Your vaccine at work: The flu vaccine is designed to create an immune response to flu components. The pain felt is associated by the cytokines (proteins serving as a communications device) produced by local and immune cells that can cause white blood cell localization and inflammation . This is normal and part of the process that is meant to protect you form the flu itself

Somewhat: About 5% of individuals who receive the flu vaccine will experience 3 or 4 days of a mild flu-like illness after the injection.
