RESUMO
With approximately 225 million new cases and 800,000 deaths annually, malaria exacts a tremendous toll--mostly on African children under the age of five. Late-stage trials of an advanced malaria vaccine candidate--which, if approved, would become the world's first malaria vaccine--are under way, and it may be ready for use by 2015. This article recounts the pivotal roles in that achievement played by collaborations of nonprofit organizations, pharmaceutical companies, private and public donors, and countries whose citizens would benefit most directly from a vaccine. Just as it takes a village to raise a child, it has taken a huge number of stakeholders around the world to reach this point. Developing even more effective vaccines for malaria and other diseases will require continued hard work and creative thinking from scientists, regulators, and policy makers.

Human consumption is depleting the Earth's natural resources and impairing the capacity of life-supporting ecosystems. Humans have changed ecosystems more rapidly and extensively over the past 50 years than during any other period, primarily to meet increasing demands for food, fresh water, timber, fibre and fuel. Such consumption, together with world population increasing from 2.6 billion in 1950 to 6.8 billion in 2009, are major contributors to environmental damage. Strengthening family-planning services is crucial to slowing population growth, now 78 million annually, and limiting population size to 9.2 billion by 2050. Otherwise, birth rates could remain unchanged, and world population would grow to 11 billion. Of particular concern are the 80 million annual pregnancies (38% of all pregnancies) that are unintended. More than 200 million women in developing countries prefer to delay their pregnancy, or stop bearing children altogether, but rely on traditional, less-effective methods of contraception or use no method because they lack access or face other barriers to using contraception. Family-planning programmes have a successful track record of reducing unintended pregnancies, thereby slowing population growth. An estimated $15 billion per year is needed for family-planning programmes in developing countries and donors should provide at least $5 billion of the total, however, current donor assistance is less than a quarter of this funding target.
