This is an iatroX educational summary of named United States sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Use the named authority, current FDA labeling, applicable state law, payer rules and local protocol where relevant.

Scope of this summary

People from birth through age 18 years receiving routine or catch-up vaccination in the United States. The current online CDC/ACIP schedule, its notes and interim recommendations must be consulted at each encounter.

The Bottom Line

  • Use all parts of the current schedule together: the age table, catch-up table, medical-indication table and vaccine-specific notes. A colored cell alone does not capture minimum ages, intervals, contraindications or special situations.
  • Review the complete documented record at every clinical opportunity and administer all vaccines due when no contraindication exists; a delayed series usually continues and is not restarted.
  • Apply catch-up minimum ages and intervals exactly, distinguishing minimum from routine intervals and checking product interchangeability, dose count and age at prior vaccination.
  • Use the medical-indication notes for pregnancy, immunocompromise, asplenia, complement inhibitor use, chronic heart, lung, liver or kidney disease, diabetes and other conditions that alter product or timing.
  • Plan adolescent vaccines, travel and outbreak needs in advance and use reminder, recall and standing-order systems while preserving informed consent and state-specific requirements.

Practical clinical workflow

1
Reconcile the state registry, electronic record, parent-held record and reliable external documents; do not count an undocumented verbal history except where the current ACIP note permits it.
2
Determine age today, prior valid doses, medical indications, pregnancy possibility, immune status, anatomic or functional asplenia, medicines, allergies, travel, housing or occupational exposure and outbreak context.
3
Open the live CDC schedule and vaccine-specific notes, calculate each due or catch-up dose and check minimum interval, formulation, route, site and coadministration rules.
4
Screen only for true contraindications and precautions, give the current Vaccine Information Statement, answer questions and document product, lot, site, date and the next due date.
5
Observe and manage immediate reactions, report qualifying adverse events, update the registry and provide a clear catch-up plan rather than leaving an incomplete series without follow-up.

Safety boundaries and escalation

  • Do not administer a live vaccine when the current ACIP schedule lists pregnancy, severe immunocompromise or another contraindication; the exact restriction is product and patient specific.
  • A severe allergic reaction to a previous dose or component requires vaccine-specific specialist assessment, but minor illness, antibiotics and many commonly cited concerns are not automatic contraindications.
  • Prevent administration errors by verifying product, formulation, age indication, route and spacing before injection; pediatric and adult formulations are not interchangeable unless the notes say so.
  • Treat anaphylaxis immediately and report clinically significant adverse events through the appropriate federal system; syncope prevention and post-vaccination observation are particularly important in adolescents.

Localization

ACIP recommendations and CDC schedules are national clinical guidance, while school mandates, consent, registry and exemption law are state or territorial. The live CDC portal and its July 2, 2025 addenda were directly rechecked on 2026-08-20; use the live schedule and notes at every encounter because interim recommendations can change.
