The dendritic cells which take up the inactivated virus vaccine will chop up the structural and spike proteins and display that on host MHC for T-cells and B-cells in germinal centers. The T-cells don't know if the protein fragments come from foreign particles or cell synthesis. The happens in both mRNA vaccines and inactivated virus vaccines and both require cross-presentation by the dendritic cells.
