ABSTRACT
As well as this, hopes that genetic engineers might soon develop the world’s first malaria vaccine, a long-sought goal, have been questioned recently by several scientists. ‘There are so many strains of malaria parasite,’ said one scientist, ‘and each is able to alter its chemical surface and trick its way past the body’s defences. We’d need a remarkable vaccine to cope with that. However, a malaria vaccine is now undergoing human trials and may be available for use if proved successful.’
