The vaccine targets a disease known to weaken colonies by attacking bee larvae.
It was engineered to prevent fatalities from American foulbrood disease, a bacterial condition known to weaken colonies by attacking bee larvae.
It works by introducing an inactive version of the bacteria into the royal jelly fed to the queen, whose larvae then gain immunity.The USDA says many, sometimes overlapping, factors threaten honey bee health, including parasites, pests and disease, as well as a phenomenon called Colony Collapse Disorder, which occurs when worker bees abandon a hive and leave behind the queen.
The new vaccine contains an inactive version of the bacteria that causes American foulbrood disease, Paenibacillus larvae, according to Dalan Animal health. It says this gives bee larvae immunity to the disease as they hatch and reduces death from the illness.
