Every single Flu-vaccine has a high probability of showing flu-like symptoms. These are from a medicinal standpoint nothing compared to the seriousness of the real flu.
Even MMR-Vaccines are expected to cause a harmless form of "vaccine-measles", which can show up as mild rash, low fever, etc. Again, no these are not to be concerned about.
These vaccination-associated symptoms are widely harmless and there is no reason to mingle them with ongoing side-effects caused by vaccinations.
