Twisty if you look on page 9 it states
“ Once the Nuvec® vaccine particle reaches the target, such as an antigen-presenting cells, the particle is internalised into the cell via a process known as endocytosis. This encapsulates the Nuvec® complex into a membrane-bound vesicle known as an endosome. The endosome has a more acidic pH level than observed in blood vessels. This pH change causes the PEI to change charge and the silica spikes to disintegrate. This releases PEI, which ruptures the endosome and releases the DNA/RNA payload into the cell cytoplasm. Depending on whether the payload is DNA or RNA-based determines the next step. If the payload is DNA-based, the nucleic acid is delivered to the nucleus, the part of the cell which carries most of the genetic information. Once in the nucleus, the pDNA is transcribed into mRNA, which is released into the cytoplasm and translated into the protein antigen.”
To me it seems the delivery system that has been proven would deliver RNA or DNA into cell cytoplasm but I admit I’m no scientist.
