Antibiotics are the first and most potent line of defense against bacterial diseases. But their overuse and abuse in the few decades, especially to treat viruses that don't respond to antibiotics, have led to a dangerous resistance to even common infections.
The CDC has made the appropriate use of antibiotics a cornerstone of its Get Smart About Antibiotics educational campaign, now in its third year. CDC experts Lauri Hicks, DO, a medical epidemiologist, and Arjun Srinivasan, MD, associate...
Ongoing stress, such as being in a difficult relationship, living with a chronic disease, or being a caregiver can take its toll on your immune system. Over time, it can make you more vulnerable to illnesses, from colds and flu to chronic diseases such as diabetes and heart disease. Chronic stress seems to age the immune system, studies show, making you more likely to get a cold or the flu, chronic diseases such as diabetes, and heart disease.
Everyone goes through stress. What matters is how you handle it. Getting better at managing stress can help. Even something as simple as deep breathing can lessen the effects of stress. Or try other relaxation techniques, such as:
Myth: Getting a flu shot weakens your immune system and makes you more likely to get the flu.
Totally untrue. Getting a flu vaccine prepares your immune system for the flu.
A flu vaccine teaches your immune system to recognize that virus as a threat. While some people may still get the flu after having a flu shot, they'll probably have a milder form of the illness -- and it's not because they got the vaccine. A milder form of the flu is still possible despite getting vaccinated because antibodies made in response to the vaccine can still provide some protection.
So why do people swear a flu vaccine gave them the flu? Some may mistake the occasional side effects of the vaccine (fever, aches) for flu symptoms. And the time of year people are most likely to get the vaccine is when colds and other respiratory illnesses are common. If you get the vaccine and then get sick with an unrelated bug, you may assume, incorrectly, that the vaccine caused the illness.
