• Researchers measured the immunogenicity of the drug by tracking antibody production in patients.
• High immunogenicity is a desirable property for an effective vaccine.
• The immunogenicity of the treatment varied among different patient groups.
• Scientists are working to improve the immunogenicity of the experimental therapy.
• The immunogenicity data showed that the vaccine triggered a strong immune response.
