WHO backs malaria vaccine rollout
THE World Health Organization (WHO) said on Wednesday the only approved vaccine against malaria should be widely given to African children, potentially marking a major advance against a disease that kills hundreds of thousands of people annually.
The WHO recommendation is for RTS,S - or Mosquirix - a vaccine developed by British drugmaker GlaxoSmithKline.
Since 2019, 2.3 million doses of Mosquirix have been administered to infants in Ghana, Kenya and Malawi in a large-scale pilot programme coordinated by the WHO. The majority of those whom the disease kills are under age five.
That programme followed a decade of clinical trials in seven African countries.
“This is a vaccine developed in Africa by African scientists and we’re very proud,” said WHO director-general Tedros Adhanom Ghebreyesus.
“Using this vaccine in addition to existing tools to prevent malaria could save tens of thousands of young lives each year,” he added, referring to anti-malaria measures like bed nets and spraying to kill mosquitoes that transmit the disease.
One of the ingredients in the Mosquirix vaccine is sourced from a rare evergreen native to Chile called a Quillay tree. Reuters reported on Wednesday https://www.reuters. com/business/healthcare-pharmaceuticals/ chilean-tree-holds-hope-new-vaccines-ifsupplies-last-2021-10-06 that the long-term supply of these trees is in question.
Malaria is far more deadly than COVID-19 in Africa. It killed 386,000 Africans in 2019, according to a WHO estimate, compared with 212,000 confirmed COVID-19 deaths in the past 18 months.
The WHO says 94 per cent of malaria cases and deaths occur in Africa, a continent of 1.3 billion people. The preventable disease is caused by parasites transmitted to people by the bites of infected mosquitoes. Symptoms include fever, vomiting and fatigue.
