This is the best summary I could come up with:

A cheap malaria vaccine that can be produced on a massive scale has been recommended for use by the World Health Organization (WHO).

That makes it hard to build up immunity naturally through catching malaria, and difficult to develop a vaccine against it.

Dr Matshidiso Moeti, the WHO regional director for Africa, said: "This second vaccine holds real potential to close the huge demand-and-supply gap.

“Delivered to scale and rolled out widely, the two vaccines can help bolster malaria prevention, control efforts and save hundreds of thousands of young lives.”

Data that has been published online, but has not been through the usual process of scientific review, shows the R21 vaccine is 75% effective at preventing the disease in areas where malaria is a seasonal.

Prof Sir Adrian Hill, director of the Jenner Institute in Oxford where R21 was developed, said: “The vaccine is easily deployable, cost effective and affordable, ready for distribution in areas where it is needed most, with the potential to save hundreds of thousands of lives a year.”
