Giving long-lasting Lyme protection to wild white-footed mice

Heritable immunization of the white-footed mouse reservoir of Lyme disease

NIH-funded research Massachusetts Institute of Technology · NIH-11172237

Researchers aim to create a one-time genetic immunization for white-footed mice to cut the number of infected ticks and lower Lyme disease risk for people.

What this research studies

This project plans to genetically encode protective antibodies against Borrelia burgdorferi into the germline of white-footed mice so that offspring inherit Lyme protection. The team will combine multiple antibodies targeting the bacteria's outer surface protein A (OspA) to reduce the chance the bacteria can evolve around the protection. Work will include laboratory genetic engineering and controlled field studies tracking infection rates in mice and ticks. The goal is that fewer infected ticks will mean fewer opportunities for people to get Lyme disease over many years.

Who could benefit from this research

Good fit: People who live, work, or spend time in Lyme-endemic regions—especially in areas with many ticks—would be most likely to benefit.

Not a fit: People who live outside areas with white-footed mice or where Lyme is rare, or whose symptoms are from other causes, are unlikely to see direct benefit.

Why it matters

Potential benefit: If successful, the approach could durably lower the number of infected ticks and reduce human cases of Lyme disease in treated areas.

How similar studies have performed: Oral vaccination of wild mice and past human OspA vaccines have lowered tick infection in some settings, but permanently encoding antibodies into wild mice is a novel and largely untested strategy.
