Adult Vaccines: Which Ones You Need, When to Get Them, and What They Cover

Adult Vaccines

Book Appointment Today!

Three out of four U.S. adults are missing at least one vaccine that’s routinely recommended for them, not because they refused it, but because no one told them it existed.

Vaccines are not a childhood milestone you complete and move on from. The protection from several childhood vaccines fades over time. New vaccines have been developed and approved for adults that simply weren’t available a decade ago. And your risk profile changes with age; what you don’t need at 35, you may very much need at 55.

This guide covers the full adult vaccine schedule in plain language, organized by age group, with clear answers on what each vaccine covers, who needs it, and what insurance typically pays for. If you’re not sure where you stand, the most efficient path is a vaccine review with your primary care provider, who can pull your full immunization history and identify any gaps in a single visit.

Quick Answer - The Core Adult Vaccines at a Glance

Here’s the foundation of the adult immunization schedule, per the 2025–26 CDC and ACIP guidelines:

Flu (Influenza) — Every year, every adult, every season
COVID-19 — Updated seasonal formulation annually, per current CDC guidance
Tdap/Td — Once if you’ve never had Tdap; then a Td booster every 10 years; Tdap during every pregnancy
Shingrix (Shingles) — 2-dose series for all adults age 50 and older
Pneumococcal — Adults 65+; younger adults with chronic conditions
RSV vaccine — All adults 75+; adults 60–74 with risk factors; adults 50–59 with qualifying conditions (per April 2025 ACIP expansion)
Hepatitis B — Catch-up series for adults through age 59 who were never vaccinated
HPV (Gardasil 9) — Recommended through age 26; shared decision with provider ages 27–45
Note: Which vaccines you specifically need depends on your age, health history, and prior vaccination records. This guide provides the standard recommendations; your primary care provider will tailor them to your individual circumstances.

Why Vaccine Protection Doesn't End at Childhood

The assumption that childhood vaccines provide lifetime protection is one of the most persistent misconceptions in adult healthcare.

Several core vaccines wear off. The immunity provided by the DTaP series, which protects against diphtheria, tetanus, and pertussis, doesn’t last indefinitely. Tetanus protection fades and requires a booster every 10 years. Pertussis (whooping cough) immunity wanes even sooner, often within 5–10 years, which is why the Tdap version of the booster was specifically developed for adults and is now recommended as a routine replacement.

Some childhood vaccines simply didn’t exist for today’s adults. Routine hepatitis B vaccination wasn’t introduced in the U.S. until 1991. The HPV vaccine wasn’t available until 2006. The RSV vaccine for adults was approved in 2023. If you were vaccinated in the 1970s, 80s, or even 90s, you may have missed vaccines that are now standard through no fault of anyone.

Your immune system changes with age. A process called immunosenescence, the gradual weakening of immune function over time, means adults over 60 respond less robustly to pathogens and to standard vaccine formulations than they did at 30. This is precisely why certain vaccines for older adults use higher doses or adjuvants (immune-boosting additives) to generate adequate protection.

The result of all this: according to the National Foundation for Infectious Diseases, 3 out of 4 U.S. adults are missing at least one of the four most routinely recommended vaccines, influenza, pneumococcal, shingles, and Tdap. That’s not a failure of intent. It’s a failure of awareness that a single appointment with a primary care provider can fix.

Adult Vaccines by Age Group

Your vaccine needs shift meaningfully at each stage of life. Use the table below as a reference, then read the section that applies to your current age for the full explanation.

Age Group	Key Vaccines
All adults – annually	Influenza; COVID-19 (updated seasonal formula)
All adults – every 10 years	Tdap/Td booster; one Tdap if never received
All adults – catch-up if missed	Hepatitis B (3-dose series); HPV through age 26; MMR and Varicella if no evidence of immunity
Adults 50+	Shingrix (2 doses, 2–6 months apart); RSV if at increased risk
Adults 65+	Pneumococcal (Prevnar 20 or series); high-dose or adjuvanted flu; RSV vaccine
Chronic conditions	Earlier or additional pneumococcal, hepatitis B, flu, RSV
Pregnant adults	Tdap (every pregnancy, 27–36 weeks); flu every pregnancy; COVID update

In Your 30s and 40s

Adults in their 30s and 40s are often the most vaccine-neglected group, old enough for childhood vaccines to be a distant memory, young enough to feel invincible. This is when gaps quietly accumulate.

