1. Ongoing research in hCG birth control vaccines has focused on improving immunogenicity . 2. O-acetylated polysaccharides influence the immunogenicity of meningococcal vaccines. 3. Mutated genes contribute greatly to the immunogenicity of human tumors. 4. Multiple factors affect immunogenicity of DNA plasmid HIV vaccines in human clinical trials. 5. The reason for the low immunogenicity of the peptide is not well understood. 6. Human IgG allotype is one of the many factors that can contribute to immunogenicity . 7. However, problems were encountered due to low efficacy, reactogenicity and low immunogenicity . 8. Various vaccines have reached the state of clinical trials; most demonstrated insufficient immunogenicity . 9. This study found that the immunogenicity of OncoVAX was unaffected by the manufacturing process. 10. The immunogenicity of xenogeneic tissues may be different from and even stronger than allogeneic tissues.
