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 a Welsh Government early years programme, delivered by local authorities that provides support for families with children aged four and under, particularly in disadvantaged areas with the aim of improving outcomes.

The programme provides a package of support including funded, part-time, high-quality childcare for two-year-olds, enhanced health visiting, parenting support and support for speech, language and communication.

Flying Start was launched in 2006, and all four elements were expanded to more families from September 2022.