Tdap booster: If it’s been more than 10 years since your last tetanus shot, you’re overdue. More importantly, if you’ve never received the Tdap version specifically, which adds pertussis protection, you should get it once, regardless of when your last Td was. Adults are one of the primary sources of pertussis transmission to infants, who can’t be vaccinated until 2 months of age.
Annual flu shot: Adults in their 30s and 40s routinely skip this, believing the flu is only dangerous for the elderly. Influenza complications, pneumonia, hospitalization, and in some cases death, occur across all age groups, particularly in people with underlying conditions they may not yet know they have.
Hepatitis B catch-up: If you were born before 1991 and have no documentation of the hepatitis B vaccine series, the CDC recommends a 3-dose catch-up series through age 59. Hepatitis B vaccination was not routine before 1991, millions of adults in this age group were never vaccinated.
HPV (Gardasil 9): Recommended for all adults through age 26. For adults ages 27–45, it’s a shared clinical decision, your primary care provider can help determine whether HPV vaccination makes sense based on your relationship history and risk factors. HPV vaccination prevents cervical, anal, oropharyngeal, and other HPV-related cancers.
If you’re pregnant: Tdap during every pregnancy (ideally between weeks 27–36), flu shot during every pregnancy season, and the updated COVID-19 vaccine per current CDC guidance. These protect you and create antibody transfer to your newborn before they’re old enough to be vaccinated.

Contact WMG’s primary care services team if you’re unsure of your vaccination history, they can review records and help you identify where a catch-up series is needed.

Turning 50 What Changes at This Milestone

Age 50 is the most significant vaccination milestone in adulthood. Two major vaccine recommendations begin here, and both address conditions that become dramatically more common after this threshold.

Shingrix for all adults age 50 and older:

Shingrix is a 2-dose recombinant vaccine administered 2 to 6 months apart. According to the CDC’s shingles vaccination guidance, Shingrix is 97% effective in adults ages 50–69 and 91% effective in adults 70 and older.

What it protects against: shingles (herpes zoster), the reactivation of the same virus that causes chickenpox, and, critically, postherpetic neuralgia (PHN), the chronic nerve pain that follows shingles in approximately 10–18% of patients. PHN can persist for months to years and is notoriously difficult to treat.

Two questions WMG providers hear at every Shingrix conversation:

“I’ve already had shingles – do I still need the vaccine?” Yes. Shingrix is recommended even after a shingles episode. Having shingles once doesn’t reliably prevent recurrence, and Shingrix reduces that risk significantly.

“I already got the old shingles shot (Zostavax), do I need Shingrix too?” Yes. Zostavax was discontinued in the U.S. in 2020. Shingrix is substantially more effective and is recommended regardless of prior Zostavax vaccination.

Shingrix Facts:

97% effective in adults 50–69
91% effective in adults 70+
Protects against postherpetic neuralgia (PHN) by ~91%
2 doses required, given 2–6 months apart
Recommended even if you’ve had shingles or received Zostavax

RSV vaccine for at-risk adults starting at age 50:

As of April 2025, the ACIP expanded its RSV vaccine recommendation to include adults ages 50–59 who are at increased risk for severe RSV disease. Qualifying risk conditions include chronic heart disease, chronic lung disease (including COPD and asthma), diabetes, obesity, and immunocompromise.

RSV (respiratory syncytial virus) is not just a childhood illness. It hospitalizes approximately 160,000 U.S. adults per year and contributes to an estimated 10,000 deaths annually. It’s a single-dose vaccine, not an annual one.

Adults 65 and Older

Several vaccine recommendations become more pressing after age 65, and Medicare coverage details shift in ways worth understanding before you schedule.

Pneumococcal vaccine:

Pneumococcal bacteria are a leading cause of bacterial pneumonia, bloodstream infections, and meningitis in older adults. The current ACIP recommendation for adults 65+ is a single dose of Prevnar 20, or, for those who previously received an earlier pneumococcal vaccine, a combined series per your provider’s guidance.

Research published in CIDRAP found that adults who received both influenza and pneumococcal vaccines had significantly lower rates of death and hospitalization for pneumonia compared to those who received only one or neither. These two vaccines are most impactful when used together.

