Honestly, the rules for COVID shots feel like they change as often as the weather. It’s exhausting. One minute we're talking about a "one and done" shot, and the next, there’s a new variant with a name like a Greek god or a Wi-Fi password. If you are over 65, you've probably felt that specific brand of frustration. You want to stay safe, but you also don't want to be a human pincushion for no reason.
So, let's get into the weeds of the 2025–2026 season. How often should seniors get covid boosters right now?
The short answer? Most seniors should be looking at two doses per year. But like everything in medicine, the "why" and the "when" are where things get a bit more nuanced.
The Magic Number: Two Doses a Year
For most adults aged 65 and older, the CDC and major health organizations like the American Hospital Association (AHA) are now coalescing around a twice-a-year schedule.
Basically, you get your updated 2025–2026 formula in the fall—usually alongside your flu shot—and then you follow up with a second dose about six months later.
Why the double-dip? Your immune system is a bit like a phone battery. It’s great right after a charge, but it drains. For seniors, that "drain" happens faster. Dr. William Schaffner, a well-known infectious disease expert at Vanderbilt, has often pointed out that "immunosenescence"—the natural weakening of the immune system as we age—means that the protection from a single shot just doesn't last as long as it does in a 20-year-old.
Recent data from the 2024–2025 season showed that the Moderna vaccine was about 53% effective against hospitalization. That’s good! But that number starts to dip after about four months. By the time six months roll around, that shield is looking a little thin. That second dose is essentially a mid-year top-off to keep you out of the hospital when the spring waves hit.
Wait, What If I Just Had COVID?
This is the "get out of jail free" card people always ask about.
If you just recovered from a bout of COVID, you have what doctors call "hybrid immunity." It’s a mix of the vaccine's protection and the natural antibodies your body made while fighting the real thing.
The current guidance is to wait three months after your symptoms started (or after your first positive test) before getting your next booster.
Could you get it sooner? Sure. Is it worth it? Probably not. Your antibody levels are likely peaking anyway, and waiting those 90 days gives your immune system time to "reset" so the booster actually does its job more effectively later on.
The "Shared Decision-Making" Loophole
You might hear your doctor mention "shared clinical decision-making."
This is basically medical-speak for: "It depends on your life."
If you are 66, run marathons, and have zero health issues, your doctor might say one dose a year is fine unless the local case counts skyrocket. On the flip side, if you have what the CDC calls "high-risk conditions"—things like BMI over 25, being a former smoker, or having heart disease—that second dose becomes much more of a "must-have" than a "nice-to-have."
What About the Immunocompromised?
This is a different bucket entirely.
If you are moderately or severely immunocompromised—maybe you're undergoing cancer treatment or take certain medications for autoimmune issues—the schedule is more aggressive. We are talking potentially every 2 to 6 months.
For this group, the goal isn't just to "boost" immunity; it's to try and build it in the first place, as the initial shots might not have "taken" as well. If this is you, the standard "twice a year" advice for seniors doesn't apply; you need a custom plan from your specialist.
Which Shot Should You Get?
The good news is that the "brand wars" are mostly over.
Whether you go with Pfizer (Comirnaty), Moderna (Spikevax), or the protein-based Novavax (Nuvaxovid), they all do the heavy lifting of preventing severe disease.
The 2025–2026 formula was specifically updated by the FDA to target the JN.1 lineage, specifically the LP.8.1 strain. These are the variants that have been doing the rounds lately.

Some people swear by Novavax because it’s a "traditional" vaccine technology and often has fewer "knock-you-on-your-butt" side effects like the fever and chills sometimes seen with the mRNA shots. Others stick with Pfizer or Moderna because that's what they've always had. Honestly? The best shot is the one available at the pharmacy five minutes from your house.
Surprising "Off-Target" Benefits
Here is something most people don't talk about.
Vaccines aren't just about the virus they name on the bottle. Research published in Age and Ageing has found a weirdly cool link between regular vaccination and reduced risks of dementia.
How? Well, when you get a severe infection like COVID, it causes massive inflammation in the body. That inflammation can mess with your brain. By preventing severe illness and the "brain fog" associated with Long COVID, these boosters might actually be helping preserve cognitive function as you age.
Think of it as a side benefit you didn't see coming.
Cost and Access: The Logistics
In 2026, most people shouldn't be paying a dime for these.
- Medicare Part B covers the COVID vaccine at 100% with no co-pay.
- Medicaid and most private insurance plans are still required to cover it.
- If you don't have insurance, some clinics still offer them for free, though the "Bridge Access" programs have become harder to find than they were in 2021.
Without insurance, the sticker price can be a gut-punch—anywhere from $224 to $250. It’s always worth checking with your local health department if you’re facing a bill like that.
Actionable Steps for Seniors Right Now
Don't overcomplicate this.
First, check the calendar. If it has been more than six months since your last shot, you are likely due. If you haven't had the updated 2025–2026 formula yet, that’s your priority.
Second, bundle your appointments. You can get your flu shot and COVID booster at the same time. Yes, your arm might be a little more sore, but it’s better than making two trips.
Third, monitor your local area. If cases are spiking in your city and you’re over 65, don't wait for the "perfect" six-month window. If you’re at four or five months, talk to your pharmacist about moving it up.
Lastly, keep a record. Digital apps are great, but a physical card or a photo of your record on your phone is still the easiest way to show a doctor what you’ve had and when. Staying protected isn't about being afraid; it’s about being smart so you can get back to living your life without worrying about every cough in the grocery store.
