If you actually look at the first page of search results, it provides information from credible sources such as the CDC that refute what LeeMark says. Basically, a flu shot is a crapshoot - it is not as effective in preventing infection as other vaccines. There is credible scientific proof. In some years the percentage of true effectiveness in the population is in the single digits. There is some evidence that shows that the elderly benefit more than others.
From the CDC (
CDC - Seasonal Influenza (Flu) - Key Facts About Seasonal Flu Vaccine):
"The ability of a flu vaccine to protect a person depends on the age and health status of the person getting the vaccine, and the similarity or "match" between the viruses or virus in the vaccine and those in circulation."
From someone who actually knows about medicine (
Chemistry, How Things Work - Articles):
"The Centers for Disease Control (CDC) is looking at whether or not the flu vaccine is effective. Preliminary results indicate you'll get just as sick (with colds, flu, flu-like illnesses) if you got the vaccine than if you didn't. Why doesn't the vaccine work? In order to understand the answer, you'll need to understand some specifics about the flu vaccine and a bit about how immunity works. "
Random news story (
amednews: Research at odds over impact of flu vaccine :: Jan. 19, 2009 ... American Medical News):
"Various studies offer wide-ranging conclusions. One, for instance, found that seasonal influenza vaccine halves elderly deaths from any cause in the winter months. But another found it has no impact at all on this age group's health. These and other conflicting findings are pushing public health officials and scientists to look for better ways to quantify the preventive's impact."
Another (
Flu vaccine effectiveness lower than usual | Health | Reuters):
""The vaccine is designed to protect against three influenza strains -- two from Type A, an H1N1 and an H3N2 version, and one for Type B. "This season, we had a less-than-optimal match in two of the three vaccine components," Dr. Dan Jernigan of the CDC's Influenza Division told reporters.
For the 1997-98 season, the vaccine effectiveness was effectively zero," Jernigan said."
This is stuff that someone "who actually knows something about medicine" would actually know.
