DOI: 10.1007/s00415-022-11030-0
Abstract: The majority of multiple sclerosis [MS] patients treated with fingolimod fail to develop a protective level of IgG humoral and adaptive cellular immune responses following full BNT162b2 SARS-CoV-2 vaccination. To compare the efficacy of the… read more here.

DOI: 10.1038/s41541-018-0075-3
Abstract: Unlike drug dose optimisation, mathematical modelling has not been applied to vaccine dose finding. We applied a novel Immunostimulation/Immunodynamic mathematical modelling framework to translate multi-dose TB vaccine immune responses from mice, to predict most immunogenic… read more here.
