Tailoring immunisation programmes: Using behavioural insights to identify barriers and enablers to childhood immunisations in a Jewish community in London, UK.

Introduction: Due to regular vaccine preventable disease outbreaks and sub-optimal immunisation uptake in the London borough of Hackney, home to the largest Charedi Orthodox Jewish community in Europe, it was decided, in consultation with the community, to implement the WHO Tailoring Immunization Programmes approach (TIP).

Design: The WHO Tailoring Immunization Programmes (TIP) approach was used. TIP provides a framework based on behavioural insights methodology to identify populations susceptible to vaccine preventable diseases, diagnose supply and demand side barriers and enablers to vaccination and recommend evidence-informed responses to improve vaccination coverage.

Whole-genome sequencing revealed concurrent outbreaks of shigellosis in the English Orthodox Jewish Community caused by multiple importations of Shigella sonnei from Israel.

In December 2013, Public Health England (PHE) observed an increase in the number of cases of Shigella sonnei linked to the Orthodox Jewish Community (OJC). Ultimately, 52 cases of S. sonnei phage type (PT) P and PT7 were notified between November 2013 and July 2014.
