Malaria has been one of the biggest scourges on humanity for millennia and mostly kills babies and infants.

Having a vaccine – after more than a century of trying – is among medicine’s greatest achievements.

The vaccine – called RTS,S – was proven effective six years ago.

Now, after the success of pilot immunisation programmes in Ghana, Kenya and Malawi, the World Health Organization says the vaccine should be rolled out across sub-Saharan Africa and in other regions with moderate to high malaria transmission.

Trials, reported in 2015, showed the vaccine could prevent around four in 10 cases of malaria, three in 10 severe cases and lead to the number of children needing blood transfusions falling by a third.

However, there were doubts the vaccine would work in the real world as it requires four doses to be effective.

“From a scientific perspective, this is a massive breakthrough, from a public health perspective this is a historical feat,” said Dr Pedro Alonso, the director of the WHO Global Malaria Programme.

“We’ve been looking for a malaria vaccine for over 100 years now, it will save lives and prevent disease in African children.”
