New vaccine may give long-term defense against deadly bird flu and its variant forms

Dr. Mittal Bird Flu

A new vaccine that apparently can provide long-lasting protection for pathogenic bird flu, H5N1, and its mutations, has been developed by Purdue researchers in collaboration with the Centers for Disease Control and Prevention. Purdue virologist Suresh Mittal said that compared to traditional vaccines, the new vaccine would have the advantages of not being based on eggs, would be easy and fast to produce, and could easily be modified to changes in the flu virus.

WEST LAFAYETTE, Ind. - A new vaccine under development may provide protection against highly pathogenic bird flu and its evolving forms, according to researchers at Purdue University and the Centers for Disease Control and Prevention who discovered the new preventative drug and have tested it in mice.

Unlike traditional influenza vaccines, the new vaccine could be produced quickly and stored for long periods in preparation for a pandemic of dangerous disease-causing avian influenza - H5N1 - and its variants, said Suresh Mittal, a Purdue virologist. In an earlier study with mice, he and his colleagues found that the vaccine protected against H5N1 for a year or longer. Because the studies have only been done in mice, it's not yet known whether the same results will be obtained in humans."
