What to Avoid After Your Flu Shot

After you receive an influenza vaccine, there are some precautions that you should consider to ensure your safety and the full effect of your flu vaccine.

The flu shot may cause dizziness or fainting, side effects which usually don’t last longer than a day or two. To be on the safe side, don’t stand up immediately after getting your flu shot; remain seated for a while.

Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with circulating influenza viruses. During this two-week period, try to stay home as much as possible and avoid crowded places to lower your risk of getting infected with flu and other respiratory infections.

Like any vaccine, the flu vaccine can cause side effects. These are generally mild and go away on their own within a few days. Common side effects from the flu shot include:

  • soreness,
  • redness, and/or swelling from the shot,
  • headache,
  • fever,
  • nausea, and
  • muscle aches.

Practicing bad health habits is the worst thing that you can do while your body is recuperating from the effects of your flu shot. Don’t skimp on rest and sleep, as well as on fluids and nutritious food. Avoid stressful situations. Don’t forget to engage in physical activity, as long as it’s not too strenuous. Doing these healthy practices can help boost your immunity and speed up your recuperation.

Consult your doctor for more information on what to avoid after your flu shot.