High-dose or adjuvanted flu vaccine:

Standard flu vaccine formulations generate a weaker immune response in adults over 65 due to immunosenescence. The CDC recommends one of three enhanced formulations for this age group: Fluzone High-Dose Quadrivalent, Fluad Quadrivalent (adjuvanted), or Flublok Quadrivalent (recombinant). Your WMG provider will ensure you receive the appropriate formulation at your annual visit.

RSV vaccine for all adults 75+:

Per the CDC’s RSV vaccine guidance, all adults age 75 and older should receive a single dose of RSV vaccine. Adults 60–74 with qualifying conditions (chronic heart or lung disease, diabetes, immunocompromise) also qualify. This is a one-time dose, not an annual vaccine.

New in 2025 – RSV Vaccine Expansion:
In April 2025, ACIP voted 14–0 to expand RSV vaccine eligibility to at-risk adults ages 50–59. If you’re in this range and have a chronic condition, ask your WMG provider whether you qualify at your next visit.

Medicare coverage for adults 65+:

This is where patients are most commonly confused. Medicare Part B covers flu vaccine, pneumococcal vaccine, COVID-19 seasonal vaccine, and hepatitis B (for medium/high-risk individuals), all at $0 with no deductible. Shingrix and the RSV vaccine are covered under Medicare Part D, not Part B. Whether there’s any out-of-pocket cost for these depends on your specific Part D plan. When you schedule a vaccine appointment at WMG, the team will verify your coverage before you arrive.

Adults with Chronic Conditions

Patients with chronic conditions often have more expansive vaccine needs than the standard adult schedule, and are among the most important people to have those conversations with their primary care provider.

Diabetes: Adults with diabetes should receive the pneumococcal vaccine (at younger ages than the standard 65+ recommendation), the hepatitis B 3-dose series (if not previously vaccinated, through age 59), annual flu vaccination, and the updated COVID-19 seasonal vaccine. Diabetes impairs immune response and increases the severity of most vaccine-preventable diseases.
COPD, asthma, and chronic lung disease: Pneumococcal vaccination is strongly recommended. Annual flu vaccination is critical. RSV vaccine is recommended for those 50–59 with qualifying conditions, and for all adults 60+ with chronic lung disease.
Chronic cardiovascular disease: Pneumococcal and annual flu vaccination are recommended. RSV vaccine eligibility should be discussed with your provider.
Immunocompromised adults (HIV, cancer treatment, long-term immunosuppressive therapy): Shingrix is recommended starting at age 18, not the standard 50 — due to dramatically elevated shingles risk. Live vaccines (MMR, varicella) are generally contraindicated. The full schedule requires provider-guided coordination.

The WMG chronic care and diabetes management teams review vaccine status as part of ongoing disease management, patients don’t need a separate appointment to address vaccination. For more on how primary care manages chronic disease risk factors, see how primary care catches health problems early.

Pregnant Adults

Vaccines during pregnancy are among the most clinically impactful interventions available in obstetric care because they protect two people at once.

Tdap every pregnancy: The Tdap booster should be administered during every pregnancy, ideally between weeks 27 and 36 of gestation. The maternal immune response transfers antibodies to the newborn through the placenta, providing pertussis protection during the critical first weeks of life before the infant’s own vaccine series can begin.
Flu every pregnancy: Influenza during pregnancy increases the risk of preterm delivery, low birth weight, hospitalization, and severe maternal illness. The flu shot is recommended during any trimester of pregnancy.
COVID-19 seasonal update: The CDC recommends the updated seasonal COVID-19 vaccine during pregnancy. Timing with your provider is appropriate.
Vaccines to defer: MMR and varicella (chickenpox) vaccines are live attenuated vaccines and are not given during pregnancy. If you need these, they should be administered before conception or after delivery.

WMG’s primary care services coordinate vaccine timing with OB/GYN care to ensure the right vaccines are given at the right gestational stage.

The Three Vaccines Most Adults Haven't Gotten (But Should)

If you’ve been generally keeping up with your flu shot and COVID boosters but haven’t thought carefully about the rest of your schedule, here are the three vaccines most commonly missing from adult records, and why they matter more than most people realize.

1. Shingrix (Shingles Vaccine)

Despite near-universal ACIP recommendation for adults 50 and older, shingles vaccine coverage among eligible adults remains low. The most common reason patients give: “I didn’t know I needed it.” Shingles isn’t just a rash; the virus affects nerve tissue, and the postherpetic neuralgia it leaves behind can be severe and debilitating. A 2-dose series with 97% efficacy is available.

