Question

DID you get a flu shot this year? For the first time, the Centers for Disease Control and Prevention in the US is recommending that all children aged from 6 months to 18 years receive the flu vaccine£®

Vaccines battle diseases caused by bacteria and viruses£®A weakened form of the germ £¨Î¢ÉúÎ is introduced into the body£®The body makes special substances called antibodies to fight the germs£®If the actual germs were to attack, the antibodies would fight it£®

   Because there are many kinds of flu viruses, scientists must create a new vaccine  formula £¨·½³Ìʽ£© each year£®Researchers must make a prediction£®

It is like forecasting the weather£®Sometimes they are right on, and sometimes they are off£®But even when the vaccine does not closely match circulating flu types, it can make the illness less serious£®

   "The flu vaccine is not as effective as the polio £¨Ð¡¶ùÂé±ÔÖ¢£© vaccine or the measles vaccine," says Dr William Schaffner of Vanderbilt University School of Medicine£®"It's not a great vaccine, but it is quite a good vaccine£®"

But a flu vaccine doesn't work for everyone£®There are certain people who should be careful about taking it£®

Because the vaccine is produced in eggs, those who are allergic £¨¹ýÃôµÄ£© to eggs should not take it£®If you have a fever, you should wait until you recover£®

Some people are afraid that they might get the flu from the flu shot£®Scientists say that it is not possible, because the viruses in the flu shot are inactivated£®But some minor side effects such as low-grade fever and body ache could occur£®If they do, they begin soon after the shot and usually last only one to two days£®

Did you know?

Smallpox was the first disease people tried to prevent by putting a virus into a healthy person£®In 1796, English scientist Edward Jenner placed some infected material under a boy's skin£®
