Sociodemographic predictors are associated with compliance to a vaccination-reminder in 9692 girls age 14, Denmark 2014–2015

Abstract

We aimed to identify sociodemographic predictors of compliance after receiving a personalised reminder on lacking vaccinations against MMR (Measles, Mumps, Rubella) and/or HPV (Human Papilloma Virus) among parents of Danish adolescent girls.A nationwide register-based study, including all 14-year-old girls (15 May 2014–14 May 2015) lacking either MMR, HPV-vaccination or both. Vaccination-compliance following a postal reminder was modelled using multivariable logistic regression and included the following socio-demographic predictors: maternal age, education, employment and ethnicity. Birth order, number of siblings, family-structure, location of residence, and household income.The parents of 9692 girls received a reminder. Out of 4940 exclusively lacking an HPV-vaccine, 15.3% were subsequently vaccinated. Among 2026 only lacking an MMR vaccination, 8.5% were vaccinated. Among 2726 girls lacking both, 5% received an HPV, 4.4% an MMR and 5.4% received both vaccinations. We identified sociodemographic differences between reminderletter-compliers and non-compliers, also according to vaccination types. Non-western descendants were more likely to receive HPV-vaccination, although the association was only significant for those who only lacked HPV (OR 2.02, 95% 1.57–2.59). For girls only lacking an MMR, regional differences were identified. Among girls lacking both vaccines, girls of mothers with intermediate (OR 0.63, 0.42–0.95) or basic education (OR 0.43, 0.24–0.75) were less likely to be vaccinated compared to girls of higher educated mothers.Reminders were in particular effective in increasing HPV uptake among immigrants of non-Western ethnicity. We found reminders to be less effective among less educated mothers whose daughters lacked both vaccines. To increase the coverage in this group, additional interventions are needed.

Defining the determinants of under-vaccination in migrant populations in Europe to improve routine and COVID-19 vaccine uptake: a systematic review

“…Personalised vaccination reminders had a larger positive effect on the uptake of childhood vaccines in non-Western mothers compared to Danish mothers. (54) Initiatives that built trust and shared responsibility through local partnerships and collaboration were also effective. (24,44,55) Health professionals suggested that, although costly, involving community members as vaccine advocates could help promote vaccination in communities that had experiences measles outbreaks.…”

Perceptions of cervical cancer prevention among a group of ethnic minority women in Denmark—A qualitative study

“…This was highlighted by a recent Danish study examining the effect of reminder letter in the national vaccination program [48], where the authors concluded that reminders were particularly effective in increasing HPVV among immigrants from non-Western countries (OR 2.02 [1, 57-2, 59]), which accentuates the benefits of such nudging interventions to help non-Western parents maintain compliance with vaccination recommendations. Furthermore, supporting the potential impact of implementing school-based HPVV interventions, a Swedish study investigating HPV uptake in different delivery systems (e.g.…”