2. RSV Vaccine

RSV vaccine was approved for adults in 2023. Millions of eligible adults have never heard of it. Yet RSV sends roughly 160,000 U.S. adults to the hospital each year, predominantly the elderly and those with chronic conditions. It’s a single dose. It’s covered under Medicare Part D. And it’s now available for at-risk adults starting at age 50.

3. Tdap Booster

The vast majority of adults have had a tetanus shot at some point, often after a cut or puncture wound. But the Tdap formulation (which adds pertussis/whooping cough protection) is a distinct vaccine that many adults have never received. Adults transmit pertussis to newborns who can’t yet be vaccinated, often without knowing they’re infected. One conversation with your primary care provider is all it takes to find out if you’re up to date.

Did You Know? 3 out of 4 U.S. adults are missing at least one of the four most routinely recommended adult vaccines: flu, pneumococcal, shingles (Shingrix), and Tdap. The gap is almost always a matter of awareness, not refusal.

What About Insurance and Cost?

Adult vaccines are among the most cost-effective preventive services in healthcare and in most cases, you shouldn’t be paying much or anything out of pocket.

ACA-compliant commercial insurance plans

Under the Affordable Care Act, non-grandfathered commercial health plans are required to cover all ACIP-recommended vaccines at $0 cost-sharing when administered in-network. This includes the flu shot, Tdap, COVID-19, hepatitis B, HPV, and other routine vaccines. No deductible. No copay.

Medicare Part B

Covers the following at $0 with no deductible:

Annual influenza vaccine
Pneumococcal vaccine
COVID-19 seasonal vaccine
Hepatitis B (for medium and high-risk individuals)

Medicare Part D

Covers: Shingrix (shingles vaccine) and RSV vaccine. These are drug plan benefits, not medical benefits, and the cost-sharing depends on your specific Part D plan. Some patients pay nothing; others pay a portion. Before scheduling Shingrix or an RSV vaccine, call your Part D plan or ask WMG staff to verify your specific coverage.

Medicare Coverage Quick Reference:

Vaccine	Medicare Part B ($0)	Medicare Part D (varies)
Flu (annual)	✅	—
Pneumococcal	✅	—
COVID-19 seasonal	✅	—
Hepatitis B	✅ (medium/high risk)	—
Shingrix	—	✅
RSV vaccine	—	✅

WMG verifies insurance coverage before vaccine administration at all locations, patients don’t need to navigate this alone.

Getting Your Vaccines at Windermere Medical Group

WMG’s board-certified providers administer all routinely recommended adult vaccines at all six North Georgia locations Cumming, Canton, Baldwin, Gainesville, Alpharetta, and Lawrenceville.

What a vaccine review at WMG looks like in practice:

Your provider pulls your immunization history and reviews your records
They assess your age, health conditions, and any chronic disease factors
They identify which vaccines you’re due for, overdue on, or have never received
They administer everything you’re ready for in the same visit; most adult vaccines can be co-administered with no problem
If your records are incomplete or unavailable, immunity titers (blood tests that check for existing antibody protection) can be done in-house to determine what you actually need

That’s one appointment. For most adults who haven’t reviewed their vaccines in years, that one visit is all it takes to get fully caught up.

The vaccine review can be added to your annual physical vs. wellness visit or scheduled as its own standalone appointment. It can also begin with a telehealth visit to review your records and eligibility before coming in.

WMG also verifies your insurance coverage before vaccine administration, so there are no billing surprises. For questions between appointments, the 24/7 Nurse Line is available at all times.

For a complete reference on which preventive care services, including screenings and vaccines, apply at your age, the preventive care checklist by age covers the full picture.

It's Not Too Late to Start

Many patients who haven’t been to a doctor in a while feel a combination of guilt and fear. Guilt about the time that’s passed. Fear about what might be found.

But here’s what the evidence consistently shows: early intervention works, and most of the conditions described in this article respond to treatment even when they’ve been quietly developing for some time. Prediabetes can be reversed. High blood pressure can be controlled. High cholesterol can be lowered. Chronic kidney disease can be slowed. These are not permanent sentences; they are conditions that respond to care.

The only condition that doesn’t respond well is one that isn’t found.

If it’s been a year, two years, or five years since your last checkup, the right time to schedule one isn’t “after the new year” or “when things slow down.” It’s now, while the window for early intervention is still open.

