As a symptom of illness, sore throat rivals fatigue for being both commonplace and a potential sign of catastrophe. Usually, having a sore throat is nothing to worry about -- most are caused by cold and flu germs. In rare cases, however, a sore throat can signal something much more serious. One of the first symptoms of infection caused by the dreaded ebola virus, for example, is a sore throat.
And strep bacteria, a common cause of sore throat, especially in children, can spread like wildfire if...
Truth: You can't get the flu by having a flu
shot. The flu shot is made of killed virus and therefore
cannot cause the flu. And the weakened viruses in the flu nasal spray vaccine can cause symptoms similar to a cold, but they can't cause the flu.
Myth: The vaccine causes unpleasant side
Truth: The vaccine causes no side effects in
most people. Earlier vaccines (1940s to 1960s) did have more
unpleasant side effects, but this is rare now. And an intradermal flu shot is available. A smaller needle is used, and the vaccine is injected into the skin instead of the muscle to reduce discomfort at the time of the shot.
Myth: The vaccine is ineffective because some
people had a flu-like illness after getting a flu vaccine.
Truth: Although getting the vaccine prevents
most people from becoming ill with the flu, some people still become infected.
This may occur because a person is exposed to the virus before getting a
vaccination or before it has taken effect, or because the vaccine does not
match the circulating virus closely enough. A mild illness similar to a cold also can be caused by the live, weakened viruses in the influenza nasal spray vaccine. But any illness is usually
milder than it would be without having had the vaccine.
