What is Influenza? 

Flu is a contagious disease that spreads around the world – China included – every year, usually between October and May. Anyone can get the flu, but it is more dangerous for some people. Flu can cause fever and chills, sore throat, muscle aches, fatigue, cough, headache, runny or stuffy nose, vomiting and diarrhea. Flu can also cause medical complications such as pneumonia, bronchitis, sinus infections and ear infections.

Why Get the Flu Vaccine? 

The influenza vaccine can prevent influenza (flu). Each year thousands of people in China die from flu, and many more are hospitalized. Flu vaccine prevents millions of illnesses and flu-related visits to the doctor each year.

Who Should Get Vaccinated? 

Infants and young children from six month to five years old. People 65 years of age and older. Pregnant women. People with certain health conditions or a weakened immune system. Close contacts of above mentioned individuals and household members of children younger than two years old.

When Should I Get the Flu Vaccine?

The exact timing and duration of flu seasons can vary, but influenza activity often begins to increase in October. Most of the time flu activity peaks between December and February, although activity can last as late as May. The best time for the flu vaccination is before the peak of flu season, which is before the end of October. However, flu vaccine is recommended throughout the flu season. 

Can the Flu Vaccine Give Me the Flu?

The flu vaccine does not cause the flu.

What are the Risks of a Vaccine Reaction?

Soreness, redness and swelling where the shot is given, fever, muscle aches and headaches can all happen after the influenza vaccine. There may be a very small increased risk of Guillain-Barré Syndrome (GBS) after the inactivated influenza vaccine (the flu shot). As with any medicine, there is a very remote chance of a vaccine causing a severe allergic reaction, other serious injury, or death.
