Pfizer's Prevnar prevents pneumonia in elderly - study

Pfizer Inc said on Monday that Prevnar 13, its blockbuster vaccine against childhood infections, prevented pneumonia outside of hospitals in people age 65 and older, in one of the largest drug trials ever conducted. The 85,000-patient study, called CAPiTA, also showed that Prevnar 13 prevented invasive pneumococcal disease, meaning infections of Streptococcus pneumonia bacteria in the bloodstream and other normally sterile sites in the body. Wall Street analysts have predicted that success of the trial would boost annual sales of Prevnar 13 by $1 billion or more, as doctors steer elderly patients to the product. "We expect the U.S. and other developed markets to broadly recommend adult use of the product," given favorable results from the study, J.P. Morgan analyst Chris Schott said in a research note.
