Adult vaccine schedule, what you actually need in 2026

Vaccines are not just for kids. The adult immunization schedule has changed in meaningful ways over the past five years. This paper walks through which vaccines apply at which age, which ones to prioritize, and the common reasons adults end up behind.

Annual vaccines

Two vaccines come up every year:

• Influenza (flu). One dose annually, ideally between September and November. Adults over 65 generally receive a higher-dose or adjuvanted formulation (CDC, 2026).
• COVID-19. The CDC currently recommends an annual updated dose for most adults, with additional doses for adults 65 and up and for those with weakened immune systems. The exact recommendation is updated each fall (ACIP, 2026).

If you got behind during the pandemic years, the answer is almost always to get caught up with the most recent formulation rather than chase the older doses.

Every 10 years

• Tdap booster. Tetanus, diphtheria, pertussis. One dose every 10 years. If you have not had a Tdap (not just Td) in the last decade, you are likely due. Pregnant patients receive Tdap during each pregnancy, ideally between 27 and 36 weeks, to protect the newborn from whooping cough.

In your 20s and 30s

The big additions for younger adults:

• HPV vaccine (Gardasil 9). Catch-up vaccination is recommended through age 26 and may be discussed with a clinician through age 45. The vaccine prevents the strains of HPV responsible for most cervical, anal, oropharyngeal, and certain other cancers.
• MMR. Most adults are covered from childhood. If your records cannot confirm two doses, a titer or a booster makes sense, especially if you work in healthcare, attend college in a high-exposure setting, or travel internationally.
• Varicella (chickenpox). Same idea. If you are unsure whether you had chickenpox or the vaccine as a child, a titer settles it.
• Meningococcal. College students living in dorms and military recruits are the most common adult candidates.

In your 40s

This decade is mostly maintenance, with two new items appearing toward the end:

• Continue annual flu and COVID, Tdap every 10 years.
• Hepatitis B. Universal vaccination for adults 19 to 59 is now recommended (CDC, 2022). If you completed the series as a child, you are set. If not, the three-dose (or two-dose Heplisav-B) series is straightforward.

At 50 and up

Two important additions:

• Shingles (Shingrix). Two doses, two to six months apart. Recommended for adults 50 and up, and for immunocompromised adults 19 and up. Shingrix is highly effective and the doses do not need to be repeated for at least 10 years.
• RSV (respiratory syncytial virus). Recommended for adults 75 and up, and for adults 60 to 74 at increased risk (chronic lung disease, heart disease, immunocompromised, residents of long-term care facilities).

At 65 and up

• Pneumococcal vaccines. Both PCV20 (or PCV21 if appropriate) and PPSV23 may be recommended depending on prior vaccination history. We walk through which schedule fits.
• High-dose or adjuvanted flu vaccine. Recommended over standard-dose flu vaccine in this age group.

Travel-related vaccines

If you are traveling internationally, plan ahead. Common travel vaccines we administer or refer for:

• Typhoid. For travel to South Asia, parts of Africa, and Central and South America.
• Yellow fever. Required for entry into certain African and South American countries.
• Japanese encephalitis. For longer rural travel to Asia.
• Hepatitis A. Often added for travel to many lower-resource regions.
• Rabies pre-exposure. Considered for travelers with high animal contact in endemic areas.

Some travel vaccines need to be started weeks before departure to be fully effective. Plan at least a month ahead when possible.

Pregnancy-specific

If you are pregnant or planning a pregnancy:

• Tdap during each pregnancy (27 to 36 weeks).
• Influenza any trimester.
• RSV vaccine between 32 and 36 weeks of pregnancy if it is during the September to January window, to pass antibodies to the newborn.
• COVID-19 per current CDC guidance.
• Make sure MMR and varicella status is confirmed before pregnancy, because these live vaccines cannot be given during pregnancy.

If you are immunocompromised

Patients on immunosuppressive medications, biologics, chemotherapy, or with HIV may need a different schedule. Inactivated vaccines are usually safe and important. Live vaccines (MMR, varicella, yellow fever, intranasal flu) are often avoided. We coordinate with your specialist.

Why we recommend what we recommend

We follow the Advisory Committee on Immunization Practices (ACIP) recommendations, which are the basis for the CDC schedule. We do not push vaccines you do not need, and we do not skip the ones you do. If something on the schedule does not feel right, we walk through the reasoning, the alternatives, and the data.

The next step

If it has been a few years since anyone reviewed your vaccine record, schedule a quick visit or bring it to your next annual physical. We pull up your record, identify what is due, and either administer it at the visit or schedule a return.
