Grace, I should do some Medline searching on this. I think there is
literature out there on route of immunisation and this is one of those
subjects where every Ph.D. student re-invents the wheel. BTW, an
excellent way to use Medline is the NCBI Pubmed search engine at

Personally, I think material injected into the PEC drains into the blood
quickly and then gets pretty much everywhere. However, I guess the
Freunds might keep it in the PEC as a big oily blob.
