Stopping Lyme disease by vaccinating wild mice that infect ticks
Efficacy of novel reservoir-host targeted bait formulations against a tick-borne pathogen
This project tests bait vaccines put out for wild mice to lower the number of infected ticks and reduce people's risk of Lyme disease.

What this research studies
This work aims to block Lyme disease at its source by giving vaccines to animals that maintain the bacterium, especially white-footed mice. Researchers create bait formulations containing purified proteins from Borrelia burgdorferi and feed them to both lab and reservoir mouse models. They will track whether vaccinated mice pass the bacterium to ticks less often and whether ticks collected later carry less infection. The team measures infection in ticks and mice to see if the bait approach could reduce environmental Lyme risk for people in treated areas.
Who could benefit from this research
Good fit: People living or working in areas with many black-legged ticks and high Lyme disease rates are the main group who could benefit from this approach.
Not a fit: People who live in areas without black-legged ticks or who have no exposure to tick habitats would likely get no direct benefit.
Why it matters
Potential benefit: If successful, this could reduce infected ticks in the environment and lower people’s risk of getting Lyme disease.
How similar studies have performed: Previous animal work showed that purified Borrelia lipoproteins can protect mice from infection when given by injection, but using bait to vaccinate wild reservoir animals is less tested.
