Solicited AEs for 7 days following vaccination
Unsolicited adverse events
Unsolicited AEs for 28 days following vaccination
Serious adverse events (SAEs)
SAEs for 6 months following vaccination

5. Study Description
Brief Summary
This observer-blind, randomized, active controlled trial will be conducted among 2-29 year olds in two sites (Mali and The Gambia). The objectives of the study are to assess and compare the immunogenicity and safety of NmCV-5 with that of Menactra.
A total of 1800 eligible participants (who or their parents/guardians have given written informed consent) will be randomised 2:1 (NmCV-5: Menactra) in each of the three age strata 18-29 years, 11-17 years & 2-10 years (400 NmCV-5 recipients & 200 Menactra recipients in each age strata).
Each subject will receive a single dose of study vaccine and will be followed up for 6 months post vaccination during which solicited reactions (for seven days), unsolicited AEs (28 days) and SAEs (until the end of study i.e. 168 days after vaccination) will be collected. A blood sample will be collected at baseline (pre-vaccination) and at day 28 post-vaccination for immunogenicity assessment by a Serum Bactericidal Activity assay using rabbit complement (rSBA).
