西亚试剂：Malaria vaccine cautiously recommended for use in Africa

The world's first vaccine against malaria should be rolled out in limited 'pilot' demonstrations in Africa, an advisory group to the World Health Organization (WHO) in Geneva said on 23 October. The demonstrations — involving up to 1 million children — are needed because the vaccine is ineffective against malaria unless children receive four doses spread out over 18 months, and even then offers only modest protection.

“If we can’t get four doses of this vaccine into children, we’re not going to be using it,” Jon Abramson, a paediatric infectious disease specialist at Wake Forest School of Medicine in Winston-Salem, North Carolina, and chair of the WHO Strategic Advisory Group of Experts (SAGE) on Immunization, said in a press briefing.

The decision to recommend the vaccine pilots — which the WHO’s director-general is expected to formally endorse in November — follows 28 years of development by the London-based drug firm GlaxoSmithKline (GSK) and other backers including the Bill & Melinda Gates Foundation in Seattle, Washington; together they have spent US$565 million on the drug.
