As new and better vaccines are developed, they must be tested for safety and effectiveness. New vaccines for children must also be tested along with currently available vaccines.

With autumn right around the corner, flu season is lurking around the bend. Now is a good time to make plans to protect your family from the flu.

One of the childhood vaccinations recommended by the CDC is the one for pneumococcal bacteria. This bacteria can cause some types of meningitis.

All types of preventive medicine offer benefits and risks, and vaccines are no exception. But often, the risks related to getting a disease may be greater than the risks of the vaccine.

People with HIV have weakened immune systems, so they are more likely to catch harmful diseases like tuberculosis. However, new research suggests that a certain prevention therapy could significantly reduce that risk.

Although tuberculosis (TB) is a preventable and curable disease, it still causes death and illness, especially in developing countries. And even developed countries are not out of the danger zone, particularly as immigration and travel help spread the disease. 

Most people get the flu vaccine for the obvious reason: to protect them from the flu. But there may be other benefits to the shot as well.

Ohio is in the midst of an outbreak of Legionnaire's disease, a serious illness caused by the bacteria Legionella .

When H7N9, a strain of bird flu, began infecting people in China last spring, officials and scientists worldwide tried to quickly learn more about this new virus.

Vaccines protect people from diseases. Pregnant women who get vaccinated can pass on that protection to their developing babies. And it seems some of that protection may last even after birth.
