A lifetime.
Of protection.

Birth, 1–2 months, 6–18 months; catch-up through 18; adults 19–59, and 60+ with risk or seeking protection.

Usually a 3-dose childhood series. Adult series may use 2, 3, or 4 doses depending on product and circumstances. The infant final dose must meet minimum age and spacing requirements. Birth weight and maternal hepatitis B status can change immediate newborn care.

CDC hepatitis B vaccination · AAFP 2026 schedules & updates

Infancy only: 2 and 4 months, with a 6-month dose for some products.

Start no later than 14 weeks 6 days. No dose after 8 months 0 days. Product, actual date of birth, previous doses, severe combined immunodeficiency, and intussusception history matter. This oral live vaccine is not a general catch-up vaccine for older children.

CDC rotavirus guidance

2, 4, 6, 15–18 months; 4–6 years.

Protects against diphtheria, tetanus, and pertussis in children under 7. Children who start late need an interval-based catch-up plan. Older children use a Tdap/Td pathway rather than routine DTaP.

CDC DTaP / Tdap / Td guidance · CDC catch-up schedule

2, 4, sometimes 6 months; booster at 12–15 months.

Dose count depends on product and age at the start of catch-up. Most healthy children 5+ and adults do not need routine Hib; asplenia or stem-cell transplantation can change this.

CDC Hib guidance

2, 4, 6, 12–15 months; adults 50+; selected younger patients with risk.

Children generally use PCV15 or PCV20. Adults with no previous conjugate vaccine may use PCV20 or PCV21 alone, or PCV15 followed by PPSV23, usually 1 year later. Prior PCV13/PPSV23 history, immune conditions, and age change the plan. PCV21 is not the routine pediatric product.

CDC pneumococcal guidance · CDC adult schedule notes

2, 4, 6–18 months; 4–6 years. Catch-up for unvaccinated adults.

An unvaccinated adult usually receives 3 doses: first now, second in 1–2 months, third 6–12 months after dose 2. Fully vaccinated adults with increased exposure risk may need one lifetime IPV booster. Overseas oral-polio records need product/date review.

CDC polio guidance

Every season from age 6 months.

Children 6 months through 8 years with fewer than 2 documented previous doses before the season’s cutoff, or unknown history, generally need 2 doses at least 4 weeks apart. Adults 65+ should ask about an enhanced age-appropriate product. Use a pregnancy-appropriate product.

CDC 2026–27 influenza guidance · AAP 2026–27 influenza guidance · AAFP 2026–27 adult respiratory guidance

Review the current-season vaccine from 6 months; pediatric recommendations differ.

CDC recommends 2026–27 vaccination for adults 18+ and immunocompromised children; other children 6 months–17 years use shared decision-making. AAP recommends vaccination for all 6–23-month-olds and specified groups at 2–18 years, and permits vaccination when desired. AAFP recommends updated vaccination for adults 19+, with a second seasonal dose 6 months later at 65+. Product, prior doses, immune status, FDA labeling, and coverage must be checked.

CDC 2026–27 COVID-19 guidance · AAP 2026–27 pediatric COVID-19 guidance · AAFP 2026–27 adult respiratory guidance

12–15 months and 4–6 years; adult catch-up if not immune.

Adults usually need 1 dose without evidence of immunity; some need 2, including international travelers, health care personnel, and postsecondary students. Birth before 1957 can count as presumptive immunity in many situations. Travel may require an early infant dose that does not replace the routine series. Live vaccine: do not give during pregnancy; immune status matters.

CDC measles / MMR guidance

12–15 months and 4–6 years; catch-up if not immune.

Two doses are recommended without evidence of immunity. At 13+, doses are generally 4–8 weeks apart; younger children use different intervals. A clinician can confirm prior disease or other evidence of immunity. Live vaccine: do not give during pregnancy; immune status matters.

CDC varicella guidance

Start at 12–23 months; second dose at least 6 months later. Catch-up through 18.

Adults with risk factors or who request protection may be vaccinated. Common adult indications include travel, chronic liver disease, drug use, homelessness, and sexual exposure risk. Single-antigen products and combination hepatitis A/B products have different schedules.

CDC hepatitis A vaccination · CDC adult schedule notes

Tdap at 11–12 years; adult Td or Tdap boosters every 10 years after a complete primary series.

Adults who never received Tdap should receive a dose. An incomplete primary tetanus series needs a 3-dose catch-up plan, not just a 10-year booster. Tdap is recommended during each pregnancy at 27–36 weeks. Wound care may require an earlier booster and sometimes immune globulin; this planner does not manage wounds.

CDC DTaP / Tdap / Td guidance · CDC adult schedule notes · CDC pregnancy vaccine guidance

May start at 9; routine at 11–12; catch-up through 26; individual discussion at 27–45.

