| Avonex ® contains albumin, a derivative of human blood.
Based on effective donor screening and product manufacturing processes,
it carries an extremely remote risk for transmission of viral and prion
diseases.
A theoretical risk exists therefore, for transmission of Creutzfeldt-Jakob
disease (CJD) although this risk is considered extremely remote.
No cases of transmission of viral (prion) diseases or CJD have been
identified for albumin.
