Immune Lot Consistency, Immunogenicity, and Safety of an Investigational Quadrivalent Meningococcal Conjugate Vaccine

Healthy meningococcal-vaccine naïve adolescents and adults were randomized and received a single dose of either MenACYW Conjugate vaccine from 1 of the 3 lots (Lot 1, Lot 2, or Lot 3) or Menactra®. They were assessed for immunogenicity at baseline (pre-vaccination) and at 30 to 44 days post-vaccination. Safety information were collected post-vaccination and throughout the entire study.
