The vaccines that matter most after 50
Your immune system changes as you age, which means the infections that barely slow you down at 30 can land you in the hospital at 70. Four vaccines have the strongest evidence behind them for older adults: flu, RSV, pneumonia, and COVID-19. Your doctor can tell you which ones fit your health history, but most people over 65 need all four — and the timing matters, because some have to be spaced weeks or months apart.
The good news is that Medicare Part B covers all of them at no cost to you if you have Original Medicare, and most Medicare Advantage plans cover them the same way. If you don't have Medicare, your insurance plan almost certainly covers them too, though you may have a copay. The real work is keeping track of which ones you've had and when the next dose is due.
Key Takeaways
- Flu, RSV, pneumonia, and COVID-19 vaccines are the four main ones recommended for people over 65, and Medicare covers all of them with no copay.
- Pneumonia vaccines now require two shots given at least one year apart, so if you had one years ago, you likely need a second one now.
- RSV vaccine is newer and given once; it became available in 2023 and is recommended for all adults 60 and older.
- Flu and COVID boosters are annual or periodic, depending on your age and health, so you'll need to plan for them each year.
- Your doctor or pharmacist can review your vaccine record and tell you which shots you're due for at your next visit.
Flu vaccine: annual protection
The flu vaccine is the one you get every year, ideally in September or October before flu season peaks. It comes in several forms — a standard shot, a high-dose version for people over 65, and a recombinant version — and your doctor can recommend which one fits you best. The high-dose and recombinant versions tend to produce a stronger immune response in older adults, which is why they're often preferred.
You can get the flu shot at your doctor's office, a pharmacy, a health department clinic, or many community centers. It takes five minutes and costs nothing if you have Medicare or most private insurance. The vaccine changes each year because the flu virus mutates, so even if you got one last year, you need a new one this year.
Pneumonia vaccines: now a two-dose series
Pneumonia vaccine recommendations changed in 2024, and if you haven't had a pneumonia shot in several years, your plan has likely shifted. The current guidance calls for two vaccines: Pneumococcal Conjugate Vaccine (PCV20) or a combination of PCV15 and PPSV23. If you've never had a pneumonia vaccine, you start with PCV20 as a single shot, and you're done. If you had PPSV23 years ago, you now need PCV20 at least one year after that old shot.
The spacing matters because your immune system needs time to respond. If you had PPSV23 more than a year ago, you can get PCV20 now. If it's been less than a year, wait until the year mark has passed. Your doctor's office can look at your records and tell you exactly when you're due.
The reason for the change is that PCV20 protects against more strains of pneumococcus than the older vaccines did, and studies show it works better in older adults. If you're unsure what you've had, ask your doctor to check your vaccine record or call your previous doctor's office — they keep these records for years.
RSV vaccine: a newer option for everyone 60 and up
Respiratory Syncytial Virus (RSV) vaccine is the newest addition to the list. It became available in 2023 and is now recommended for all adults 60 and older, regardless of health status. Unlike flu and COVID, you get RSV vaccine once — there is no annual booster — so it's a one-time shot and you're protected.
RSV is a virus that causes cold-like symptoms in young children but can be serious in older adults, leading to pneumonia and hospitalization. The vaccine reduces your risk of severe RSV disease. It's given as a single intramuscular injection, similar to a flu shot, and Medicare covers it with no copay.
Because RSV vaccine is new, not all pharmacies stock it yet, but your doctor's office almost certainly can order it or tell you where to get it. If you're over 60, ask about it at your next visit or call ahead to make sure it's available before you go in.
COVID-19 vaccine: annual boosters for most people
COVID-19 vaccine recommendations have settled into a pattern: most people over 65 need one updated booster per year, usually in the fall. The vaccine formulation changes each year to match circulating variants, similar to the flu vaccine. If you haven't had a COVID booster in the past year, you're due for one.
If you have a weakened immune system — from cancer treatment, an organ transplant, HIV, or certain medications — your doctor may recommend more frequent boosters. Ask at your next visit whether you fall into that category. COVID vaccines are available at doctor's offices, pharmacies, health departments, and many community clinics, and they're free under Medicare and most insurance plans.
How to keep track of what you've had
The easiest way to stay on top of your vaccines is to keep a written record or take a photo of your vaccine card and store it on your phone. When you get a vaccine, ask for a record on paper or ask the provider to note it in your medical record. If you use the same doctor's office for most of your care, they maintain a record for you, but if you see multiple providers, you need to keep your own copy.
Some states have vaccine registries that your doctor can access, but not all do, and not all providers use them. Your safest bet is to ask your doctor at your annual visit which vaccines you're due for and to write down the dates you receive them. Bring that list with you to every doctor's appointment so new providers can see what you've had.
If you've lost your records and can't remember what you've had, your doctor can order a blood test to check your immunity to certain diseases, though this isn't always necessary. In most cases, it's safe to get a vaccine again even if you're not sure whether you've had it before — the worst that happens is you get a little extra protection.
What to expect after vaccination
Most people have mild side effects or none at all. The most common are a sore arm, low-grade fever, fatigue, or mild body aches for a day or two. These are signs your immune system is responding, not signs something is wrong. Over-the-counter pain reliever can help if you're uncomfortable, and drinking extra water and resting usually does the trick.
Serious side effects are rare. If you develop a high fever, severe allergic reaction, or chest pain within hours of vaccination, call your doctor or go to an urgent care clinic. Keep the provider's name and the vaccine lot number so you can report it if needed. Your doctor can also review your medical history before vaccination to flag any reason to avoid a particular vaccine or to time it differently.
Frequently Asked Questions
Do I need all four vaccines if I'm over 65?
Most people over 65 benefit from all four, but your doctor may recommend differently based on your health history, allergies, or previous reactions. Talk to your doctor about which ones make sense for you. If you have a severe egg allergy, for example, some flu vaccines may not be right for you, but alternatives exist.
Can I get multiple vaccines at the same visit?
Yes. You can get flu, COVID, and RSV vaccines at the same visit — they can be given in different arms. Pneumonia vaccine can also be given at the same time, though if you need both PCV and PPSV, they're spaced apart. Ask your provider what they recommend for your situation.
What if I had pneumonia vaccine years ago — do I need another one?
Probably yes. If you had PPSV23 (the older pneumonia vaccine) more than a year ago, you now need PCV20. If it's been less than a year, wait until the year mark and then get PCV20. Your doctor can check your records and tell you exactly when you're due.
Is the vaccine safe if I'm on blood thinners or have other health conditions?
Vaccines are generally safe for people on blood thinners and with most chronic conditions. Tell your doctor about your medications and health history before vaccination so they can advise you on timing or technique — for example, using a smaller needle if you're on blood thinners. In almost all cases, the benefit of vaccination outweighs the risk.
Where can I get these vaccines if I don't have a regular doctor?
Pharmacies, health department clinics, and community health centers all offer vaccines. Call ahead to confirm they have the specific vaccine you need in stock. If you have Medicare, any provider that accepts Medicare can give you these vaccines at no cost. If you don't have insurance, ask about sliding-scale fees based on income.
