Flu Vaccines for Seniors
As our body ages, so does our immune system. That is why there are specially formulated vaccines available for individuals who are 65 years and older.
These vaccines are designed to induce a greater immune response so that the body produces enough antibodies to protect the recipient.
One type of flu vaccine specifically designed for seniors is the Fluzone High-Dose vaccine, which prompts the body with four times the number of viral particles contained in other vaccines. The other vaccine specifically designed for seniors, Fluad, contains a compound called an adjuvant, which induces the immune system to react more forcefully to the injection. Both of these vaccines can be used in adults age 65 years and older.
One
study on the high-dose flu vaccine found that adults age 65 years and older had 24 percent fewer influenza infections as compared to those who received a standard flu vaccine. One
study on the adjuvanted flu vaccine found it was 63 percent more effective than regular dose unadjuvanted flu shots. While the increased amount of protection may vary, experts agree that individuals 65 years of age and older should consider getting a flu vaccine specifically designed for seniors each season. Talk to your trusted healthcare professional about which one may be right for you.
