We investigate why pneumococcal disease is a major global health problem, killing more than 800,000 children every year. In industrialised nations a vaccine has dramatically reduced child deaths caused by the disease. Now scientists have tested a new vaccine that has been proven to work. It could save thousands of lives in the developing world. In this film we visit Alaska where doctors have been studying the impact of vaccination and India where the vaccine is desperately needed.
