The adult vaccine schedule you can actually use this year

If you’re not sure which vaccines you still need as an adult, you’re not alone. Some shots are routine at certain ages, others depend on your health or work, and a few are needed only before travel or during pregnancy. Below, you’ll find an at‑a‑glance way to confirm which vaccines apply to you right now and how to time them across the year. Every fact here comes from U.S. public‑health sources and reflects the current CDC adult schedule and updates published through the 2025–26 season.

First, a quick self‑check: what applies to you?

• Your age this year (19–26, 27–49, 50–64, 65+, 75+)
• Pregnancy status and timing (any trimester now or upcoming)
• Medical conditions or medicines that weaken immunity
• Work, school, housing, or travel exposures (healthcare, lab work, dorm living, military, international trips)

The CDC’s adult schedule groups vaccines by age and by risk; the current grid and explanatory notes are posted on the CDC site for clinicians and the public (adult schedule; schedule notes). The schedule for 2025 includes updates on COVID‑19, influenza, pneumococcal, and RSV vaccines summarized in the CDC’s MMWR notice for adults aged 19 and older (2025 ACIP adult schedule).

Which vaccines are routine by age?

• Influenza (flu): everyone 6 months and older should get a seasonal flu vaccine each year; for 2025–26, ACIP again recommends annual vaccination for all persons without contraindications (ACIP 2025–26 flu recommendations; see CDC’s consumer summary on who needs a flu vaccine and timing in September–October for most adults here).
• Tdap/Td: if you never had Tdap as a teen/adult, get 1 Tdap now, then Td or Tdap every 10 years; during each pregnancy, get Tdap at 27–36 weeks, preferably earlier in that window (CDC pertussis in pregnancy).
• COVID‑19: CDC’s schedule lists at least 1 dose of the current‑season vaccine for adults, with at least 2 doses for ages 65+; details and timing vary by prior doses and risk—check the CDC COVID‑19 guidance page for the 2025–26 season (consumer schedule grid; 2025–26 clinical guidance).
• Zoster (shingles): 2 doses of recombinant zoster vaccine (RZV, Shingrix) for all adults 50+, 2–6 months apart; immunocompromised adults 19+ should also receive 2 doses (a 1–2 month interval can be used if needed) (CDC shingles vaccine; clinical considerations).
• Pneumococcal (pneumonia): for adults who haven’t had a conjugate pneumococcal vaccine, CDC recommends either a single dose of PCV20 or the newer PCV21, or PCV15 followed by PPSV23; adults 50+ and many younger adults with certain conditions qualify—timing and product choice are in CDC’s pneumococcal pages and 2024 MMWR on PCV21 (CDC pneumococcal for adults; PCV21 guidance; provider job aids here).
• RSV (respiratory syncytial virus): one dose is recommended for all adults 75+; adults 50–74 at increased risk for severe RSV illness should also receive one dose; others 60–74 may decide with their clinician (CDC RSV vaccines for adults; update summarized in the 2024 MMWR here).

Which vaccines depend on your history or situation?

• MMR (measles, mumps, rubella): adults without evidence of immunity should have at least 1 MMR dose; some (students, international travelers, healthcare personnel) need 2 doses, 28 days apart (CDC MMR for adults).
• Varicella (chickenpox): adults without evidence of immunity need 2 doses 4–8 weeks apart; evidence includes documented vaccination, lab proof, or provider‑verified prior disease (CDC varicella guidance; definition of “evidence of immunity” in CDC schedule notes here).
• Hepatitis B: universal vaccination is recommended for adults 19–59; adults 60+ with risk factors should be vaccinated, and those 60+ without known risks may also receive it (ACIP universal HepB for adults).
• Hepatitis A: adults at risk for infection or severe disease should get a 2‑dose HepA series or a 3‑dose HepA‑HepB combination series as outlined in the CDC notes.
• HPV: catch‑up vaccination through age 26 if not adequately vaccinated; ages 27–45 may choose vaccination through shared clinical decision‑making (2 or 3 doses depending on when the series starts) (CDC HPV recommendations; ACIP rationale in MMWR here).
• Meningococcal: adults at increased risk (e.g., certain medical conditions, outbreak exposure, travel to endemic areas, first‑year college students in residence halls, military recruits) should receive MenACWY and/or MenB per CDC guidance; healthy 16–23‑year‑olds may get MenB based on shared decision‑making, with an approved pentavalent option when both types are indicated at the same visit (CDC meningococcal for adults; shared decision‑making explained by CDC; ACIP 2025 pentavalent recommendation here).

How to turn this into a personal plan

1. List what you’re due for now. Use the CDC grid to mark each vaccine you need this year by your age and risk, then read the vaccine‑specific notes for intervals and exceptions.

2. Time your seasonal shots. For most adults, September–October is a good window for flu; COVID‑19 timing depends on your last dose and risk; RSV for eligible adults is typically given before RSV season (flu timing; COVID‑19 guidance; RSV adults).

3. Stack doses efficiently. Many vaccines can be given at the same visit at different sites; your clinician or pharmacist will sequence any that need spacing (e.g., live vaccines, specific product intervals) per CDC notes.

4. If you’re pregnant. Plan for Tdap at 27–36 weeks, and an inactivated flu shot during flu season; other vaccines are situation‑specific—review CDC’s pregnancy vaccine guidance with your OB team (CDC pregnancy guidelines).

5. Keep proof. Ask for an updated record after each visit and store it in your patient portal or phone wallet. That helps avoid unnecessary repeat doses and speeds care during travel or outbreaks.

How to know it worked (and what to watch for)

• Protection starts on different timelines. Flu and COVID‑19 protection builds over about 2 weeks; shingles protection builds over the 2‑dose series; pneumococcal protection begins after the dose(s) you receive. Your clinician will advise on exposure precautions during that period; general vaccine effectiveness and timing are summarized in CDC vaccine pages for each disease (e.g., flu facts and shingles).
• Side effects are usually mild (sore arm, fatigue, low fever). Read the fact sheet you’re given and call your clinician for symptoms that worry you. Safety monitoring and contraindications are listed in the CDC adult schedule appendix and vaccine‑specific pages (contraindications/precautions).
• High‑risk settings or travel. If you’re headed to a dorm, military basic, lab work with meningococcal exposure, or international travel, check whether MMR, MenACWY, MenB, HepA/B, or other vaccines are indicated (see meningococcal for adults and CDC notes linked above).

Quick reference: common adult vaccines and typical triggers

• Annual: influenza for everyone; COVID‑19 per current‑season guidance (at least 2 doses if 65+) (ACIP flu summary; consumer schedule).
• Age‑based: shingles at 50+ (2 doses); pneumococcal at 50+ or earlier with conditions; RSV one dose at 75+ (and at 50–74 if increased risk) (zoster; pneumococcal; RSV adults).
• Pregnancy: Tdap each pregnancy at 27–36 weeks; inactivated flu vaccine during flu season.
• History‑based: MMR and varicella if no evidence of immunity; HPV catch‑up through 26, shared decision‑making at 27–45; HepB for all 19–59 (and 60+ with risks; 60+ may receive) (MMR; varicella; HPV; HepB).

If you want help turning this into a one‑page checklist for your next visit, bring the CDC grid and circle what applies to you this month. That way you and your clinician can schedule any multi‑dose series and seasonal shots on one calendar year.
