Brief Summary

The goal of this clinical trial is to assess the efficacy and safety or a revised weight band tafenoquine dose in vivax malaria patients. The main question\[s\] it aims to answer are: * is a revised weight-based TQ regimen (TQRevised: target dose 7.5mg/kg) non-inferior to high dose primaquine (7mg/kg over 7 days) * is a revised weight-based TQ regimen (TQRevised: target dose 7.5mg/kg) superior to fixed dose tafenoquine (300mg) * is the tolerability and safety of TQRevised acceptable * is TQRevised acceptable and feasible Participants will receive a tafenoquine target dose 7.5mg/kg in weight bands. Researchers will compare this to patients receiving a fixed dose tafenoquine and high dose primaquine to see if safe and effective.
