acceptable and similar to that of licensed Men-PS. The results of this study indicate that ACWY-TT could be used as a third conjugate vaccine in the protection of adolescents against meningococcal disease. Output:
