Original Note:
In 1981, MPSV4 (Menomune) was licensed. Immunogenicity was compared with A/C meningococcal polysaccharide vaccine. It is unethical to withhold effective treatments if available from trial participants; therefore new vaccines are compared to older as placebo https://www.cdc.gov/mmwr/preview/mmwrhtml/rr5407a1.htm https://www.nia.nih.gov/health/clinical-research-benefits-risks-and-safety
