<unk> <unk>  is a vaccine against<unk> . No effective vaccine for the disease in humans has yet been developed.<unk> s, parasitic nematodes transmitted in soil, infect approximately 700 million humans, particularly in tropical regions of the world where endemic<unk> s include Ancylostoma duodenale and Necator americanus.<unk> s feed on blood and those infected with<unk> s may suffer from chronic anaemia and malnutrition. Helminth infection can be effectively treated with benzimidazole drugs (such as mebendazole or albendazole), and efforts led by the World Health Organization have focused on one to three yearly de-worming doses in schools because<unk>  infections with the heaviest intensities are most common in school-age children. However, these drugs only eliminate existing adult parasites and re-infection can occur soon after treatment. School-based de-worming efforts do not treat adults or pre-school children and concerns exist about drug resistance developing in<unk> s against the commonly used treatments, thus a vaccine against<unk>  disease is sought to provide more permanent resistance to infection.<unk>  infection is considered a neglected disease as it disproportionately affects poorer localities and has received little attention from pharmaceutical companies.
