Yes, you have Shoulder Injury Related to Vaccine Administration, or SIRVA. According to those damaged, they believe the vaccination was given too high up on the arm and resulted in limited range of motion, pain, tingling, numbness, and weakness.
Subsequent MRIs performed on 69 percent of those complaining with symptoms revealed:
Fluid collection in the deep deltoid muscle or overlying tendons
Bursitis
Fluid greater than typically seen in the bursa
Tendonitis
Subchondral changes with severe tendonitis in one patient
The symptoms can last from months into years. Of those studied, less than one third experienced complete recovery.

Article to check out - Shock vaccine study reveals influenza vaccines only prevent the flu in 1.5 out of 100 adults (not 60% as you've been told).
Flu shots are given in the deltoid muscle. Muscle ache, redness and inflammation at the injection site is common. Tylenol taken at the time of the shot is best.
Abcesses at the site are rare and are related to unsterile technique. This is not your experiend. I don't think you have a malpractice case given that your shoulder issue has been long standing.
You would do well to take regular tylenol and ibuprofen (at least twice a day)for pain management. They can be taken together safely as they have different mechanisms of action and effect. Consult your doctor if you have a history of stomach issues like acid reflux or ulcers before taking daily ibuprofen. You may need a stronger anti-inlammatory like toradol. Continue full range of motion excersises to prevent further pain and stiffness. I hope this helps. Take care :o)
