Background Compared to the general population, the Traveller community has substantial health inequalities. Vaccination coverage in Traveller children is estimated to be low and Travellers are at higher risk of vaccine-preventable diseases due to their social circumstances. Methods Audit of vaccination history of Traveller (n = 214) and non-Traveller (n = 776) children registered at a general practice in England. The Green Book childhood immunization schedule was used as a reference standard.
