Pneumonia vaccine ineffective in adults

Pneumonia vaccine ineffective in adults

A vaccine which is supposed to protect middle-aged and elderly people from pneumonia has been found to be completely ineffective.

More patients who took the "23-valent pneumococcal capsular polysaccharide vaccine," got pneumonia than those who had been given a placebo.

Swedish researchers, who published their report in the British medical journal The Lancet, found that the drug did nothing to prevent pneumonia in this age group.

Nineteen percent of the patients who received the vaccine developed pneumonia, while only 16% in the placebo group got the illness.

All the patients had previously had one bout of pneumonia and the drug was supposed to prevent another episode.

The researchers concluded that "Pneumococcal vaccination did not prevent pneumococcal pneumonia, pneumonia overall, or death (from all causes) in this study."
