Colony Loss Relief Special Offer
Protect against losses with Dalan’s vaccine and get $500+ back
Protect and invest in your hive health.
Dalan and The Bee Expo are committed to putting beekeepers and bees first. With alarming hive losses reported this year, we recognize the urgent need for both colony health and financial support for beekeepers. That’s why we’re partnering with major beekeeping retailers to offer a minimum $500 gift card when you purchase Dalan’s honeybee vaccine—helping you protect your colonies from disease and invest back into your operation.
How It Works
The Dalan vaccine 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

Frequently Asked Questions
The vaccine works through Transgenerational Immune Priming (TGIP), whereby the maternal insect passes immunity to her offspring. The vaccine, containing a killed pathogen, is administered orally to queen bee via workers. As she ingests it, pieces of the vaccine are transported to her ovaries where it is deposited in the eggs. The developing larvae are exposed to the vaccine and start to build up immunity before they hatch.
One vial of the vaccine is thoroughly mixed with 300g of queen candy. 6g of candy is placed in a queen cage containing 6-10 attendants and a mated queen. The cage is kept in a cool dark space with proper water exposure for 7 days while the attendants feed the queen. On day 8, the queen can be released into a hive or be placed in a queen bank.

The vaccine is conditionally licensed by the USDA and CFIA to prime larvae against mortality from Paenibacillus larvae. This bacteria is the causative agent of American Foulbrood Disease (AFB), a highly contagious and devastating disease that destroys the developing bee larvae.
Learn more about new experimental data showing how vaccination significantly reduced DWV-B in a large commercial yard in American Bee Journal.
No, the vaccine does not contain mRNA technology. The vaccine contains inactivated (dead) Paenibacillus larvae bacteria, the causative agent of American Foulbrood Disease. The vaccine does not contain any chemicals or harmful preservatives and is suitable for use in organic agriculture.
More information on the vaccine’s properties can be found in the package insert.
The USDA and CFIA have approved the vaccine for use and reviewed Dalan’s data indicating that the vaccine is safe. After over 5 years of study using thousands of doses of vaccine, immune priming has never indicated a negative impact on queen fitness or honey composition.

Yes, the vaccine is suitable for use in organic agriculture. It is non-GMO and does not containany chemicals or harmful preservatives.
The immunity is passed onto the queen’s offspring, but a new queen born from the hive will not be able to pass this immunity onto her offspring. The immunity lasts one generation. New queens born from the hive would need to be replaced with a vaccinated queen or removed from the hive to be vaccinated.
The vaccine does not kill the bacterium. Our AFB vaccine utilizes a dead bacterium to promote an immune response within the honeybee. Vaccination of the queen bee has been shown to limit disease by passing on immunity and/or stimulating immunity in newly hatched larvae (Transgenerational Immune Priming or TGIP).
No. This has not been assessed. We recommend vaccinating a fresh queen for 8 days outside of the hive, making sure her attendants have access only to the vaccinated candy. Removing a queen from the hive, vaccinating her for 8 days, and returning her to the hive is not recommended.
The immunity lasts one generation. We recommend requeening annually with vaccinated queens.
