Malaria kills a very high number of African children every year. But there’s hope now: malaria vaccines. According to the World Health Organization, new evidence shows that in the first countries using the vaccine, about 1 in 8 child deaths were prevented among kids eligible to get it. WHO also said that about 438,000 African children died from malaria in 2024, and that thousands of lives could be saved each year with more widespread vaccine rollout.

This basically summarizes everything I really care about. It’s prevention, it’s global health, and it’s about reaching the kids who need it most. Seeing how malaria affects communities like the one in Nigeria up close made this real for me, and not just a statistic.

But the same theme keeps coming back: the vaccine only helps if children can actually get to it, and WHO points out there are still funding challenges to make it available to everyone. It’s the same lesson as the polio story I shared earlier. We can invent amazing tools, but the problem isn’t really solved until they get to the right people. That’s the part I want to be able to work on wen I graduate from college.
