Research description

My research is within infectious disease epidemiology and has a main focus on prerequisites for optimal vaccination strategies. As vaccination is one of our most important tools in the combat of infectious disease it is important to maintain public trust. One way of doing this is to evaluate vaccine effectiveness and safety on a population-based level. We have in the past decades reduced the infectious disease burden with vaccination and we are now facing a situation where younger generations who never confronted the actual disease tend to shift their focus toward adverse events instead leading to anti-vaccine movements and misunderstandings about real and perceived risks. Further, with antibiotic resistance we need to develop new vaccines that need to be evaluated on a population-based level.

In addition to this I am also involved in several projects optimizing cervical cancer prevention through both vaccination and screening. In our group we use sophisticated population-based register matching and modelling methods in combination with lab and questionnaire data to evaluate:

1) Short and long term vaccine safety and effectiveness to ensure the reliability of the vaccines;

2) Infectious disease burden to investigate both effectiveness and cost-effectiveness of vaccine programmes;

3) Cervical screening setting and recommendations in a changing reality, as the HPV vaccine and new screening techniques will change the program we have today.
