Adverse Effects of Influenza Vaccine
ForIIV,adverse effects are usually limited to mild pain at the injection site. Fever, myalgia, and other systemic effects are relatively uncommon; however, people who have been vaccinated may mistakenly think that the vaccine is causing influenza. Such reactions do not contraindicate future vaccination, which should be encouraged. Multidose vials contain thimerosal, a mercury-based preservative. Public concerns about a possible Thimerosal and Autism have proved unfounded; however single-dose vials, which are thimerosal-free, are available. ForLAIV,adverse effects are mild; rhinorrhea is the most common, and mild wheezing may occur.
