Among non\u2010elderly risk group conditions, Down syndrome showed the strongest positive association with receiving three doses (adjusted risk ratio [aRR] 1.62, 95% confidence interval [CI] 1.54\u20131.71), whereas chronic liver disease showed the strongest negative association (aRR 0.90, 95% CI 0.88\u20130.92). Higher vaccine uptake among the non\u2010elderly risk group was associated with increasing age, being born in Sweden, higher education, higher income and living in a household where other adults had been vaccinated.
