Use the current schedule. Every time.
Immunization recommendations can change as evidence, disease patterns, vaccine products, and clinical guidance evolve.
ACIC links to current vaccine schedule resources and professional guidance so providers, families, and community partners are not relying on outdated PDFs, old screenshots, or saved printouts.
Do not use old printed schedules, saved PDFs, or screenshots for clinical decisions. Always verify current guidance before use.