Usually 2 doses 6–12 months apart when started before 15, and 3 doses when started at 15+ or with certain immune conditions. Doses given too close together can change the number needed. Defer during pregnancy. No routine recommendation after 45.

CDC HPV guidance

11–12 years and booster at 16; earlier or additional doses for certain risks.

Risk-based indications include asplenia, complement problems or inhibitor therapy, HIV, certain travel, outbreaks, and some dormitory/military settings. A first dose given at 16+ can change the booster requirement. MenACWY does not replace MenB.

CDC meningococcal guidance

Individual discussion at 16–23 (preferred 16–18); from 10 for selected high-risk conditions.

Healthy adolescents choosing vaccination usually receive 2 doses 6 months apart. High-risk or rapid-protection pathways can use 3 doses and may need boosters. Products are not freely interchangeable. MenABCWY combinations may be used when both types are indicated.

CDC meningococcal guidance · AAFP 2026 schedules & updates

2 doses at 50+; from 19 with qualifying immune suppression.

Usually dose 2 at 2–6 months after dose 1; a shorter interval may be used for some immunocompromised patients. A delayed second dose does not require restarting. Prior shingles or the older Zostavax vaccine does not replace this series. Consider delaying until after pregnancy.

CDC shingles guidance

One dose at 75+; at 50–74 with increased risk. Maternal Abrysvo at 32–36 weeks, September–January.

Adult RSV vaccination is not annual. If previously vaccinated, another routine adult dose is not currently recommended. Maternal vaccination uses Abrysvo only; CDC does not currently recommend repeat maternal RSV vaccination in a later pregnancy. A child may instead receive an RSV antibody.

CDC adult RSV guidance · CDC maternal RSV guidance

First RSV season under 8 months; selected high-risk children 8–19 months in their second season.

Nirsevimab or clesrovimab are antibodies, not vaccines. Most infants do not need both maternal vaccination and infant antibody protection. Maternal vaccine timing, infant age, season, and prior antibody matter. AAP expanded some second-season risk criteria for 2026–27; second-season protection uses nirsevimab.

CDC infant RSV antibody guidance · AAP 2026–27 RSV guidance

For specified exposure or sexual-network risks and certain occupational exposures.

Usually 2 doses 28 days apart. It is not a universal vaccine. A known exposure needs prompt advice; do not wait for this routine planner. Routine extra boosters are not generally recommended for people vaccinated during the outbreak, except selected occupational situations.

CDC mpox / monkeypox vaccine guidance

Before exposure for selected animal work or travel; urgent care after a possible exposure.

Pre-exposure vaccination commonly uses doses on days 0 and 7, with later titer or booster requirements based on risk. A bite, bat exposure, or other possible exposure requires prompt medical/public-health assessment even if previously vaccinated.

CDC rabies pre-exposure guidance

Selected destinations / exposure; arrange a pre-travel visit.

Injectable and oral products have different minimum ages, timing, contraindications, and repeat-dose schedules. Itinerary and previous product determine what is needed.

CDC travel vaccines · CDC travel vaccine timing

Selected destinations and entry requirements.

A designated yellow-fever vaccination center reviews destination, age, immune status, pregnancy, and documentation requirements. Live vaccine; a dose is not automatically appropriate for every traveler.

CDC travel vaccines · CDC travel vaccine timing

Selected travel or residence in risk areas.

Need depends on location, season, duration, and outdoor exposure. A product-specific series is required; allow time before departure.

Selected travel to areas of active cholera transmission.

Not routine for most travelers. Review age, destination, outbreak information, and timing with a travel clinician.

CDC travel vaccines · CDC travel vaccine timing

Selected travel with tick exposure in endemic parts of Europe or Asia.

This vaccine does not prevent Lyme disease. A multi-dose series and possible later booster depend on ongoing risk.

CDC travel vaccines · CDC travel vaccine timing

Selected outbreak travel or extended residence in higher-risk areas.

CDC lists VIMKUNYA for eligible travelers 12+. Do not rely on older advice about IXCHIQ; its U.S. license was suspended and subsequently withdrawn. Use current CDC destination guidance.

CDC chikungunya vaccine guidance

Narrow indication for certain 9–16-year-old residents of endemic U.S. areas with confirmed previous infection.

Not a routine travel vaccine. Eligibility requires laboratory evidence and local program review. Product supply/availability must be verified before planning any dose.

CDC dengue vaccine guidance

Occupational, military, laboratory, outbreak, or public-health programs.

Anthrax, smallpox/orthopoxvirus, Ebola, and adenovirus vaccines have specialized indications. BCG is not routinely recommended in the United States. A specialty or public-health team determines product, access, and schedule; these are not automatically recommended by age.
