Adult Vaccine Schedule: What You Need at Every Age

Vaccines are not just for children. Adult vaccination gaps cause tens of thousands of preventable hospitalizations every year — mostly in people who assumed they were “done.”

Here is the complete adult schedule by age, what each vaccine protects against, and who needs a catch-up.

The Vaccines Most Adults Miss

1. Tdap / Td (tetanus, diphtheria, pertussis).
– Every 10 years after the initial series
– One dose of Tdap in adulthood, then Td or Tdap boosters
– Pregnant women: one Tdap dose each pregnancy (protects the baby from whooping cough)
– Tetanus boosters are essential — tetanus does not clear on its own and is lethal

2. Flu (influenza) vaccine.
– Yearly, every year — the strain changes each season
– Recommended for everyone 6 months and older
– Most important for: older adults, pregnant women, people with chronic conditions, healthcare workers
– October is the ideal time, but late is better than never

3. COVID-19 vaccine.
– Primary series + updated booster (typically annually, aligned to the current variant)
– Recommended for everyone 6 months and older
– Especially important for people 65+, immunocompromised, pregnant, or with chronic conditions

4. Shingles (Shingrix).
– Two doses, 2-6 months apart
– For everyone 50 and older — even if you had chickenpox (which is everyone born before 1990)
– Also for people 19+ who are immunocompromised
– Shingles is not “just a rash” — it causes severe nerve pain that can last months or years (postherpetic neuralgia)

5. Pneumococcal (pneumonia) vaccine.
– All adults 65+ (the PCV series, often one or two doses depending on history)
– Adults 19-64 with chronic conditions: smoking, asthma, diabetes, heart/lung disease, immunocompromise — asthma qualifies
– Prevnar and Pneumovax are the common brands; the schedule depends on which you have had

6. HPV (human papillomavirus).
– Catch-up to age 26 for everyone (originally scheduled as teens)
– Ages 27-45: approved and available — discuss with your doctor, especially if you have not been sexually active with multiple partners
– Prevents cervical, anal, oral, and penile cancers — one of the most effective anti-cancer vaccines in existence

7. Hepatitis B.
– All adults who were not vaccinated as infants (recommended for everyone by the CDC)
– 2-3 dose series
– Blood-borne; chronic infection causes liver damage and liver cancer

8. MMR (measles, mumps, rubella).
– Adults born before 1957 are considered immune (measles was ubiquitous)
– Anyone else without proof of vaccination: 1-2 catch-up doses
– Mumps outbreaks still occur in adults — especially crowded settings (colleges, workplaces)

9. Varicella (chickenpox).
– Anyone without documented chickenpox history or vaccination: 2 doses
– Chickenpox in adults is far more severe than in children — serious pneumonia risk

10. RSV (respiratory syncytial virus).
– Newer vaccine: for adults 60+ (one dose, discuss with your doctor)
– Also recommended for pregnant women (to protect the newborn) and high-risk adults
– RSV causes serious lower-respiratory illness in older adults

The Schedule by Age

The “Immune Memory” Rule

Vaccines protect differently over time:

• Annual: flu, COVID (variants change)
• Every 10 years: tetanus/diphtheria
• One series, lifelong: HPV, hepatitis B, MMR, varicella (for most people)
• Age-gated: shingles (50+), pneumococcal (65+ or high-risk), RSV (60+)

If you have no record of childhood vaccines, the standard approach is to re-vaccinate rather than test — catching up is safe and recommended.

Where to Get Vaccines

• Your GP/primary care — most convenient for scheduling
• Pharmacies — flu, COVID, shingles, Tdap, and pneumococcal are routinely available same-day at CVS, Walgreens, and similar
• Travel clinics — for destination-specific vaccines (yellow fever, typhoid, hepatitis A)
• Local health departments — low-cost options for the uninsured

Tip: when you get one vaccine, ask the pharmacist or doctor to check your full record and flag what is due. Most systems will do this automatically.

How to Know Your Vaccine Status

• US: your state’s immunization registry, your doctor’s records, or the CDC’s Vaccine Finder
• UK: your NHS records (via GP surgery)
• Canada/Australia: provincial/state immunization registries
• Lost your card? Most records are now digital — a simple request retrieves them

The Bottom Line

If you do only one thing this year, book a “catch-up” appointment with your doctor or pharmacist and review: Tdap, flu, COVID, and (if 50+) shingles. Those four cover the highest-risk preventable diseases for adults. Good hand hygiene covers the rest.

When to See a Doctor

• Any severe allergic reaction after a vaccine – difficulty breathing, swelling of the face or throat, or widespread hives – call emergency services
• You have had Guillain-Barre syndrome, or a severe reaction to a previous dose
• You are pregnant, or planning pregnancy – live vaccines such as MMR and varicella are usually avoided
• You are immunocompromised, on chemotherapy, or have had a transplant – the schedule and vaccine types change
• You have a moderate or severe illness with fever – usually wait until you have recovered
