Adults over 65 should keep current with seven key vaccines that protect against serious illnesses that are both more common and more severe in older age: the flu, COVID-19, pneumococcal disease, shingles, respiratory syncytial virus (RSV), hepatitis B, and tetanus. These vaccinations aren’t optional medical extras—they directly affect whether you can stay independent at home, avoid hospitalization, and maintain quality of life as you age. Consider someone like Margaret, 72, who thought she didn’t need an updated flu shot because she’d had one years ago.
During the 2025-2026 flu season, which is predicted to be one of the most severe in 25 years, she contracted influenza and spent two weeks in the hospital, which set back her physical recovery and independence for months. Your immune system changes as you age, making these vaccines more important, not less. The CDC’s recommendations have evolved specifically because older adults face higher risks from preventable infections. The good news is that Medicare covers the cost of all six major vaccines without cost-sharing for eligible seniors.

Which Vaccines Are Most Critical for Adults Over 65?
The foundation of adult vaccination in older age rests on three vaccines: the flu shot, COVID-19, and pneumococcal protection. The CDC specifically recommends that all adults aged 65 and older receive a higher-dose flu vaccine or adjuvanted flu vaccine—not the standard flu shot—because your body’s response to the regular version is weaker. This distinction matters: the higher-dose option is designed to trigger a stronger immune response in older adults. For the 2025-2026 season, there’s an additional option on the horizon. The FDA is reviewing Moderna’s new mRNA flu vaccine (mFlusiva), with a decision expected by August 5, 2026. This represents a shift toward the same mRNA technology that’s proven effective for COVID-19, adapted for influenza protection.
COVID-19 protection remains essential even five years into the pandemic. The CDC recommends that all adults 65 and older receive two doses of the updated 2025-2026 mRNA-based COVID-19 vaccine. You have options: Pfizer’s Cominarty, Moderna’s Spikevax or mNexspike, or Novavax’s Nuvaxovid. These vaccines continue to significantly reduce the risk of severe illness, hospitalization, and death. For pneumococcal disease, the CDC now offers flexibility. You can choose between a single dose of either PCV20 or the newer PCV21, or you can receive PCV15 followed later by PPSV23. This choice exists because PCV21 was added to vaccination recommendations in October 2024, giving adults more options based on their medical history.
Protection Against Shingles and RSV—Vaccines That Go Beyond Preventing Illness
Shingles represents a particularly compelling reason to stay on top of your vaccination schedule. If you had chickenpox as a child (and most adults over 65 did), the virus remains dormant in your nerve tissues. Shingrix, the shingles vaccine, prevents reactivation of that virus. The protection rates are remarkable: in adults over 70, Shingrix is 91 percent effective at preventing shingles entirely and 89 percent effective at preventing postherpetic neuralgia, the chronic pain condition that can linger for years after shingles rash heals. The CDC recommends two doses separated by 2 to 6 months for all adults 50 and older, with no maximum age limit. Protection lasts at least 7 years, with data showing continued high protection beyond a decade. Even if you received Zostavax, the older shingles vaccine, you should still get Shingrix.
RSV (respiratory syncytial virus) is less well-known than flu or COVID but equally serious in older adults. This virus causes respiratory illness that can lead to severe pneumonia, hospitalization, and even death in seniors. The CDC updated its RSV vaccine recommendation in June 2024 and now recommends that all adults aged 75 and older receive one dose of RSV vaccine. Adults aged 60 to 74 should also receive it if they have chronic lung or heart disease or live in nursing homes. Three RSV vaccines are now available: GSK’s Arexvy, Moderna’s mResvia, and Pfizer’s Abrysvo. A critical limitation to understand: unlike some vaccines, RSV protection is based on receiving one dose, so you need to discuss with your doctor which vaccine fits your situation best. Medicare Part D now covers RSV vaccines per ACIP recommendations.
Hepatitis B and Tetanus Protection—Why These Vaccines Still Matter in Your 60s and Beyond
Hepatitis B vaccination is now recommended as routine immunization for all adults 65 and older, regardless of prior risk. This represents a shift in thinking, as hepatitis B was historically targeted mainly at those with specific exposures. The reason for this broader recommendation is that vulnerability to hepatitis B increases with age, and older adults may have been exposed without knowing it. Even if you had hepatitis B vaccination decades ago, an additional dose now can provide protection or reinforce existing immunity. Tetanus, diphtheria, and pertussis protection requires maintenance, not a one-time vaccination.
The CDC recommends a Tdap or Td booster every 10 years throughout your life. If you haven’t had one since you were in your 50s, this isn’t a vaccine to skip. Tetanus is rare in the United States specifically because of vaccination, but when it does occur, it’s a medical emergency. An infection from a puncture wound—something that could happen from stepping on a rusty nail while gardening or from a minor injury at home—becomes far more serious without current protection. The vaccine is quick, the protection is essential, and it’s covered by Medicare.
