I took this photo on May 29th, 2012 in Vanuatu, at a week-long workshop I led for Ni-Vanuatu Village Health Workers. We taught them simple tools and resources they can use to effectively teach their remote communities about HIV and AIDS and to carry out awareness and prevention. This is a picture of one of the Village Health Workers, Matilda, practicing using this poster to explain how the immune system works. This then leads the way into a discussion of how HIV works in the body.
