Researchers at the Radboud university medical centre in Nijmegen have been running trials of a medicine that seems to give long-term protection against malaria, news agency ANP reports.
The medicine chloroquine, which had fallen into disuse, was given to test patients for three months. In the same period they were bitten by malaria-carrying mosquitoes. An immune response built up which was still working 2.5 years later, the researchers say.
Professor Robert Sauerwein, who is leading the research, says the tests provide a blueprint for the manufacture of an effective vaccine for the disease, which kills millions of people every year.
