Pneumonia Vaccine for Children Also Protects Older Adults

Researchers led by Dr. Marie Griffin of Vanderbilt University found that children who receive the pneumococcal vaccine pass the protection on to grandparents and older adults. Based on an analysis of data covering national hospitalizations from 1997 to 2009, the researchers found that the vaccine reduced pneumonia infections in children and pneumonia hospitalizations in older adults. “It is one of the most dramatic examples of indirect protection, or herd immunity, we have seen in recent years,” says Griffin, indicating that it is more effective in protecting the elderly than the vaccine currently recommended for them. The study is published in the New England Journal of Medicine.
