Hanna Josefsson

I am a PhD student at the Unit of Clinical Epidemiology at Karolinska Institutet and have a background in biomedicine (BSc) and public health (MPH). My PhD project focuses on vaccination during pregnancy – primarily vaccines against influenza, pertussis, and RSV – with an emphasis on uptake, effectiveness, and hesitancy. The project takes a mixed-methods approach, combining national Swedish register data with qualitative interviews.
