Influenza vaccine: Flu shot side effects may include: slight swelling, redness or pain at vaccination site. If headache, nausea, fever or muscular pain occur they usually resolve within one to two days. You won't get the flu from a flu shot because the virus either contains inactivated virus or doesn't have virus particles in it. Severe side effects are rare. Don't know which nodes were swollen. Might not be due
