There is no spike protein in the vaccine. There is mRNA. That mRNA needs ribosomes to make the spike protein. So think about where there are ribosomes, and where the protein is made, and you’ll find the correct answer.
I don’t know where you heard the second point, but it is equally incorrect. The mRNA encodes just the spike, with two mutations to lock it into a pre-fusion conformation. Nothing there that qualifies as a “larger stable base”. The sequence is found here: https://web.archive.org/web/20210105162941/https://mednet-co...
