“There is no cure for the disease, and, until now, no vaccine to prevent it.”
Bees pollinate a third of US food crops, worth an estimated $15 billion a year, and some beekeepers are losing 70% of their colonies. The new vaccine goes into the queen’s food and protects the hive against American foulbrood. Infected hives and all their equipment get burned and buried. The vaccine covers that one bacterial disease. Parasites, pesticides and drought keep killing bees, and no vaccine fixes a pesticide.
