Well the flu vaccine protects you from strains of the flu, but not common viral infections or bacterial like strep and the common cold.

Remember that quite often you get symptoms like ear stuffiness, sore throat, congestion, even bad coughs with the common cold if your immune systom is low enough (i am fighting it now)

even if you add fever to all these symptoms you most likely have a bad viral infection or possible strep. If it continues see a doctor.

If you have ever really had the true flu, let me tell you you would know it. Your body is so weak it feels as if you had been run over. You are plagued with fever and actually most often you do not actually have "cold" symptoms! All that, and you would be in bed for about 3 weeks, literally.

I hope you feel better!

For future reference, if you get any symptoms at all after receiving a vaccine, it is not from the vaccine, that is not a live virus. Chances are however as your immune system was adjusting itself you came in contact with a common virus, never would it be longer that a week or so after if it had anything whatsoever to do with your vaccine.

I've read that garlic is very good against flu cold and many ailments.
It works like a natural antibiotic! So eat garlic!
