Can I get the flu even though I got a flu shot?
Yes. The ability of the flu vaccine to protect a person depends on the age and health status of the person getting vaccinated, and the similarity or “match” between the virus strains in the vaccine and those circulating in the community.
What are common side effects from the flu shot?
You can expect soreness, redness, and/or swelling from the shot, headache, fever, nausea, and muscle aches. These symptoms should be mild and go away in 1-2 days.
