US health officials warn dairy workers of bird flu risk from cows, advise to wear protective gear

The bird flu virus has been found in one out of five samples of milk in grocery stores in the United States. There is growing talk about a mass vaccination campaign to inoculate people against a possible bird flu pandemic. Massive amounts of H5N1 vaccines would be needed if the World Health Organization declares a global bird flu pandemic. Barron’s Magazine is reporting that the US government has vaccines in stock for one-fifth of the American population.
