Summary:
- Researchers in China have developed a new technology that can turn mosquitoes into "flying vaccines" that can deliver vaccines to humans through their bites.
- The modified mosquitoes are engineered to carry vaccines in their saliva, which can then be injected into people when the mosquitoes bite.
- This innovative approach could potentially make it easier to deliver vaccines, especially in remote or hard-to-reach areas, and could be particularly useful for diseases transmitted by mosquitoes, such as malaria.
