Sayana Press is a pre-packaged shot, costs a buck, lasts three months, and could revolutionize the way women in poor countries approach birth control, reports the BBC. A three-way deal between the Bill and Melinda Gates Foundation, Pfizer, and the Children's Investment Fund Foundation is looking to make Sayana Press available in some 69 countries, adds AFP. The single-use shot is based on Depo Provera, and its simplicity lends itself to application even in rural or non-clinic situations, notes the Independent. "The reality is that today, over 200 million women around the world want to prevent or time their pregnancies but lack the means to do that," says a doctor with the Gates Foundation. (Meanwhile, it's hardly Gates' only foray into birth control.)
