AlphaVax, Inc. Announces Results from Initial Testing of Its H1N1 (Swine) Influenza Vaccine


7/19/2009 10:49:26 PM

RESEARCH TRIANGLE PARK, N.C., July 17 /PRNewswire/ -- AlphaVax, Inc. announced today that it has completed process development and preclinical immunogenicity studies of its H1N1 (swine) influenza vaccine and will manufacture clinical trial material by the end of the month. This vaccine has shown good production yields as well as excellent immunogenicity, even after just a single inoculation.

The studies performed at AlphaVax utilized the California 04/2009 HA sequence obtained from the WHO GISAID database on April 25th. Mice inoculated with the AlphaVax H1N1 vaccine showed strong dose-dependent hemagglutination inhibition ("HI") antibody responses. After just a single dose of the H1N1 vaccine, all vaccinated animals developed HI antibody levels considered to be protective. These responses were boosted approximately 8-fold by a second dose given three weeks later. Responses measured by ELISA and ELISPOT assays, which assess antibody and T cell responses, respectively, mirrored the HI responses. The design of future clinical trials of this vaccine will be based on two previous successful influenza vaccine trials run by AlphaVax, one carried out in healthy young adults and the other in an elderly population.
