Zusammenfassung:The fusion (F) protein, attachment (G) protein and matrix (M) protein of respiratory syncytial virus (RSV) are isolated and purified from respiratory syncytial virus by mild detergent extraction of the proteins from concentrat ed virus, loading the protein onto a hydroxyapatide or other ion-exchange matri x column and eluting the protein using mild salt treatment. The F, G and M proteins, formulated as immunogenic compositions, are safe and highly immunogenic and protect relevant animal models against disease caused by respiratory syncytial virus infection.
