Sian Aggett, Caroline Jones and Salla Sariola were members, along with the authors, of a working group on the ethics of PVM in health science research that was established in 2015 (Cambodia: Supplementary workshop to Oxford Tropical Network meeting). The concepts that were discussed among the working group at that time have contributed to shaping the themes that are described in this course.

Many of the examples of PVM projects from Vietnam were conducted in partnership with Nick Fernandez and Linh Phan of Fact & Fictions Films.

We are grateful to Pam Sykes for undertaking an expert peer review of the written content for this course and Jess Drewett for her tireless support with formatting and referencing.