WMG’s preventive care program is designed for exactly this: patients at every stage, including the ones who are just getting started.

FAQs:

Q1. What vaccines do adults need every year?

Two vaccines are recommended annually for all adults: the influenza (flu) vaccine and the updated seasonal COVID-19 vaccine. The flu vaccine is reformulated every year to match circulating strains; last year’s shot does not protect against this season’s virus. The COVID-19 vaccine formulation is also updated annually by the CDC.

Q2. Which vaccines are recommended for adults over 50?

In addition to annual flu and COVID-19 vaccines and the Tdap/Td booster every 10 years, adults turning 50 should receive the Shingrix shingles vaccine (2-dose series, 2–6 months apart). Adults 50–59 with chronic conditions including heart disease, lung disease, diabetes, or immunocompromise may also now qualify for the RSV vaccine, per the April 2025 ACIP expansion.

Q3. Which vaccines are recommended for adults over 65?

Adults 65 and older should receive: pneumococcal vaccine (Prevnar 20 or a combination series); a high-dose or adjuvanted flu vaccine (not standard-dose); RSV vaccine (required for all adults 75+, recommended for adults 60–74 with risk factors); annual COVID-19 update; Shingrix if not already completed; and Tdap/Td every 10 years.

Q4. Is the shingles vaccine necessary even if you've never had shingles?

Yes. Shingrix is recommended for all adults age 50 and older regardless of whether they’ve had shingles. The varicella-zoster virus, which causes both chickenpox and shingles, lies dormant in nerve tissue after a chickenpox infection and can reactivate at any time, especially as immunity weakens with age. Shingrix prevents this reactivation and protects against postherpetic neuralgia, the chronic nerve pain that follows shingles in many patients.

Q5. What is the RSV vaccine for adults and who needs it?

The RSV vaccine is a single-dose vaccine that protects against respiratory syncytial virus, a respiratory illness that hospitalizes roughly 160,000 U.S. adults annually. The CDC recommends it for all adults 75 and older, adults 60–74 with qualifying risk conditions, and, as of April 2025, adults 50–59 who are at increased risk due to chronic heart disease, lung disease, diabetes, obesity, or immunocompromise. It is not an annual vaccine; one dose provides protection.

Q6. How often do adults need a tetanus booster shot?

A tetanus booster (Td) is recommended every 10 years for all adults. If you’ve never received the Tdap formulation which adds pertussis (whooping cough) protection, you should receive one Tdap dose to replace your next Td booster. Tdap is also recommended during every pregnancy, regardless of when the last booster was given.

Q7. Are adult vaccines covered by insurance?

Under the ACA, non-grandfathered commercial health plans must cover all ACIP-recommended vaccines at $0 cost-sharing in-network. Medicare Part B covers flu, pneumococcal, COVID-19, and hepatitis B vaccines at no cost. Shingrix and the RSV vaccine are covered under Medicare Part D, with cost-sharing that varies by plan. WMG verifies insurance coverage before administering vaccines.

Q8. Is the shingles vaccine (Shingrix) covered by Medicare?

Shingrix is covered under Medicare Part D, the drug benefit, not Medicare Part A or Part B. Whether there is any out-of-pocket cost depends on your specific Part D plan. Many Medicare beneficiaries pay little or nothing for Shingrix under Part D; others may have a copay. Call your plan or ask WMG to check your coverage before your appointment.

Q9. Can I get multiple vaccines in the same appointment?

In most cases, yes. The majority of adult vaccines, including flu, Tdap, Shingrix, hepatitis B, pneumococcal, and RSV, can be co-administered at the same visit without reducing their effectiveness. Your WMG provider will confirm which combinations are appropriate based on your health status and any contraindications. For most adults who are behind on multiple vaccines, a single appointment is enough to get fully current.

Q10. What vaccines do adults with diabetes need?

Adults with diabetes should follow the standard adult vaccine schedule and also receive: pneumococcal vaccine (recommended at younger ages than the standard 65+ threshold); hepatitis B (3-dose series if not previously vaccinated, through age 59); annual influenza vaccine; and the updated COVID-19 seasonal vaccine. Diabetes impairs immune response and increases the severity of influenza, pneumococcal disease, and hepatitis B infection. The WMG diabetes management program reviews vaccine status as part of routine chronic care.
