Advances in Malaria Vaccines: What's New?

  Malaria is one of the most serious global public health threats, causing hundreds of thousands of deaths each year, mostly among children in sub-Saharan Africa. For decades, scientists have been working to develop an effective malaria vaccine, and recent years have brought several important advances in this field.

   Mosquirix (RTS,S)


  The most important success in the field of malaria vaccines is the development of Mosquirix (also known as RTS,S), which is the first and only malaria vaccine approved by the European Medicines Agency. In 2019, the WHO has initiated a pilot rollout of this vaccine in three African countries: Malawi, Kenya and Ghana.

  Mosquirix was developed to prevent malaria caused by the most dangerous of malaria parasites, Plasmodium falciparum. The vaccine has a success rate of about 30% in preventing cases of severe malaria in children.

  Although the effectiveness of Mosquirix is not perfect, it is an important step forward. The vaccine is believed to have the potential to reduce the number of cases of severe malaria, especially among children in sub-Saharan Africa.


   Other vaccine research


  While Mosquirix is currently the most advanced, there are many other malaria vaccines that are in various phases of research. Some are focusing on other malaria species, such as Plasmodium vivax, which is common in South Asia and Latin America.

  Another approach is to develop vaccines that block malaria transmission from human to mosquito. Such "transmission" vaccines could be key to eliminating malaria because they prevent the spread of the disease.

   Future prospects


  Although malaria vaccine development is fraught with challenges, progress in recent years has been promising. Mosquirix and other vaccines under study offer hope for more effective malaria control in the future.

  But even with the best vaccine available, malaria control will require an integrated approach, combining vaccination, mosquito control measures such as mosquito nets and antimalarial treatment.

  Advances in malaria vaccines are an exciting and dynamic area of research that has the potential to save millions of lives around the world. It is a key component of the global malaria control strategy and hopes for a future in which malaria is a disease of the past.
