A First-Of-Its-Kind Bee Vaccine.
Dalan’s honeybee vaccine is delivered orally. The vaccine is ingested by the queen, and immunity is passed on to larvae for protection against diseases.
How it works
The Dalan vaccine technology exposes queen bees to inactive (i.e., “dead”) bacteria, which enables the larvae hatched in the hive to resist infection.
Dalan can assist in creating a custom vaccination program for your operation that is compatible with a variety of commonly used queen cages.

Why Vaccinate Your Honeybees?
Amy Franklin, MS, DVM
Contagious honey bee diseases can cause significant economic harm to the honey bee industry and devastate honey bee populations. For bacterial diseases, the use of antibiotics can result in bacterial resistance and negatively impact overall hive health. Vaccination can be a promising alternative to protect honey bee colonies and the food supply chain. Read the Article

Control of Deformed Wing Virus-B in a Commercial Apiary Following Queen Vaccination with an Experimental Paenibacillus larvae Bacterin
Dalan Animal Health
Deformed Wing Virus (DWV) is a viral disease present in the majority of honey bee colonies worldwide. There is no available treatment or preventative for DWV, therefore management of the disease is limited to indirect mite control. In a 400-hive placebo-controlled field study, we demonstrated that colonies with queens vaccinated using an experimental Paenibacillus larvae bacterin have significantly reduced DWV-B loads compared to colonies with unvaccinated queens Download Whitepaper

Frontiers in Veterinary Science
Pollination services to increase crop production are becoming more and more important, as we are facing both climate change and a growing world population. Both are predicted to impact food security worldwide. High-density, commercial beekeeping has become a key link in the food supply chain, and diseases have become a central issue in hive losses…
