Wondering how you can protect yourself from seasonal flu? Or just weighing the pros and cons of the seasonal flu vaccine? Here are some of the fast facts about flu prevention that you've been looking for.
Influenza causes more than 200,000 people in the U.S. to be hospitalized every year. Up to 49,000 people die each year from flu-related causes. Prevention is key.
Ideally, you should get the seasonal flu vaccine by Thanksgiving -- the holiday season means hugs and kisses, which help...
"Immunizations are the greatest medical advance of the last one hundred years," says Richard L. Wasserman, MD, PhD, clinical professor in the department of pediatrics at the University of Texas Southwestern Medical School in Dallas.
"There's no question that immunizations have done more good for more people than any other medical intervention," agrees Ricardo U. Sorenson, MD, chair of the department of pediatrics, Louisiana State University Health Sciences Center in New Orleans.
Vaccinations have essentially wiped out diseases that once infected hundreds of thousands of people every year and killed tens of thousands. Yet many of us take immunizations for granted and may assume that, once we're adults, we don't need them anymore.
We do. While we may outgrow our need for booster chairs, we never outgrow our need for booster shots. So if you suspect you're not up-to-date with your vaccinations, it's time for a checkup.
Why Get Immunized?
Vaccines don't get the credit they deserve -- a testament to their success. Vaccines have so effectively wiped out many diseases that these illnesses seem as extinct as dinosaurs.
"How many people do you know who have had diphtheria or tetanus?" asks Wasserman. "Probably none. That's how well vaccines work."
Sorenson agrees that, nowadays, we have a casual attitude toward the diseases that terrified our grandparents. "People tend to forget how serious diseases like measles, mumps, rubella, and whooping cough were because they haven't experienced them," he tells WebMD.
But what's risky about our casual attitude is that these diseases are not extinct. In some parts of the world, they're common. If people stopped getting vaccinated in the U.S., they would become common here.
"I've seen the results of not getting vaccinated," says Wasserman. "I've seen children sick with vaccine-preventable diseases, like whooping cough and polio. It's tragic."
Why Do Adults Need Vaccinations?
Many vaccines work by introducing a dead or weakened version of a germ into your body, allowing your body to become familiar with it. Your immune system then reacts by creating antibody proteins custom-designed to fight that particular microbe. Then, if you ever come into contact with the real germ, the antibodies attack it. This is how vaccines grant you immunity.
