RTS,S VaccineA new vaccine known as the RTS,S vaccine is currently being piloted in the African nations of Ghana, Malawi and Kenya.  The RTS,S vaccine has been in development for over 32 years. It is the first malaria vaccine that has been shown to provide young children with partial protection from malaria.

What is Malaria?

Every single year, the malaria virus kills one million people around the world. It is estimated that 300-600 million people suffer from malaria every year. Additionally, 90 percent of malaria cases occur in Sub-Saharan Africa. The majority of malaria’s victims are children under the age of five.

According to UNICEF, Malaria kills one child every thirty seconds, which is about 3,000 children every single day. Malaria hinders children’s social development and schooling. Furthermore, malaria is a major cause of poverty. For example, the cost of malaria control and treatment actually slows economic development in Africa by 1.3 percent.

RTS,S Malaria Vaccine Pilots

In clinical trials, the RTS,S vaccine was found to prevent about 4 out of 10 malaria cases. Additionally, it proved to prevent 3 in 10 cases of severe, life-threatening malaria. The malaria vaccine has also been shown to reduce severe malaria anemia by 60 percent. Severe malaria anemia is the most prevalent reason that children die from malaria.

The organizations of Unitaid, Gavi, the Vaccine Alliance and the Global Fund to Fight Aids, Tuberculosis and Malaria funded and supported these pilots.

Impact

Currently, an estimated 360,000 children are expected to receive the RTS,S vaccine through immunization programs in certain areas of Malawi, Ghana and Kenya. However, the main weakness of the immunization programs is in how they store and transport the vaccines. The effectiveness of a vaccine is dependent on whether it is in a properly-functioning cold chain. This refers to a system of transporting and storing vaccines at the proper temperatures from when they are manufactured to when they are used.

To ensure that vaccines properly fulfill their duty of vaccinating children from malaria, there needs to be an increased focus on the protection and storage of these vaccines in their proper cold chains. It is vital to invest in proper storage equipment and maintenance of that storage equipment. This equipment will retain the vaccine’s efficacy. It is also crucial to invest in roads and infrastructure so the vaccines can be properly transported to those in need.

Innovation

A technological innovation that has changed and improved the transportation of malaria vaccines is the use of drones. The Rwandan tech firm Zipline has already launched drones that are used to transport medication, vaccines, blood and other essential health care items.

Starting out in Rwanda, the firm has also expanded its lifesaving services into Ghana. The drones fly at 100 kilometers and are able to make deliveries in 30 minutes that otherwise could take five hours by car. The drones also are able to fly through any type of terrain. Therefore, they can easily reach remote villages without requiring any sort of local infrastructure at the scene. ZipLine is able to make up to 500 delivers a day. Thanks to its services, ZipLine has provided 13 million people instant access to urgent, life-saving treatments.

The RTS,S vaccine is an effective vaccine that is vital in protecting young children from malaria. By drastically reducing cases of severe malaria anemia, the RTS,S vaccine is saving lives. To continue saving lives and to further build the efficacy of the vaccine, it is crucial to focus on investing in the proper infrastructure for storage and transportation of the vaccine.
