For 40 years, Dr. Timothy Lepore has treated numerous Lyme disease patients on Nantucket Island, where 15% of residents are affected. Scientists aim to curb Lyme transmission by genetically engineering Lyme-resistant mice and releasing them on the island. The project targets wild mice, the main Lyme bacteria host, rather than deer or ticks. While promising, concerns exist about ecological impacts. Extensive community engagement and small-scale trials are planned before any release on Nantucket.
