Flu Vaccine for Seniors in Peoria: What You Need to Know

Written by Vista del Rio | Jul 14, 2025 4:00:00 AM

Are you prepared for flu season in Peoria, Arizona?

Older adults who catch the flu may experience such severe illnesses as pneumonia. Seniors are more susceptible to flu-related complications due to natural declines in immune function, as well as pre-existing health conditions.

Preventative measures like a flu vaccine for seniors, antiviral treatment, and good hygiene can reduce the risk of related illnesses. This article aims to provide seniors in Peoria with the latest information about senior immunizations in AZ and flu prevention tips.

Why Is the Flu More Serious for Older Adults?

Immune systems naturally weaken with age; this process is called immunosenescence. Seniors are more likely to struggle with viruses, including influenza. The flu can be especially strong, leading to more severe and prolonged illness.

Older adults who live with chronic health conditions are at a higher risk. Conditions include:

  • Heart disease
  • Lung disease (like COPD or asthma)
  • Diabetes
  • Kidney disease

The flu can exacerbate existing conditions, leading to more complications. For example, the flu could trigger a heart attack in a senior with heart disease. Seniors with diabetes can experience a spike in blood sugar.

Viral and bacterial pneumonia can also develop in seniors during the flu. A severe flu infection may necessitate hospitalization for monitoring and treatment.

Symptoms of the Flu in Older Adults

Seniors' families and caretakers should always be on the lookout for symptoms during flu season. Typical flu symptoms include:

  • Fever
  • Cough
  • Muscle aches

However, seniors may experience additional subtle or atypical symptoms.

Atypical symptoms to watch include confusion or disorientation. These signs may indicate an infection, prompting immediate medical attention.

Dizziness is an atypical symptom that also increases the risk of falls. Meanwhile, increased fatigue or muscle weakness may go beyond typical tiredness during the flu. Severe exhaustion is another symptom to watch.

Watch for a concerning loss of appetite.This can increase dehydration and malnutrition if not addressed quickly.

It's important to note that seniors may not always exhibit a fever during flu season. Low-grade fevers are also common. Therefore, it's important to pay attention to all other symptoms.

Preventing and Treating Flu in Older Adults

Start by staying up-to-date with all seasonal vaccines for seniors.

The annual flu vaccination is the most effective way to prevent the flu. It also reduces the risk of severe complications in seniors. Vaccinations help seniors build stronger immunity.

Antiviral medications are available if seniors do contract the flu. Talk to a doctor immediately. These medications should be recommended within 48 hours of initial symptoms.

Seniors need plenty of rest and hydration during flu recovery.

Talk to a doctor about Over-the-counter (OTC) medications for managing:

  • Fever
  • Aches
  • Cough

Good hygiene practices can help prevent the spread of the flu virus. Frequent handwashing with soap and water is a must. Seniors and families should wash their hands for at least 20 seconds after coughing or sneezing.

What People Should Know About The Flu Vaccine for Seniors

For better protection, the Centers for Disease Control and Prevention (CDC) and the Advisory Committee on Immunization Practices (ACIP) recommend higher-dose (or adjuvanted) flu vaccines for seniors.

Fluzone High-Dose Quadrivalent contains four times the amount of antigen of a standard flu vaccine. A Flublok Quadrivalent vaccine contains three times the antigen of a standard vaccination dose. Fluad Quadrivalent vaccines contain an adjuvant that strengthens immune responses.

The best time for seniors in Peoria, AZ, to receive the flu vaccine is between September and October. This time window offers optimal protection during peak flu season. The peak often runs from late fall through early spring.

Vaccinating too early might result in decreased protection later in the season, as vaccine-induced immunity can diminish over time.

Flu vaccination can reduce the risk of cardiovascular events, minimizing the likelihood of hospitalization for seniors with heart conditions. Seniors can take additional vaccines like pneumococcal vaccinations to protect against complications from pneumonia, a secondary infection linked to the flu.

What Seniors Should Do After a Flu Vaccine

Seniors need time to build immunity after receiving a flu shot.

Start with plenty of rest and hydrating fluids and foods. Resting helps seniors develop antibodies. It's important for seniors to stay as hydrated as possible in case mild fevers or body aches occur post-vaccination.

Flu shot injection site pain isn't uncommon. Seniors may experience:

  • Soreness
  • Redness
  • Swelling

Apply a cool, wet compress or ice pack to reduce pain or swelling in injection sites. Gentle arm movements can also prevent stiffness and soreness in seniors. OTC pain relievers are also available; it's important to strictly follow dosage instructions and consider any other senior medications.

Seniors should avoid any strenuous activity for at least two days after receiving a vaccination. Intense exercise and heavy lifting should be avoided. Avoid any activities that can worsen soreness or fatigue in seniors.

It's completely normal for vaccine recipients (of all ages) to experience some mild side effects. These reactions are often the immune system's response to the vaccine. Common side effects may include:

  • Soreness
  • Redness
  • Swelling (at the flu shot site)
  • Mild fatigue
  • Body aches
  • A low-grade fever

Post-vaccination side effects are usually mild and resolve within a couple of days. However, seek medical assistance if these severe symptoms appear

  • Difficulty breathing
  • Hives
  • Persistent high fever

Remember, the flu shot takes time to work!

It takes roughly two weeks after receiving a vaccination for a flu shot to provide full protection against the flu, according to Health. During this time, the body is building valuable antibodies.

Seniors and caretakers should still practice good hygiene protocols like frequent handwashing and social distancing to minimize the risk of infection before the vaccine becomes fully effective.
