Of Risk and Gene Drives

A few weeks ago, I attended a panel on gene editing at Harvard Medical School that covered some aspects of the science, ethics, and law of the practice. It was an interesting talk, in part because it largely covered the ethical issues of gene editing for human medicine and in other species as two sides of the same coin, rather than as fundamentally different conversations, as they are often treated.

Indeed, one member of the audience asked why there is so much focus on the safety and ethics of human gene editing, when the stakes, he argued, are much higher in the use of gene editing for environmental engineering. A botched human germline edit could harm a family; a botched gene drive could kill us all. It’s an interesting point. And because it suggests that we may want to be less than sanguine on the use of gene drives to eradicate malaria, on which I have previously been extremely sanguine, it is a point worth responding to.

Malaria Eradication: For Africa as America

There is a page in the history books waiting to be written for the eradication of malaria. In recent years, malaria has killed more people globally than war—it’s killed predominately children, and predominately in sub-Saharan Africa. Despite being curable, and eliminated from most developed countries, malaria is the fifth deadliest infectious disease in the world.

A team of scientists in Italy is looking to write that history. Read More
