and that's just part of the bargain. ♪ i'm not getting through the pandemic just to end up with the flu. i asked for fluzone high-dose quadrivalent. it's the #1-used flu vaccine for people 65 and older. fluzone high-dose quadrivalent is the only vaccine approved by the fda for superior flu protection in adults 65+. i'm not letting my guard down. fluzone high-dose quadrivalent isn't for people who've had a severe allergic reaction to any flu vaccine or vaccine component, including eggs or egg products. tell your health care professional if you've ever experienced severe muscle weakness after receiving a flu shot. people with weakened immune systems, including those receiving therapies that suppress the immune system, may experience lower immune responses. vaccination may not protect everyone. side effects include pain, redness, and/or swelling where you got the shot, muscle ache, headache, and general discomfort. other side effects may occur.
