Methods Activate groups A and C meningococcal polysaccharide with cyanogens bromide and prepare into MenAPS-ADH and MenCPS-ADH derivatives by reacting with 1, 6-adipic acid dihydrazine. Mix MenAPS-ADH and MenCPS-ADH derivatives with purified tetanus toxoid at a certain mass ratio, then add l-ethyl-3(3-dimethylaminopropyl)-carbodiimide to prepare bulks of MenAPS-TT and MenCPS-TT conjugates respectively. Mix the two bulks at a certain ratio, add stabilizer and lyophilize to prepare group A+C meningococcal polysaccharide conjugate vaccine.