Making Vaccination Practical—Cost, Timing, and How to Stay Organized
Medicare fully covers six vaccines for adults 65 and older: flu, pneumococcal, shingles, RSV, COVID-19, and hepatitis B. Vaccine administration is also covered with no cost-sharing. If you have supplemental insurance or Medicaid, coverage is already built in. This financial barrier is removed, which means if cost has been a hesitation, that reason no longer applies. The question then becomes logistical: how do you organize getting multiple vaccines at different times? A practical approach is to schedule your flu and COVID-19 vaccines together each fall when new formulations become available.
Shingrix requires two doses 2 to 6 months apart, so you might schedule the first dose in fall and the second in spring. RSV is a single dose, which you can coordinate with your pneumococcal vaccination if you haven’t had recent pneumococcal protection. Talk to your primary care doctor about a vaccination plan that fits your schedule, or work with your pharmacist—many pharmacies can administer multiple vaccines in one visit. One tradeoff: spacing between some vaccines matters. Your doctor or pharmacist can advise you on whether you can receive multiple vaccines at once or need to space them apart, which usually takes just a few weeks.
Addressing Vaccine Side Effects and When to Be Cautious
Vaccine side effects in older adults are typically mild and resolve within a few days. Common reactions include arm soreness, low-grade fever, fatigue, or temporary aches. For Shingrix specifically, arm pain and soreness are common after the injection, and some people experience brief fatigue after the second dose. These reactions are signs your immune system is responding, not warnings that the vaccine isn’t safe. However, there are situations where you need to discuss vaccination more carefully with your doctor. If you’ve had a severe allergic reaction to any component of a specific vaccine, you need to know which vaccines are safe for you.
If you have a bleeding disorder or take blood thinners, your doctor needs to know before you receive an injection. If you’ve had Guillain-Barré syndrome (a rare paralysis condition), discuss RSV vaccination specifically with your healthcare provider first. A common misconception is that older adults shouldn’t be vaccinated if they’re already dealing with chronic illness like heart disease or diabetes. The opposite is true: these conditions make vaccination even more important because they put you at higher risk of severe complications from preventable infections. Your immune response might be somewhat lower than in a younger person, which is exactly why the CDC recommends higher-dose flu vaccines for older adults—to account for this reduced response. Don’t skip vaccination because of chronic illness; instead, make sure your doctor reviews the timing and approach with your specific conditions in mind.
Looking Ahead—New Vaccines and Evolving Recommendations
The landscape of vaccines for older adults is changing. The FDA decision on Moderna’s mRNA flu vaccine by August 5, 2026, could mean better flu protection is coming. mRNA technology has proven effective for COVID-19, and adapting it for influenza represents a significant step forward in vaccine development. PCV21, approved in October 2024, gives older adults another effective option for pneumococcal protection.
These aren’t dramatic overhauls but incremental improvements that reflect decades of vaccine research focused on aging populations. Staying current doesn’t mean getting vaccinated every year for every vaccine. It means maintaining your protection through recommended boosters and new vaccines as they’re added to the recommended schedule. Your doctor or pharmacist can review your vaccination history and tell you what you need. Some vaccines require boosters every 10 years; others, like annual flu vaccines, need yearly updates because new flu strains emerge each season.
Taking Action—Your Vaccination Plan for the Year Ahead
The best vaccination plan is the one you’ll actually follow. Whether you’re coordinating with your primary care doctor or visiting a pharmacy clinic, the steps are straightforward. First, review what you’ve had. Do you know when you last received a tetanus booster? Have you ever had Shingrix? Have you received the updated 2025-2026 COVID-19 vaccine? If you’re uncertain, bring any vaccination records you have to your appointment, or your healthcare provider can check their records. Second, discuss which vaccines you need and any questions about side effects or interactions with medications you take.
Third, schedule them in a way that fits your life—whether that’s all at once or spaced over several appointments. Finally, mark your calendar for future boosters like the annual flu vaccine and any repeat doses, like the second dose of Shingrix. The vaccines recommended for older adults exist because decades of research have proven they prevent serious illness and death. They’re not new or experimental; most have been in use for years and have been specifically updated for older adults’ changing immune systems. Staying current with vaccination is one of the most straightforward ways to protect your independence, avoid hospitalization, and maintain your quality of life as you age.
Conclusion
Adults over 65 should maintain current protection against seven key vaccines: influenza (with higher-dose or adjuvanted options), COVID-19, pneumococcal disease, shingles, RSV, hepatitis B, and tetanus. Medicare covers all of these vaccines without cost-sharing, removing financial barriers to protection. The time to schedule these vaccines is now—before flu season intensifies and while new options like Moderna’s mRNA flu vaccine are emerging.
Don’t delay vaccine appointments thinking you’re too healthy or that you don’t need them. The opposite is true: your changing immune system as you age makes these vaccines more important, not less. Talk to your doctor or pharmacist this week about which vaccines you need and schedule them into your calendar. Staying current with vaccination is how you protect your ability to remain independent, care for yourself at home, and avoid the hospitalizations that can derail your quality of life.
