Could a rogue scientist use CRISPR to conjure another pandemic?

As a television writer and producer of “ER,” “SVU,” and most recently “Designated Survivor,” I draw on audiences’ love-hate relationship with uncertainty to play on their emotions. I know that audiences love plots riven with unexpected twists and turns.

When we’ve emerged on the other side of the pandemic, Covid-19 will someday make a good story. But I worry that CRISPR could make Covid-19 look like child’s play.

CRISPR is a new genetic tool that lets scientists cut out a DNA sequence in an organism’s genome and replace it with another. The hope is that this ingenious scissors-and-glue system will be used to treat devastating genetic diseases like sickle cell anemia and beta thalassemia.

But there’s a dark side to CRISPR. A scientist or biohacker with basic lab know-how could conceivably buy DNA sequences and, using CRISPR, edit them to make an even more panic-inducing bacteria or virus. What’s to stop a rogue scientist from using CRISPR to conjure up an even deadlier version of Ebola or a more transmissible SARS?
