==== Body
pmcTo the Editor:

We thank Daungsupawong and Wiwanitkit for their comments1 on our work published in a recent issue of the Journal of Allergy and Clinical Immunology: Global and titled “COVID-19 vaccine uptake among young adults: Influence of asthma and sociodemographic factors.”2 In that study, we concluded that COVID-19 vaccine uptake among young adults is lower in individuals from households with lower socioeconomic status and among those with asthma, including uncontrolled asthma.

However, we would like to highlight the comment regarding vaccine data presented in our study, as the data were not self-reported. Information on vaccine uptake was obtained by linkage to the National Vaccination Register using personal identity numbers, with the Public Health Agency of Sweden responsible for the vaccination register. This register is mandatory, which means that all vaccinations against COVID-19 in Sweden are recorded.
