简要总结
This study forms part of an integrated, multi-study effort to identify potential biomarkers of reactogenicity to vaccines. We have selected PET-CT as it is in routine clinical use and has been serendipitously shown to image lymph nodes and injection site inflammation after immunisation.The study's objectives are exploratory:
- To methodically characterise relative anatomical distribution and intensity of post-immunisation innate immune activation visualised by PET-CT after immunisation with adjuvanted and non-adjuvanted vaccines.
- To correlate PET/CT changes with diary card recorded symptoms of reactogenicity.
