I do think that all kinds of information in the subject is important. In movies is one way of doing it but maybe not the most effective for getting to the public in Africa.

The other day I heard about HIV vaccine. A researcher team in Thailand has managed to generate response from the immune system on a vaccine, which was some kind of break through. 30% of the sample reacted positively to the vaccine. This research team is furthest in the development of HIV vaccine and it seems that there still is a long way to go before this solution is available on the market (source http://www.sr.se/vetenskapsmagasinet). Information programs are the best solution for now..
