Flu vaccines cannot cause the flu because they are made with inactive viruses or no viruses at all, states the CDC. Possible side effects of flu vaccinations are redness, tenderness and swelling at the injection site, muscle aches, and slight fever.

While it is not possible to get the flu from a flu vaccine, it is possible to get the flu even if the vaccine was administered, reports the CDC. Vaccinated individuals may get the flu if they were exposed to the virus prior to receiving the vaccination, or if they were exposed to the virus within two weeks after receiving the shot. The vaccination requires two weeks for immunity to develop.

Individuals who have been vaccinated against influenza may contract other respiratory illnesses with similar symptoms that may be mistaken for the flu, notes the CDC. The influenza vaccine does not protect against rhinoviruses, which are associated with the common cold.

It is possible to contract a flu virus even after receiving a vaccination if the form of the influenza virus is significantly different than the viruses the vaccination was designed to protect against, states the CDC.
