The first-ever malaria vaccine is 35 years and billions of dollars in the making. It’s less than 40% effective.

Hundreds of thousands of children across malaria-stricken regions of Kenya, Malawi, and Ghana are receiving the world’s first ever malaria vaccine, which Western health experts laud as an exciting new tool in the global fight against the disease. But after 35 years and hundreds of millions of dollars spent in development, some African health professionals are wondering: Is the vaccine worth the cost?

One study estimated that on average, the vaccine will be nearly three times as expensive as distributing bed nets to achieve the same improvements in health. With limited funding available, some in Kenya worry that the money is being misspent. “The nets—that’s our need, for now.”

First, a lioness ventured into the city as a decoy to draw officials away from her cubs that were lost in an army barracks.

Then, just weeks later, a pride of six lions breeched a fence into a pasture killing as many as 120 goats and sheep. One lion lost his bearings and ended up on a major highway, injuring a man before finding his way back into Nairobi National Park, located adjacent to Kenya’s capital city.

Now, this week, a popular lion named Mohawk ventured some 20 miles (32 kilometers) south of that park only to be surrounded and harassed by onlookers. When he responded by attacking one of them, he was shot and killed by park rangers.
