Influenza, commonly called the flu, is a contagious respiratory infection that can cause fever, cough, sore throat, body aches, fatigue, and other uncomfortable symptoms.

While many people recover without serious complications, influenza can be more dangerous for older adults and people with certain chronic health conditions. Annual flu vaccination remains an important part of preventive healthcare, and the Centers for Disease Control and Prevention recommends routine influenza vaccination for everyone age 6 months and older who does not have a medical reason to avoid vaccination. [1]

At Code Med Urgent Care in Alexandria, VA, flu vaccines are offered as part of patient-centered preventive care. For individuals living in Alexandria and nearby communities such as Annandale, Springfield, and Falls Church, understanding when to get a flu vaccine and who may benefit most can make seasonal health decisions easier. Vaccination does not guarantee that you will never get influenza, but it can help reduce the risk of influenza and its complications. [1,2]

Who should get a flu vaccine?

Annual influenza vaccination is recommended for most people age 6 months and older who do not have a contraindication, meaning a medical reason that makes a vaccine unsafe for them. Because influenza viruses change over time, seasonal vaccination is recommended rather than relying on a vaccine received in a previous year. [1]

Flu vaccination is particularly important for people who have a higher risk of developing serious complications from influenza, including:

- Adults age 65 and older

- People with certain chronic medical conditions

- People with weakened immune systems

- Pregnant individuals

- Young children

- People who live in nursing homes or other long-term care settings

- People who regularly spend time around individuals at higher risk for severe influenza

For older adults, vaccination is especially important because the immune system becomes less responsive with age. Research has found that enhanced influenza vaccines, including high-dose and adjuvanted vaccines, can provide greater protection against some influenza-related outcomes in adults age 65 and older. [2,3]

When is the best time to get a flu vaccine?

For most people, influenza vaccination is ideally given during September or October. However, vaccination can still be beneficial later in the season as long as influenza viruses are circulating and an appropriate vaccine is available. [1]

The timing can be especially important for older adults. The protection provided by vaccination can decrease over time, so vaccination too early may not always be ideal for people who are more vulnerable to influenza later in the season. The appropriate timing can depend on age, health status, local influenza activity, and the likelihood that someone may not be able to receive the vaccine later. [1]

It is also important to remember that the flu vaccine does not cause influenza. Injectable flu vaccines use inactivated virus or other vaccine technologies that cannot cause influenza infection. Some people may experience temporary effects such as soreness at the injection site, tiredness, headache, or a low-grade fever as the immune system responds to vaccination. [4]

How does the flu vaccine help protect against influenza?

The flu vaccine helps the body's immune system recognize influenza viruses. If a vaccinated person is later exposed to a virus covered by the seasonal vaccine, the immune system may be better prepared to respond.

Protection is not perfect because influenza viruses change from season to season, and the match between circulating viruses and vaccine strains can affect effectiveness. Even so, vaccination remains an important tool for reducing the risk of influenza and influenza-related illness. Research involving older adults has found evidence that influenza vaccination can reduce influenza-like illness and some serious outcomes, although effectiveness varies by season, vaccine, and patient population. [2,5]

Flu vaccination is also part of broader preventive care. Reducing influenza illness can be particularly valuable for older adults and people with underlying health conditions because influenza can contribute to complications such as pneumonia and can place additional stress on the heart and lungs. [5,6]

Are there special flu vaccine considerations for older adults and people with health conditions?

Yes. Age and overall health can influence which influenza vaccine is most appropriate.

For adults age 65 and older, the CDC's 2025-2026 recommendations preferentially identify high-dose inactivated, recombinant, or adjuvanted influenza vaccines when available. If one of these preferred options is not available, another age-appropriate influenza vaccine should be used rather than delaying vaccination. [1]

People with chronic medical conditions may also need individualized consideration. A patient's age, medical history, allergies, pregnancy status, immune system function, and previous reactions to vaccines can all be relevant when determining which vaccine is appropriate.

- Before receiving a flu vaccine, patients should tell their healthcare professional about:

- A previous severe allergic reaction to an influenza vaccine or one of its components

- A history of Guillain-Barré syndrome

- Current illness or significant health concerns

- Pregnancy or possible pregnancy

- Medications or medical conditions that affect the immune system

- Any questions or concerns about previous vaccinations

These factors do not necessarily mean that someone cannot receive a flu vaccine. They help healthcare professionals determine whether vaccination is appropriate and which vaccine may best fit the patient's circumstances. [1,4]
