Fear of a flu epidemic is a constant concern for scientists and researchers. A new study may help reduce those fears thanks to a “natural killer.”

It's the medical breakthrough that disease experts have long dreamed about: A “universal” flu vaccine that would last for years and protect against all strains of flu virus.

Despite long traditional use, there is limited data about the influence of garlic on cold and flu treatment. Recent clinical trials are illuminating how this plant keeps us healthy.

The flu vaccine can do more than protect a pregnant mother and her baby from the flu. It also appears to reduce the risk of having an underweight baby.

Mothers now have even more reason to breastfeed. A new study shows breastfeeding led to better lung function in children, especially in children of mothers with asthma.

Unfortunately many people who need a lung transplant die waiting. This might be different if transplants were given based on need and not on location.

Your annual flu shot protects you against the three strains of flu viruses expected to be common that year. But what if there was one vaccine that protect you against every type of flu?

Germs and sick coworkers may not be the only way to get sick in the office. Chemicals in the paint, furniture and carpet may be also causing you to get sick.

Smoke inhalation can cause serious lung damage and even death. A new study has shown that the body responded unexpectedly to the damage caused by smoke inhalation.

If you feel like you're coming down with something like flu, what source of information do you turn to first? For many people, the answer is Google.
