Testing tafenoquine to prevent babesiosis from tick bites
Evaluation of tafenoquine for prophylaxis of babesiosis caused by Babesia microti
This study is looking at whether tafenoquine, a medicine used to prevent malaria, can help older adults and people with weakened immune systems avoid getting babesiosis, a tick-borne illness caused by a parasite.

What this research studies
This research investigates the use of tafenoquine, a medication previously approved for malaria prevention, to see if it can effectively prevent babesiosis caused by the Babesia microti parasite. The study focuses on older adults and immunocompromised individuals who are at higher risk for severe symptoms from this tick-borne disease. Participants will receive a specific dosing regimen of tafenoquine to evaluate its effectiveness in preventing infection. The research aims to fill a gap in current prophylactic options for babesiosis, as no vaccine or chemoprophylaxis has been tested for this condition.
Who could benefit from this research
Good fit: Ideal candidates for this research are older adults over 50 years of age and immunocompromised individuals who are at higher risk for severe babesiosis.
Not a fit: Patients who are young and healthy, as they typically experience mild symptoms and may not require prophylaxis for babesiosis.
Why it matters
Potential benefit: If successful, this research could provide a new preventive treatment option for individuals at risk of developing severe babesiosis.
How similar studies have performed: While tafenoquine has been successfully used for malaria prevention, this specific application for babesiosis is novel and has not been previously tested.
