In recognition of World Malaria Day, Lab Land will have a series ofÂ posts from Taryn McLaughlin, a graduate student in Emoryâ€™s IMP program. Her posts will set the stage for upcoming news about malaria research at Emory and Yerkes. Taryn is part of Cheryl Dayâ€™s lab and is also an associate producer with theÂ AudiSci podcast.
Those of us in the US are fortunate to not have to consider malaria in our day-to-day lives. Globally though, malaria is a serious public health threat with nearly 3.2 billion people at risk and close to half a million deaths every year. The scientific community has been developing malaria vaccines for decades. Yet a robust vaccine still remains elusive. Why?
One set of barriers comes from economics:Â malariaâ€™s strongest impact is in developing countries. But there is just as strong a case to be made for scientific obstacles. Frankly, the parasite (technically a bunch of species of microbes that I’ll just lump together under the umbrella term Plasmodium) that causes malaria is just smarter than we are.
I’m only kidding, but it is a fascinating organism. Its complexity makes it difficult to pin down and also interesting to write about. But before we talk about why Plasmodium is such a pain, let’s first discuss what exactly makes an effective vaccine. Read more
