Malaria vaccine?

Published May 22, 2020

Two new trials show we’re getting closer to a malaria vaccine. The interesting thing about these candidates (beyond the fact that a vaccine could save 400,000 people a year) is that they’re made by genetically modifying some of the parasites that cause malaria.

Downside: The trials showed these vaccines were safe, but one was only about 40 percent effective, and the other doesn’t lend itself to being scaled up very well. But both are still a step closer to saving a heck of a lot of people.

 Speaking of malaria…

One of the most common tools against malaria is the simple bednet — a screen around the bed that keeps mosquitoes out.

So what are the little bastards doing? Evolving to bite people earlier in the day, before the bednets are up.
