Virus vaccines
Abstract
Improved mammalian virus vaccines are combinations that contain an immunogenic amount of inactivated virus, such as influenza virus, Herpes varicella virus, measles virus, Epstein Barr virus, respiratory syncytial virus, parainfluenza 3, Herpes simplex type 1 virus, and Herpes simplex type 2 virus, and an immunogenic amount of a purified recombinant envelope protein from the virus, or a fragment or precursor of the protein. Alternatively, they contain either inactivated virus and/or envelope protein antigens and an adjuvant such as granulocyte-microphage colony stimulating factor. One embodiment of an influenza vaccine is prepared by combining inactivated virus, preferably three strains of the virus, and hemagglutinin, preferably a combination of respective hemagglutinins for each of the three strains present. In another embodiment, an influenza vaccine is prepared by combining inactivated virus, again preferably three strains of the virus, and neuraminidase, preferably a combination of respective neuraminidase for each of the three strains present. In a third embodiment, the vaccine contains inactivated virus and both hemagglutinin and neuraminidase, preferably using three strains of each. Granulocyte-macrophage colony stimulating factor is, optionally, added to these embodiments.
