If you are having a severe reaction, the CDC said you may experience high fever or behavior changes, difficulty breathing, hoarseness or wheezing, swelling around the eyes or lips, hives, paleness, weakness, a fast heart beat or dizziness. The CDC recommends seeking medical attention immediately if you spot any of the above symptoms.
The Vaccine Adverse Event Reporting System (VAERS) is a national vaccine safety surveillance program co-sponsored by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA). VAERS is a post-marketing safety surveillance program, collecting information about adverse events (possible side effects) that occur after the administration of vaccines licensed for use in the United States. Their site is: vaers.hhs.gov

Also, for those in the USA, you can find out where to get a flu shot via the www.flushotsusa.com website and register your children depending where you live.

Note: As of 23 August, the WHO (World Health Organization) estimated over 209438 cases and at least 2185 deaths. (Given that countries are no longer required to test and report individual cases, the number of cases reported actually understates the real number of cases.)
