Although there are effective drugs to treat worm infections, they’re not universally available and can’t prevent future infections. Now a team of scientists are trying to develop a vaccine against one of the most damaging parasites, hookworm. It will be the first vaccine against a multi-cellular organism. 58 year old fisherman João Conceicao Silva has grown up in Marau in northern Brazil. He knows the symptoms of one of the main health complaints in the town only too well. \"Everybody has worms. I feel them on my skin. They start biting. It stings. I scratch and soon there are small lumps, then it begins. You feel sick in the stomach, throw up and there are the tiny worms. If it is not treated, it goes on to make you tired. Makes your body weak. The stomach gets more and more worms and the person dies. Specially this kind of worm\". He has lost count of the number of times he has had worms. For him, it's just a fact of life – along with being poor and struggling to make ends meet. \"I do many jobs. When there's work I do it. When there isn't. I get a net and go fishing. That's what I do unless there are odd jobs. Sometimes I sell coconuts. I don't make a good living but I get along. It's hard but I get along. And it's even harder because of the worms. They sap whatever energy he has. \"I've never had a medication that worked. You can see one of my grandsons has rashes and they're due to worms. It's connected to the climate of the region\". João and his family live in a very simple house they built themselves, which he believes is partly a cause of his problems. This is my cistern. We built it ourselves. The water is not good but we drink from it. We boil the water to drink because there's no other choice. We have to drink from this one. The worms come from the water. When the water is not treated there are microbes and the worms come from the microbes. The worms are affecting the development of my grandchildren and if you treat he water, their development will be better. João's understanding of the biology may not be completely accurate however he is completely right when he talks about hygiene and lack of clean water being a cause of parasite problems in his community. Access to clean water and education about how these worms are transmitted are essential for his communities' development.\n
