New malaria vaccine results raise hopes of mass rollout. A booster dose of a new malaria vaccine maintains a high level of protection against the disease, researchers said Thursday, expressing hopes the cheap jab could be produced on a massive scale in a matter of years.<\/p>\n

The international research team suggested the vaccine, developed by Britain\u2019s Oxford University, could represent a turning point in the fight against the mosquito-borne parasitic disease, which killed 627,000 people — mostly African children — in 2020 alone.<\/p>\n

Last year a different vaccine produced by British pharmaceutical giant GSK became the first to be recommended for widespread use against malaria by the World Health Organization<\/a>, and has now been administered to more than a million children in Africa.<\/p>\n

However research has found that the effectiveness of GSK\u2019s vaccine is around 60 percent, and significantly wanes over time even with a booster dose.<\/p>\n

Oxford\u2019s R21\/Matrix-M vaccine meanwhile was found to be 77 percent effective at preventing malaria in research published last year — the first time the WHO\u2019s roadmap goal of 75 percent had been met.<\/p>\n

For the research, 450 children aged five to 17 months in Burkina Faso — where malaria accounts for around 22 percent of all deaths — were given three doses in 2019.<\/p>\n

They were split into three groups, two receiving different doses of the Matrix-M adjuvant, a vaccine ingredient patented by Novavax also used in the US biotech firm\u2019s Covid jab. The third control group received a rabies vaccine.<\/p>\n

Ahead of the 2020 rainy season – when malaria cases surge – 409 children returned to get a booster shot.<\/p>\n

For the group that received the higher dose of adjuvant, the booster rose the protection level to 80 percent, according to the results of a phase 2b trial published in The Lancet Infectious Diseases journal on Thursday. The lower dose had 70 percent efficacy.<\/p>\n

And crucially, the booster returned antibody levels to a similar level seen after the first round of doses, the study said.<\/p>\n

The study\u2019s lead investigator Halidou Tinto of the Burkina Faso health research institute IRSS said, “It is fantastic to see such high efficacy again after a single booster dose.”<\/p>\n

Tinto, who was involved in trialling both malaria vaccines, said GSK\u2019s vaccine had an optimal efficacy of around 60 percent. “So I can confirm that R21 is doing much better,” he told a press conference.<\/p>\n","protected":false},"excerpt":{"rendered":"
