The World’s First Bee Vaccine Received Conditional License by USDA

BeesDomesticated honeybees play a vital role in the economy by pollinating many agricultural plants. However, a variety of negative factors have led to a 90% decline in their population since 1962. But scientists report a possible breakthrough in the conservation and recovery of bee populations.The US Department of Agriculture has approved PrimeBEE, a vaccine that protects honeybees from American Foulbrood disease – a bacterial infection that kills larvae. This product from Dalan Animal Health is the first bee vaccine of its kind.

"This is an exciting step forward for beekeepers, as we rely on antibiotic treatment that has limited effectiveness and requires lots of time and energy to apply to our hives," Trevor Tauzer, board member of the California State Beekeepers Association, explained. "If we can prevent an infection…, we can avoid costly treatments and focus our energy on… keeping our bees healthy."

For the vaccine to work, it must be mixed with royal jelly and then workers feed it to the queen bee. The vaccine particles will penetrate into the ovaries of the queen and from there into the yolk of the eggs. Her offspring will gain innate immunity to blight. According to experts, the use of the drug can significantly reduce bee mortality from this infection and slow down its spread.American Foulbrood infection originated in the United States and has spread around the world, with up to a quarter of hives infected in some regions. These microorganisms infect and kill young bee larvae within the first three days of their life, turning their bodies into a brownish slime. Some success in treatment can be achieved with specific antibiotics, but because the bacterial spores remain viable for several decades, regulatory agencies require the complete destruction of bees in infected families and the burning of their hives.

"We are committed to providing innovative solutions to protect our pollinators and promote sustainable agriculture… Our vaccine is a breakthrough in protecting honeybees. We are ready to change how we care for insects, impacting food production on a global scale," Dr. Annette Kleiser, CEO of Dalan Animal Heal, said.

Thanks to the license, the company will be able to supply a limited amount of vaccine to US beekeepers over the next two years. If the results are positive, the restrictions will be lifted. Experts also note that if successful, the vaccine could serve as the basis for drugs for other similar diseases, particularly European blight. In addition, the company is already thinking about creating vaccines for other commercial arthropods, such as mealworms and shrimp.
