One way this could work, Qi says, is by delivering PAC-MAN treatments through a nasal spray or some other form of nebulizer. “My son has asthma,” he says, “so as a little kid playing football he used a nebulizer as a preventive measure. People use these regularly to prepare the lung to be less allergic if they are exposed to something.” The same could be done during a coronavirus pandemic; people could use a nasal spray so that PAC-MAN or another CRISPR-Cas13 prophylactic treatment will protect them.
