Influenza (Flu Shot) Vaccine Injuries:
Flu shot side effects can include acute thrombocytopenic purpura, Guillain-Barré Syndrome, and tranverse myelitis.
The influenza vaccine attempts to protect against the flu virus. However, the virus changes every year, making it difficult to produce an effective vaccine each year. Some studies show the effectiveness of the vaccine to be very low, perhaps lower than 31%. It has been reported as low as a 9% efficacy for seniors over the age of 65 by the Centers for Disease Control: Interim Adjusted Estimates of Seasonal Influenza Vaccine Effectiveness—United States, February 2013. MMWR Feb. 22, 2013; 62:119-23.
