Finally, the world has a public health tool that it has been searching for for more than a century: a safe vaccine against malaria (or malaria) that protects at least two-thirds of the children who receive it from the development of the disease. mortal.
In fact, in a display of abundance, the population now has two alternatives . Last week, the World Health Organization (WHO) recommended a vaccine formulation called R/Matrix-M , developed by the University of Oxford and the Serum Institute of India, follo Chinese Overseas Asia Number Data wing the earlier publication of Phase results that They indicated an efficiency of to % ; The study has not yet been peer-reviewed. This occurs just three months after the launch of another vaccine called RTS,S/AS , developed by GlaxoSmithKline (GSK), which achieved % efficacy . The WHO approved this formula in October
How malaria vaccines work
The RTS,S vaccine is beginning to be distributed in countries in Africa. After some regulatory work, the R vaccine is expected to debut next year . Together, they would make an extraordinary difference to the survival of children in tropical countries, although experts say it is too early to abandon traditional tools, such as mosquito nets, that have somewhat kept malaria at bay until now.
Up to , people die from malaria each year. It is a huge economic burden for countries,” says Lisa Stockdale, senior immunologist at the Jenner Institute at the University of Oxford and member of the R research team. “If we manage to vaccinate everyone, there will be enormous potential to save lives.”
According to information from the Pan American Health Organization (PAHO), in , the number of malaria cases reported in the Americas region, at ,, was % lower than the previous year. This was also reflected in the number of deaths, decreasing from in to in It is noteworthy that this year Belize received the WHO certificate as a malaria-free country after three consecutive years without indigenous cases being recorded. Paraguay preceded it in , Argentina in and El Salvador in , demonstrating that “involving local communities, strengthening primary health care and guaranteeing sustainable financing” to combat contagion and disease contribute to its eradication, as stated in April by Dr. Jarbas Barbosa, director of PAHO, within the framework of World Malaria Day.
The effective vaccine has taken so long to find because malaria is a uniquely cunning enemy. The disease is caused by a shape-changing parasite. It enters the body through a mosquito bite, migrates to the liver, multiplies there and then moves to the red blood cells of the circulatory system. In each of these stages, it adopts a different structure and produces thousands of different proteins. Interfering with this multi-phase infection is a complex maneuver, much more difficult than teaching the body to protect itself against viruses or bacteria.
