Ecological vaccination: A strategy to prevent zoonotic spillover from bats Harnessing natural behaviors to vaccinate wild bats reduces zoonotic spillover risk while supporting conservation.

This is a fascinating study!
Researchers developed an incredible new approach to prevent pandemic spillovers by vaccinating BATS themselves using mosquitoes and salt traps. It comes with some risk and caveats and will need robust regulation for prime time.🧵
