Researchers are pioneering vaccination for invertebrates, with honeybees and shrimp receiving vaccines to combat diseases. The honeybee vaccine, approved by the U.S. Department of Agriculture, enhances resistance to pathogens, while a potential shrimp vaccine shows significant survival rates against specific bacteria and viruses. These advancements could transform agricultural practices and reduce antibiotic use.
- 01The honeybee vaccine, made from inactivated Paenibacillus larvae, enhances resistance to American foulbrood disease.
- 02Vaccinated shrimp showed increased survival rates from 27% to 48% against Vibrio parahaemolyticus and from 0% to 58% against white spot syndrome virus.
- 03Dalan Animal Health is conducting field trials in Southeast Asia to gather efficacy data for the shrimp vaccine.
- 04The vaccines leverage innate immunity and epigenetic changes to create immune memory in invertebrates.
- 05Other invertebrate species, such as silkworms, may also benefit from vaccination against specific pathogens.

In a groundbreaking development, researchers are now vaccinating invertebrates, with honeybees and shrimp at the forefront. The U.S. Department of Agriculture has conditionally approved a honeybee vaccine that protects against American foulbrood, a disease caused by the pathogen Paenibacillus larvae. This vaccine is administered to the queen bee, resulting in her offspring inheriting increased resistance to the disease. Meanwhile, a potential shrimp vaccine has demonstrated promising results in laboratory trials, significantly increasing survival rates against harmful pathogens such as Vibrio parahaemolyticus and white spot syndrome virus. The shrimp vaccine is designed to be fed to brood stock, allowing the immunity to be passed onto the next generation. These advancements could revolutionize agricultural practices, reducing reliance on antibiotics and addressing the substantial economic losses caused by diseases in both honeybee and shrimp populations, valued in the billions. Dalan Animal Health is preparing for field trials in Indonesia to further validate the shrimp vaccine's efficacy.
