For the first time, vaccines are being applied to invertebrates such as bees and shrimp to combat diseases that decimate colonies and hatcheries. Immunization is administered to queens or breeders, transmitting protection to offspring. This breakthrough reduces the massive use of antibiotics and prevents million-dollar losses in key sectors such as agriculture and aquaculture.
The mechanism: how an insect’s immune system is trained 🧬
The technology is based on inactive fragments of the pathogen that, when ingested by the queen or breeder, activate primitive but effective defense mechanisms. In bees, the vaccine is mixed with royal jelly; in shrimp, it is incorporated into the feed. Protection is transferred to offspring through specific proteins in the eggs. This allows raising entire resistant batches without resorting to antibiotics, curbing outbreaks such as American foulbrood or white spot syndrome virus.
The revolution of the vaccinated: now even bugs have a vaccination card 🐝
While humans debate whether to get the fourth dose, bees already have their own vaccination schedule. Of course, no one has asked them if they prefer the syringe brand or a bit of syrup. The good thing is that, unlike certain forums, they don’t debate whether the vaccine has a microchip or not; they simply eat it and that’s that. Fewer antibiotics in the field and more honey on the table. Although the shrimp, discreetly, still have no opinion.
