GoKawiilStripe previously organized a $1.8 billion program called Frontier to encourage the development of carbon removal technology, as a way of countering climate change. Ransohoff says removing carbon from the atmosphere and getting rid of respiratory viruses are similar in that each is “technically possible” but they “lack commercial incentives.”
The concept for Intercept took shape after Ransohoff started talking to David Veesler, a structural biologist and vaccine designer at the University of Washington, who argued that it’s possible to come up with broad countermeasures that work against many viruses at once.
“He effectively sort of nerd-sniped me,” Ransohoff says of Vessler. “He convinced me that this is technically possible. He also helped me understand that some of the reasons that this hasn't been done before was sort of an incentive problem.”
Veesler says the growing toolkit available to scientists includes RNA drugs, antibodies, and computational protein design. For instance, one idea is to engineer virus-grabbing proteins that people could spray in their nasal passages, to catch viruses before they can infect people.
“Most people just accept these viruses as a fact of life, and that got us thinking: do we have to accept it?” says Veesler. “The more we thought about it, the more we realized that many of these problems have not been worked on with modern technologies.”
