Sumary of Feeling Sick After the Flu Shot? Doctors Explains Why – and What To Do:
- The flu vaccine developed each year is the best estimate for the flu strains that are around, and if you were exposed to a different strain, you would not be protected, Carolyn Kaloostian, MD, MPH, a clinical assistant professor of family medicine at the University of California Keck School of Medicine.
- You should speak with your healthcare provider if youve had any allergic reactions in the past to medications or certain foods, including an egg allergy (the CDC does list some egg-free options for the flu shot), or have Guillain-Barré syndrome (GBS) (a rare immune system disorder).
- People can also get sick from other viruses around the moment when they get the flu shot, Michael Ison, MD, a professor of infectious diseases at Northwestern University Feinberg School of Medicine and a practicing physician at Northwestern Medicine, told POPSUGAR.
- The CDC reports that severe reactions to the flu shot are very rare.
