Understanding Vaccines for Older Adults

Vaccines are medical treatments that teach your immune system to recognize and fight specific diseases. As people age, the immune system naturally becomes weaker, making older adults more vulnerable to serious illnesses from diseases like influenza, pneumonia, and shingles. Vaccines work by introducing a small, harmless piece of a disease—or instructions for your body to make that piece—so your immune system can learn to defend against the real disease if you encounter it later.

For seniors, vaccines serve an important role in disease prevention. Unlike younger people whose immune systems are stronger, older adults often experience more severe complications from common infections. For example, the flu can lead to pneumonia, hospitalization, or death in people over 65. Pneumococcal disease can cause blood infections and meningitis. Shingles can cause long-lasting nerve pain that affects quality of life. Vaccines reduce these risks significantly.

There are several types of vaccines available, each designed to protect against different diseases. Some vaccines use weakened forms of viruses or bacteria. Others use inactivated (dead) versions. Newer vaccines use messenger RNA (mRNA) technology, which teaches your cells to produce a protein that triggers immune response. Each type works differently, but all aim to create protection without causing the actual disease.

The CDC (Centers for Disease Control and Prevention) recommends specific vaccines for people 65 and older based on research showing which diseases pose the greatest risk. These recommendations change as new research emerges and as disease patterns shift. Understanding what vaccines are available and why they matter helps you and your doctor make informed decisions about your health.

Practical takeaway: Vaccines are tools that strengthen your immune system's ability to fight serious diseases. Learning about which vaccines are recommended for your age group provides information to discuss with your healthcare provider.

Vaccines Recommended for People 65 and Older

The CDC maintains a list of vaccines recommended for older adults. These recommendations are based on which diseases pose serious health risks for seniors and where gaps in protection may exist from vaccines received earlier in life. The main vaccines discussed for this age group include influenza (flu), pneumococcal disease, shingles, tetanus/diphtheria/pertussis, COVID-19, and RSV (respiratory syncytial virus).

The seasonal flu vaccine is recommended every year for all adults 65 and older. Influenza can be particularly dangerous for older adults—about 80% of flu deaths occur in people 65 and older, according to CDC data. There are several formulations of the flu vaccine available, including standard-dose versions and high-dose versions specifically designed for older adults. The high-dose flu vaccine contains four times more antigen (the component that triggers immune response) than the standard vaccine. Research suggests the high-dose version may provide better protection for seniors.

Pneumococcal vaccines protect against pneumococcal disease, which can cause pneumonia, blood infections, and meningitis. The vaccination approach for pneumococcal disease changed in 2024, with new CDC recommendations shifting from the previous strategy. Currently, the recommendation is to receive a single dose of the newer pneumococcal vaccine (PCV20) for most adults 65 and older who have not previously received pneumococcal vaccines. The specific pneumococcal vaccine plan may vary based on your vaccination history and health conditions.

Shingles vaccination is recommended for all adults 65 and older, regardless of whether they remember having chickenpox. The shingles vaccine (Shingrix) requires two doses given 2 to 6 months apart. Shingles causes painful rashes that can last for weeks or months, and some people experience persistent pain long after the rash heals. The vaccine is highly effective at preventing shingles and the complications that can follow.

COVID-19 vaccination continues to be recommended for older adults. While initial vaccination series are important, updated formulations of COVID-19 vaccines are released periodically to match circulating variants. The frequency of COVID-19 boosters may change based on new recommendations and your individual risk factors.

RSV (respiratory syncytial virus) vaccination became available for older adults in 2023. RSV causes respiratory illness that can be severe in seniors, potentially leading to hospitalization. A single dose of the RSV vaccine is recommended for adults 60 and older in certain situations or for all adults 75 and older.

Practical takeaway: Multiple vaccines are available for older adults to prevent serious diseases. Your healthcare provider can review which vaccines fit your personal health situation and vaccination history.

How to Discuss Vaccines With Your Healthcare Provider

Making decisions about vaccines is a conversation between you and your healthcare team. Your doctor, nurse practitioner, or physician assistant knows your complete medical history, existing health conditions, medications, and previous vaccine reactions. This information is essential for determining which vaccines are appropriate for you.

Before your appointment, gather information about your vaccination history. If possible, find records showing which vaccines you received and when. This might be in old immunization cards, previous doctor's records, or health department records. If you cannot locate records, your healthcare provider can help reconstruct your history or, in some cases, order blood tests to determine immunity status. Knowing your history prevents unnecessary duplicate vaccines and identifies gaps in protection.

Write down any questions or concerns you have about vaccines before your appointment. Common questions include: Which vaccines do you recommend for me? Why is this vaccine important for someone my age? Are there any reasons this vaccine might not be suitable for me? What are the possible side effects? How long does protection last? Where can I receive the vaccine? What should I do if I have a reaction? Having these ready ensures you cover important topics during your visit.

Be open about any previous vaccine reactions you have experienced. Reactions range from mild (soreness at injection site, low fever) to serious (severe allergic reactions). If you had a serious reaction to a vaccine component in the past, your healthcare provider needs this information. However, mild reactions typically do not prevent future vaccinations. Your provider can discuss strategies to minimize discomfort, such as taking pain relievers before or after vaccination.

Discuss your health conditions and medications with your provider. Certain conditions or medications might affect vaccine timing or choice. For example, if you take blood thinners, your provider might recommend injection technique to minimize bruising. If you have a weakened immune system from certain medications or conditions, some vaccines might need to be scheduled differently. These conversations help ensure vaccines are given safely and effectively.

Ask your provider about the timing of vaccines. Some vaccines can be given at the same visit, while others need spacing between them. Your provider can create a vaccine schedule that fits your needs and makes sense for your healthcare visits.

Practical takeaway: Schedule a conversation with your healthcare provider about your vaccine needs. Bring your vaccination history, write down your questions, and discuss any health conditions or concerns that might affect your vaccine decisions.

Where to Receive Vaccines as a Senior

Vaccines for older adults are available through several locations, giving you options based on convenience and preference. Your primary care doctor's office is often a good starting point. Your regular physician knows your health history and can recommend appropriate vaccines, administer them, and monitor for any reactions. If you see a primary care provider regularly, scheduling vaccines during a routine visit adds little extra time.

Community health centers and federally qualified health centers (FQHCs) provide vaccines to people regardless of insurance status or ability to pay. These centers often have flexible hours and may offer vaccines on a walk-in basis or by appointment. Many have multilingual staff and can work with people with different healthcare needs.

Pharmacies with vaccine clinics represent another common option. Major pharmacy chains and independent pharmacies often employ trained pharmacists who can administer vaccines. Pharmacies may offer extended hours, including evenings and weekends, and many do not require appointments. Pharmacists can answer questions about vaccines, though complex medical discussions might be better suited for your primary care provider.

Health departments in your county or state frequently offer vaccine clinics, particularly for influenza and pneumococcal vaccines. Health department clinics may charge reduced fees or no fee, depending on your income and insurance status. They often hold seasonal flu clinics in the fall and can provide information about other recommended vaccines.

Senior centers, assisted living facilities, and nursing homes often host vaccine clinics for residents and sometimes for community members. These settings are convenient if you live in or frequently visit these locations. Some facilities bring vaccine providers to residents who cannot travel to other locations.
