Overview

Summary of dataset and variables

This dataset provides data on the uptake of childhood immunisations for cohorts of children becoming age 4 during the financial year for which the statistics are presented. The children are those resident in Flying Start and non-Flying Start areas at the time the data is extracted and are presented by local authority.

Vaccines are offered to all children, as part of the routine childhood immunisation schedule, to protect them against Diphtheria, Tetanus, Pertussis, Polio, Haemophilus influenzae (Hib), Measles, Mumps, Rubella, Meningitis C and Pneumococcal infection (PCV). Vaccinations are given according to a routine childhood immunisation schedule starting 8 weeks after birth, and the aim is for all children to be fully immunised by their fourth birthday.

Flying Start is the Welsh Government early years programme delivered by local authorities in Wales. It is aimed at improving outcomes for families with children under 4 years of age in some of the most disadvantaged areas of Wales.

Expansion of all four elements of Flying Start began in September 2022, it included: funded part-time, high-quality childcare for 2 year olds; parenting support; enhanced health visitor support; and support for speech, language and communication.
