Summary:•Children living in deprived vs affluent areas are >10 % less likely to be vaccinated.•Mothers vaccinated in pregnancy vs unvaccinated 40% more likely to vaccinate child.•Pregnancy is an opportunity to promote both maternal & childhood vaccines to parents. We examined the association between socio-demographic determinants and uptake of childhood Measles, Mumps & Rubella (MMR) vaccines and the association between pregnant women’s pertussis vaccine uptake and their children’s MMR vaccine uptake. We used nationally-representative linked mother-baby electronic records from the United Kingdom’s Clinical-Practice-Research-Datalink. We created a birth cohort of children born between 01.01.2000 and 12.12.2020. We estimated the proportion vaccinated with first MMR vaccine by age 2 years and first and second MMR vaccines by age 5 years. We used survival-analysis and Cox proportional hazard models to examine the association between deprivation, ethnicity and maternal age and pertussis vaccination in pregnancy and children’s MMR uptake. Overall, 89.4 % (710,797/795,497) of children had first MMR by age 2 years and 92.6 % (736,495/795,497) by age 5 years. Among children still in the cohort when second MMR was due, 85.9 % (478,480/557,050) had two MMRs by age 5 years. Children from the most-deprived areas, children of Black ethnicity and children of mothers aged
