Coronavirus vaccines have been developed and deployed in record time, but as global rollout has progressed, too few doses have been made available in low-income countries. It’s a stark reminder that when it comes to infectious diseases, the world’s poorest often get left behind.
This is a problem that extends far beyond COVID-19. In Africa, for example, malaria has probably caused four times as many deaths as COVID-19 over the past year. Thankfully, our new research shows that an effective vaccine against malaria could now be closer than ever before.
For the first time, a vaccine has shown high efficacy in trials – preventing the disease 77% of the time among those receiving it. This is a landmark achievement. The WHO’s target efficacy for malaria vaccines is over 75%. Until now, this level has never been reached.
