Trial with three vaccines against bird flu

Wageningen Bioveterinary Research (WBVR) has started a trial with bird flu vaccination. In Lelystad vaccines against bird flu of three different pharmaceutical companies are tested. In the trial vaccines against the current H5 viruses are tested in laying hens. "More information about the potential vaccines against bird flu is required before these can be applied in the field," explains bird flu researcher Nancy Beerens. The research is done under commission of the Dutch ministry of Agriculture, Nature and Food Quality. This first vaccine trial is performed in the animal facilities in the high containment unit of WBVR. The modern vaccines were developed by three different pharmaceutical companies; the tested vaccines are based on different technologies.
