Last year, scientists at a company called Dalan Animal Health created a new vaccine. It protects bees from the disease.
But how can you give a vaccine to the world’s billions of bees? It’s impossible to feed it to the thousands of bees in just one hive. Scientists needed another way.
They knew that some animals can pass immunity to diseases from mothers to their babies. Would that be true for bees? If so, scientists would just have to vaccinate the hive’s queen bee. One queen can lay up to two thousand bees every day.
After many failed experiments, the scientists thought of a way to vaccinate the queen. They know that worker bees feed the queen. So they fed the vaccine to a few worker bees, which fed it to the queen bee. After the queen ate it, her babies didn’t get sick. The vaccine worked!
