The swine flu vaccination has a few side effects but it is not as bad as the symptoms of swine flu itself. You can safely inject yourself without any problem. The main side effects of the vaccine are as follows:
• Fainting and headache
• Fatigue for several days after the vaccination
• Medium to high temperature
• Aches in muscle and nausea
• Redness, tenderness and general soreness near the injection area
The side effects can vary from person to person and there is no universal guarantee that it will happen. It might be stronger in children than in adults.
