Why aren’t we vaccinating birds against bird flu?

“Even with biological, technological, and logistical hurdles surpassed, the decision around vaccination seems to be a monetary one. Beyond the cost of vaccination, there’s the potential of losing key trade partners. Trade agreements, especially for meat, are notoriously delicate, in part because of the risk of introducing infectious diseases and pests into a country’s food chain but more so because governments need to protect the agricultural industry from foreign competition. The National Chicken Council is opposed to vaccination efforts. The National Turkey Federation says unilateral vaccination “would have a severe impact on exports” but that it has urged — and continues to urge — the federal government to “move as rapidly as possible to try to develop new agreements” with trading partners.
“Meat is a highly politically sensitive issue for many countries, and the entire livestock industry is protected in many countries for various reasons,” said Aratchilage. Introducing bird flu vaccines is not going to be easy, he added. “It’s a political decision more than a scientific decision.””
