A vacina que custa 2,50 libras a dose e já protege crianças em 20 países

Malaria comes from a mosquito bite. It kills children under five, above all in Africa. For many years, scientists try to make a vaccine and it never works well enough.

Now one vaccine works. Its name is R21. A team at Oxford University makes it. It protects about seventy-five or eighty children out of one hundred. It costs about two pounds and fifty pence for each dose. And it stays good for two years in a normal fridge. That last part matters, because many clinics are far from a city.

Today twenty countries in Africa use this vaccine. Babies get it from five months old. In July 2026, Europe gives a big prize to the inventor, Adrian Hill. But the prize is not the news. The news is that a poor country can pay for it.
