What this research studies

We are working on a new protein treatment, Fc3/SCR(19-20), that could be given as a yearly shot to prevent tick-borne illnesses like Lyme Disease and Relapsing Fever. Unlike traditional vaccines, this treatment works directly to stop the bacteria, meaning it should be effective for everyone, including those with weakened immune systems. Our initial work in mice shows that this shot can reduce the transmission of Lyme disease bacteria from infected ticks. The current focus is on improving the treatment so it lasts longer in the body, is safer, and can be given at a lower dose for season-long protection.

Who could benefit from this research

Good fit: This research is aimed at eventually benefiting anyone at risk of tick-borne diseases, including both healthy individuals and those with weakened immune systems.

Not a fit: Patients who have already contracted Lyme Disease or Relapsing Fever would not directly benefit from this preventative treatment.

Why it matters

Potential benefit: If successful, this yearly shot could offer a new way to prevent Lyme Disease and Relapsing Fever for many people, including those who are immunocompromised.

How similar studies have performed: While this specific protein is new, the research team has experience with similar plant-produced proteins, including one previously tested in clinical trials.
