You should get the flu vaccine every year, as the flu virus changes and the vaccine is updated annually to provide the best protection.

Common side effects include soreness at the injection site, mild fever, and muscle aches. These side effects are generally mild and temporary.

No, you cannot get the flu from the flu vaccine. The vaccine contains inactivated viruses or a single protein from the flu virus, which cannot cause illness.

Once you receive your flu shot, it takes 2 weeks for your body to develop antibodies that provide protection. It’s important to remember that during this period, you’re still vulnerable to becoming ill with the flu. During that time, you should be extra careful to:

• practice good hygiene
• avoid touching your nose or mouth whenever possible
• avoid crowds if flu is circulating in your community
