 I retired at the end of 2013 and I'm now back to assist, to advise on the new initiative sponsored by Gates Foundation to try and take another look at the vaccine development against the same parasite I started working on 30 years ago. The parasite is rather complex. It has got various stages and when you look at malaria, which is a cousin to terraria, it has taken them probably longer. Some people remember using Vag, who used to work in the 60s on the spores white and also the chasms in malaria and even up to now we don't have a vaccine against it. It's the complex of the parasite and the various stages of the parasite that makes it very complicated. Because they are new technologies and one of these technologies is the genome analysis, which has provided a lot of antigens that can be used in combination to attack all the three stages of the parasite, that is the spores white, the chasms and possibly the bioplasm. If we could beat this disease, then the smallholder farmer would be able to keep a fridge in without any trouble and be able to sustain his or her family without worrying about the dipping, the control of ticks, the worry that the animal is going to die on me the next day and they lose all my savings.
