The World's First
Approved Bee Vaccine

Dalan’s platform technology is delivered orally. The vaccine is ingested by the Queen Bee, and vaccine fragments are 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.

  • (1) The vaccine is mixed with queen candy.

  • (2) Worker bees consume the vaccine with the queen candy which is then digested and transferred to the glands that produce the royal jelly.

  • (3) Worker bees feed the royal jelly containing the vaccine to the queen.

  • (4) The queen digests the royal jelly and the vaccine is transferred to her ovaries. She is then released into the hive.

    (5) The vaccine is transferred to the developing eggs.

    (6) The developing larvae (now vaccinated) are more immune to infection as they hatch.

Dalan Animal Health is using its platform technology to develop vaccines for multiple diseases.

Proven Safety

Queen survival. In tests, immune priming showed no negative impact on queen fitness.

Proven Safety

Honey quality. Our tests also show no negative impact on honey. Our product is chemical free, non-GMO, and organic.

Our vaccine is conditionally licensed by the USDA-CVB and CFIA-CCVB for the vaccination of queen honeybees to prime larvae against mortality due to Paenibacillus larvae.

In field trials conducted across the U.S, we have correlated a decrease in viral pathogens such as Deformed Wing Virus (DWV) with vaccinated colonies.

“What this team is accomplishing will be
the long term future of beekeeping. It’s the change and the direction that the industry has badly needed for some time and has patiently waited for.”
