Summary:

- Chinese scientists have developed a novel way to vaccinate bats against diseases by using mosquitoes as a delivery system. They have genetically modified mosquitoes to carry a vaccine that can be transmitted to bats when the mosquitoes feed on them.

- This approach is particularly useful for vaccinating bats, which are difficult to capture and handle directly. By using mosquitoes as a "living vaccine delivery system," the researchers can effectively immunize bat populations against diseases like rabies without the need for direct contact.

- The successful development of this mosquito-based vaccination method could have important implications for public health, as bats are known to harbor many viruses that can potentially spill over to humans. Controlling diseases in bat populations could help prevent future zoonotic outbreaks.
