The Human Anti-Crimean-Congo Hemorrhagic Fever Virus (CCHFV) IgM ELISA Kit detects and quantifies CCHFV-specific IgM in human serum or plasma of vaccinated, immunized and/or infected hosts. This immunoassay is suitable for: 1. Determining immune status relative to non-immune controls; 2. Assessing efficacy of vaccines, including dosage, adjuvantcy, route of immunization and timing; 3. Qualifying and standardizing vaccine batches and protocols.
