First massive malaria vaccine to be tested on kids in Africa
nairobi — A new malaria vaccine will be tested on a large scale in Kenya, Ghana and Malawi, the World Health Organisation said on Monday, with 360,000 children to be vaccinated between 2018 and 2020.
The injectable vaccine RTS,S could provide limited protection against a disease that killed 429,000 people worldwide in 2015, with 92 per cent of victims in Africa and two-thirds of them children under five.
“The prospect of a malaria vaccine is great news. Information gathered in the pilot will help us make decisions on the wider use of this vaccine,” said Dr Matshidiso Moeti, the WHO’s regional director for Africa.
The vaccine should be used alongside other preventative measures such as bed nets, insecticides, repellants and anti-malarial drugs, the WHO said.
“Combined with existing malaria interventions, such a vaccine would have the potential to save tens of thousands of lives in Africa,” Moeti said.
The vaccine, also known as Mosquirix, has been developed by the British pharmaceutical giant GlaxoSmithKline (GSK) in partnership with the PATH Malaria Vaccine Initiative, and the large-scale threecountry pilot will test it on children aged five to 17 months.
The drug passed previous scientific testing — including a phase three clinical trial between 2009 and 2014 — and was approved for the pilot programme in 2015.
The aim of the trial is to assess the effectiveness of the vaccine as well the feasibility of its delivery to populations at risk as four successive doses must be given on a strict timetable.
The immunisation cycle is not in sync with routine childhood inoculations against diseases such as hepatitis, measles and meningitis, with injections required at five months, six months, seven months and two years.
Symptoms of malaria include fever, muscle pain and headache as well as vomiting and diarrhoea.
While RTS,S does not promise full protection against the mosquito-borne disease it is the most effective potential vaccine so far developed. —
