Vaccines to Prevent Pneumonia in Older Adults: A Guide for Family Caregivers

Pneumonia is a serious and common infection in older adults, especially for those living with dementia. The good news is that safe, effective vaccines can significantly reduce the risk. This article explains which vaccines are recommended, why they matter for your loved one, and exactly how to talk with their clinician to get them protected. You are not alone in navigating this—there are concrete steps you can take today.

Key points

  • Pneumonia is a leading cause of death in older adults with dementia, but vaccines can significantly reduce the risk.
  • The two key vaccines are the pneumococcal vaccine (pneumonia shot) and the annual flu vaccine.
  • The shingles vaccine (Shingrix) may also reduce dementia risk and is recommended for adults 50+.
  • Check your loved one's vaccine history and schedule a 'vaccine review' appointment with their clinician.
  • Vaccines are safe and covered by Medicare/Medicaid; mild side effects are normal and temporary.
  • Do not wait until your loved one is sick—plan ahead, especially before flu season.

Why Pneumonia Is a Major Risk for Older Adults with Dementia

Pneumonia is a leading cause of hospitalization and death in older adults, and the risk is even higher for people living with dementia. Research shows that individuals with dementia are more than twice as likely to die from pneumonia compared to those without dementia. This is partly because dementia can make it harder to clear the lungs of secretions, and because swallowing difficulties (dysphagia) often develop, leading to aspiration of food or liquid into the lungs—a common cause of pneumonia in this population. Additionally, as dementia progresses, mobility declines, which can weaken the immune system and make the body more vulnerable to infections.

Which Vaccines Are Recommended for Community-Acquired Pneumonia?

For older adults, the two key vaccines are the pneumococcal vaccine (which protects against the most common bacterial cause of pneumonia) and the annual flu vaccine (since influenza can lead to viral pneumonia). The pneumococcal vaccine is typically given as a single shot, but some people may need a second dose depending on their age and health conditions. The CDC recommends that all adults aged 65 and older receive the pneumococcal conjugate vaccine (PCV15 or PCV20) or the pneumococcal polysaccharide vaccine (PPSV23), depending on their vaccination history. The flu vaccine is recommended annually for everyone aged 6 months and older, and it is especially important for older adults with chronic conditions like heart disease, lung disease, or diabetes—all of which are common in people with dementia.

How Vaccines Help Prevent Pneumonia in People with Dementia

Vaccines work by training the immune system to recognize and fight off specific germs before they cause infection. For a person with dementia, preventing pneumonia is crucial because once an infection sets in, it can be harder to treat and can lead to rapid decline. Pneumonia in older adults with dementia often presents without the classic symptoms of fever or cough, making it easy to miss until it is advanced. By getting vaccinated, you are giving your loved one a strong layer of protection that can keep them out of the hospital and maintain their quality of life. Even if they do get pneumonia, being vaccinated can make the illness milder and shorter.

Step-by-step

  1. Gather your loved one's vaccine history — pneumococcal, flu, shingles, and COVID-19 — and any allergy or reaction notes, to share with the clinician before the appointment.

  2. Schedule a vaccine-review visit and ask about pneumococcal, flu, and shingles vaccines in one visit; pneumococcal and flu shots can often be given the same day.

  3. If your loved one is in a nursing home or assisted living, ask the facility's nursing staff about their on-site vaccine clinics and which pneumonia-related vaccines they offer.

  4. After vaccination, watch for common side effects like sore arm, mild fatigue, or low fever for a day or two; call the clinician if you notice trouble breathing or high fever.

  5. Record each vaccine your loved one receives — date and exact type — in a home record kept with their medical papers, to prevent unnecessary repeat doses at future visits.

What not to do

  • Do not assume a past pneumococcal shot still protects — some need a booster or a different type as people age; confirm with the clinician.

  • Do not skip the annual flu vaccine; influenza can lead to viral pneumonia, which is especially dangerous for people with dementia.

  • Do not wait until your loved one is sick to get vaccinated — vaccines take about two weeks to build full immunity, so plan before flu season.

  • Do not let fear of mild side effects prevent vaccination; the risk of severe pneumonia in someone with dementia far outweighs temporary discomfort.

  • Do not forget to ask about the shingles vaccine (Shingrix); it is recommended for adults 50+ and recent research suggests it may also lower dementia risk.

  • Do not assume vaccines eliminate all pneumonia risk — stay alert to symptoms like new cough, fever, or sudden confusion and seek care promptly.

Practical tools

  • Vaccine History Tracker

    Create a one-page document listing: date of birth, allergies, past vaccines (pneumococcal, flu, shingles, tetanus, COVID-19) and dates. Keep in a folder with medical records, or use MyChart if available.

  • Clinician Conversation Script

    Print these exact phrases: 'I am worried about pneumonia because my loved one has dementia. Which vaccines do you recommend to prevent pneumonia? Which pneumococcal vaccine is right — PCV15, PCV20, or PPSV23? Can we get pneumococcal and flu today? Should we also consider shingles vaccine for brain health?'

  • Vaccine Side Effect Log

    After vaccination, note date, vaccine type, and any symptoms (sore arm, mild fever, fatigue). Use a notebook or phone note to track what is normal and when to call the doctor.

  • Facility Vaccine Checklist

    If in a nursing home or assisted living, ask: 'What is your policy for vaccinating residents against pneumonia? Do you offer pneumococcal and flu vaccines on-site? Can I be present when they are given?' Write down the answers.

  • Reminder Calendar

    Set a yearly reminder in the fall for the flu vaccine. Also set a reminder to ask about the pneumococcal vaccine every 5 years (or as recommended).

Discuss with your clinician

Ask: 'Is my loved one a candidate for the pneumococcal vaccine if they have had a severe allergic reaction to a vaccine in the past?'

Ask: 'Can the pneumococcal and flu vaccines be given at the same visit? Are there any interactions with their current medications?'

Ask: 'If my loved one has had pneumonia before, do they still need the vaccine?'

Ask: 'Are there any reasons my loved one should NOT get the shingles vaccine, such as a weakened immune system or current illness?'

Ask: 'How long after the vaccine will my loved one be protected? When should we schedule the next dose if needed?'
