Agriculture officers in America are testing four vaccines which they hope will stop the latest outbreak of a highly pathogenic avian influenza that has devastated poultry farms and driven up egg prices. The Government plans to launch a national vaccination campaign.
Two of the vaccines being tested were developed by the U.S. Department of Agriculture. The others are from animal drugmaker Zoetis and Merck Animal Health, which were developed in 2015 but not used. It will take up to two years before commercial quantities of vaccine are available to match the currently circulating virus s, H5N1. In the US alone, almost 60 million farm-raised birds have died or been killed to stop the spread.
