Researchers got smart with malaria. They’ve developed a vaccine which destroys malaria in the mosquitoes which are carrying the virus. Obviously, this won’t prevent the person who gets bitten from getting malaria–but it will prevent all subsequent people getting bit from being infected. What’s ingenious about this vaccine is that it reverses the viral process itself. It operates on a community based level of prevention, rather than trying to destroy the virus per individual, which has proved essentially impossible.
This finding may pave the way for more ingenuous, community minded viral prevention.
