The scientific research for this malaria vaccine has been going on since past 30 years. Phase-3 clinical studies were conducted between 2009 and 2014 in African nations. Children receiving 4 doses of this vaccine, experienced significant reductions in malaria and malaria-related complications in comparison to those who did not receive the vaccine.
In clinical studies, the vaccine was found to prevent 4 in 10 malaria cases, including 3 in 10 cases of life-threatening severe malaria. In addition, the vaccine also prevented 6 in 10 cases of severe malaria anaemia, the most common reason children die from malaria. Significant reductions were also seen in overall hospital admissions and the need for blood transfusions, which are required to treat severe malaria anaemia. These and other benefits were in addition to those already seen through the use of insecticide-treated bed nets, prompt diagnosis, and effective antimalarial treatment.
This malaria vaccine (RTS,S/AS01) is to be provided in 4 doses to children from 5 months of age up to 2 years. First 3 doses are given between 6 to 9 months of age, and 4th dose is given at 2 years of age.
The pilot of this malaria vaccine has been going on in Ghana, Kenya and Malawi since 2019. This malaria vaccine pilot began first in Malawi in April 2019, then in Ghana in May 2019, and finally in Kenya in September 2019. This Malaria Vaccine Implementation Programme generated evidence and experience on the feasibility, impact and safety of the RTS,S malaria vaccine in real-life, routine settings in selected areas of these three African nations: Ghana, Kenya and Malawi.
The pilot has proven that:
- Feasible to deliver: Vaccine introduction is feasible, improves health and saves lives, with good and equitable coverage of RTS,S seen through routine immunization systems. This occurred even in the context of the COVID-19 pandemic.
- Reaching the unreached: RTS,S increases equity in access to malaria prevention. Data from the pilot programme showed that more than two-thirds of children in the 3 countries who are not sleeping under a bed net are benefitting from the RTS,S vaccine.
- Layering the tools results in over 90% of children benefitting from at least one preventive intervention (insecticide treated bed nets or the malaria vaccine).
