Flu Prevention for Seniors and When to Get the Flu Shot

Every year, the flu season can be a dangerous time for seniors. A change to the immune system or underlying health conditions puts seniors at risk for developing more severe cases of influenza, leading to complications or even death.

High-Dose Vaccines

Mithil Choksey MD, medical director for the Division of Geriatrics at Bridgeport Hospital, recommends patients of all ages get a flu shot and patients 65 and older should consider a high-dose flu vaccine.

“Our geriatric patients have a reduced ability to mount a strong response against the influenza virus and other infections due to age-related changes in the immune system,” said Dr. Choksey. “The high dose quadrivalent vaccine contains four times the antigen as the standard dose flu vaccines which helps generate a more robust immune response in the elderly.”

Caregivers should also get their flu shot as soon as possible. Talk to your doctor before getting the shot if you have a known allergy to the shot, if you’re acutely sick or immunosuppressed.

Flu Symptoms in Seniors

Classic flu symptoms include fever, chills and muscle pains. However older patients are less likely to present with these symptoms. Geriatric patients present with more nonspecific signs such as weakness, dizziness, confusion, loss of appetite and the exacerbation of underlying chronic diseases such as heart failure.

If an older patient has a fever, they should call their doctor right away.

“The greatest clinical benefit of antivirals is noted if treatment is started within 48 hours of symptoms, so I would encourage our seniors not to delay getting tested and call their provider promptly if they feel unwell during this season,” said Dr. Choksey.

If seniors are not eating or drinking, experiencing shortness of breath or experience a change in mental status, they should seek emergency help.

Flu Prevention

In addition to getting the flu shot, Dr. Choksey stresses the importance of proper prevention measures. Wash hands for at least 20 seconds with soap and water or use a hand sanitizer with at least 60% alcohol after being in public places during flu season. Maintain a safe distance from others who are not feeling well and stay home if you get sick. Studies have also shown wearing masks especially in crowded or enclosed spaces can help prevent the spread of respiratory illnesses.

Just as important as avoiding illness is living a healthy lifestyle. Seniors can help boost their immune response by staying hydrated, getting regular exercise and managing stress.
