In this study researchers wanted to determine which sociodemographic factors were associated with delayed administration in measles, mumps and rubella (MMR) vaccine, both first and second doses, and to evaluate if there were differences in parental vaccine confidence of children who were delayed on MMR vaccine schedule compare to vaccinated on time.
A cross-sectional observational and analytical study conducted in the Region of Murcia, Spain, was performed on a sample of parents/guardians of 28,142 children born in 2019–2020 with a first MMR vaccine dose record and 30,996 born in 2016–2017 with a second one available in the vaccination registry database of the Region of Murcia (VACUSAN).
According to their findings you are more likely to delay or less likely to vaccinate if:
your child has motor and intellectual disabilities
you are a foreigner
you are single parent
you have a primary education degree
if it is your 2nd child
