Each year, more than 2 million children die from just four illnesses: malaria, pneumonia, diarrhea caused by rotavirus, and Japanese encephalitis. To mark World Immunization Week, we’re profiling vaccine projects in our extensive portfolio that aim to protect children from these illnesses. Today, we look at the need for a new kind of vaccine against pneumonia.
Pneumonia kills more children worldwide than any other disease. Last year, it took the lives of more than a million children—3,000 every day—primarily in the world’s poorest countries.
Poor access to sanitation and safe drinking water, a lack of health care, and inadequate diagnostic tools all contribute to pneumonia’s toll. Often, parents don’t recognize children’s symptoms in time, and when they do, lifesaving care may be miles—or even days—from their homes.
Meeting these challenges requires a combination of approaches. For more than ten years, vaccines have been a particularly powerful ally. Last year, immunization against the leading cause of pneumonia, the pneumococcus bacterium, saved thousands of lives in more than 100 countries. Yet existing vaccines are complicated to manufacture, too expensive for many low-resource countries, and don’t offer complete protection against disease. To beat pneumonia, we need to keep improving our tools. Continue reading
