The painful skin condition shingles is on the rise in the U.S. leading some to wonder whether the use of the chickenpox vaccine is to blame.

A new oral antiviral drug may be a future tool in the global fight against measles, according to a new international study.

About half of Americans agree with at least one medical conspiracy theory, a new study suggests.

One woman's uncommon ability to fight her HIV infection may provide new insights for developing a vaccine that triggers a special immune response against the viral disease, researchers said.

Public health messages aimed at increasing vaccination rates may actually make parents less likely to vaccinate their children, new research finds.

Flu has been particularly bad this year among young and middle aged adults, according to a new report from the Centers for Disease Control and Prevention.

As flu activity starts to rise in parts of the country, about 40 percent of Americans have already received a flu shot, according to the Centers for Disease Control and Prevention.

Borrowing ideas from weather forecasting, researchers have developed a system to predict, weeks in advance, when a city will see the peak of its seasonal flu outbreak.

Data from around the United States from the last 100 years has been compiled and analyzed to uncover important health trends.

By studying how the flu virus operates, researchers hope to develop more effective vaccines.
