Abstract

Objective To explore the stability of freeze-dried groups A and C meningococcal polysaccharide conjugate vaccine at 2-8℃.Methods Store freeze-dried groups A and C meningococcal polysaccharide conjugate vaccine at 2-8℃ for 30 months.Take samples periodically for inspection of final containers,identity test,abnormal toxicity test,immunogenicity test as well as determination of polysaccharide content,moisture content and molecular size to evaluate the stability of vaccine.Results All the quality control indexes of freeze-dried groups A and c meningococcal polysaccharide conjugate vaccine after storage at 2-8℃ for 30 months met the requirements for product license.Conclusion Freeze-dried groups A and C meningococcal polysaccharide conjugate vaccine showed good stability at 2-8℃.
