The Balanced News: The First Every Honeybee Vaccine Approved By The United States is a vaccine that aims to boost the bee’s immune system so that they are able to fight against American Foulbrood disease. This disease is a bacteria-based condition that is known to attack colonies, and the honeybees are vital to our food supplies. However, because these honeybees are plagued by American Foulbrood, they have been dwindling and dying faster than expected. In fact, the numbers in which they die has been worrying. The USDA has granted a conditional license for the vaccine to be used on a limited basis by the commercial beekeepers.
