Establishing and strengthening immunization in the second year of life (2YL) - resource page


As part a life-course approach to immunization, the importance of strengthening platforms for administering vaccines and other health interventions in the second year of life (2YL) is well-recognized. An increasing number of vaccine doses are recommended to be given after one year of age, and most infant vaccination can be caught up in the 2YL (if missed earlier). A strong platform in the 2YL is the first important step in extending immunization beyond infancy and encouraging the continuity of routine vaccination into preschool, school, adolescent and adult populations.
