For the last four years, doctors, pharmacies, and medical clinics have all offered seniors a higher dose version of the annual flu shot. At the time that the vaccine was released the science was lacking but the hope from medical professionals was that the higher dosage would provide better protection for the elderly. Now, the first studies on this version of the flu shot are in, and the results are looking positive.
Higher Dose Flu Shot
The annual flu shot for seniors, known as Fluzone High-Dose, contains up to four times the amount of antigen found in the typical flu shot. Antigens are chemicals within the shot that stimulate the immune system. Previous research has shown that the increased antigens in the Fluzone produced a greater antibody reaction in seniors. This is significant because as the body ages the immune system becomes less effective.
