Africa: Pneumococcal vaccine works even in HIV patients

Trials of a vaccine against the most common cause of pneumonia and meningitis — both leading causes of death in HIV sufferers in Africa — have proved so successful that scientists say it could be a major breakthrough in combating the diseases. The new vaccine protects against Streptococcus pneumoniae which causes pneumonia and, when it invades the bloodstream and brain, causes septicaemia and meningitis.
