The WHO has rolled out the world’s first malaria vaccine to all children in Africa. The vaccine was developed way back in 1987. It is only 30% effective and administering it is cumbersome because it requires four doses and protection fades after four months. But given that there are more that 200 million cases and 400,000 deaths per year due to malaria, the impact could still be large.
Because of the heat and poverty, many children in Africa sleep out in the open without protective nets covering them, making them highly vulnerable to mosquito bites.
Malaria is a major scourge and the world needs a much better malaria vaccine. Maybe the new vaccine-making techniques developed to deal with the coronaviruses can be adapted to find one for malaria.
