WHO recommendations for routine immunization - summary tables (January 2025)
Children aged 2–11 months require 2 doses administered. For monovalent MenC conjugate vaccine, one single intramuscular dose is recommended for children aged ≥ 12 months, teenagers and adults. Children aged 2–11 months require 2 doses administered. Children aged 2–11 months require 2 doses administered at an interval of at least 2 months. For monovalent MenC conjugate vaccine, one single intramuscular dose is recommended for children aged ≥ 12 months, teenagers and adults. It is not yet known whether booster doses will be needed for long-term protection in healthy individuals who received primary vaccination when aged ≥ 12 months.
