They also found out that the vaccine continues to provide
protection 18 months after its injections were given.
The manufacturer, GlaxoSmithKline (GSK), has now applied for
regulatory approval, making this the first vaccine to reach this step.
The company has asked the European Medicine’s Authority to
approve it for global use.
It said together with other preventative measures, such as
bed nets and insecticides, the vaccine could represent a huge step forward in
malaria control.
Scientists are investigating whether a booster could further
improve the chances of success.
Professor Sanjeev Krishna of St George’s University of
London, who was not involved in the research but reviewed the paper for the
journal, said “this is a milestone. The landscape of malaria vaccine
development is littered with carcasses, with vaccines dying left, right and
centre.
“To get to this stage is very encouraging indeed. We eagerly
await the next results to see how long-lasting protection is and whether a booster
adds further potential.
“We need to keep a watchful eye for adverse events, but
everything appears on track for the vaccine to be approved as early as next
year.”
Professor Brian Greenwood of the London School of Hygiene
and Tropical Medicine, who was involved in the research, told the British
Broadcasting Corporation (BBC) that “to finally get a malaria vaccine licensed
would be a huge leap forward.
“Though it does not provide 100 per cent protection, for
areas where malaria is commonplace, this has the potential to have a real
impact.”
GlaxoSmithKline (GSK) is developing RTS,S with the
non-profit Path Malaria Vaccine Initiative, supported by funding from the Bill
& Melinda Gates Foundation.
