Children who receive a vaccine to prevent blood and ear infections, appear to be reducing the spread of pneumonia to the rest of the population, especially their grandparents and other older adults. Results of a new Vanderbilt study, funded by the Centers for Disease Control and Prevention (CDC), and published in the July 11 issue of the New England Journal of Medicine show infant vaccination against pneumococcal bacteria since 2000 has reduced pneumonia hospitalization by more than 10 percent across the board, with the most significant reductions at the extreme ends of the age spectrum.
