"Neither primed CD4+ nor CD8+ T cells appeared critical for immunoglobulin class switching, the development of immunological memory, or protection from a second infection." this seems reasonable, it never made sense to me that one can not get reinfected. for depletion, it would seem then a counter to the second dose argument, yet again I revert back to my statement above that to me I'm positioned in that I can wait for the fog to clear a bit. A lot of this seems very early days in the Iraq war when the media and admin were in the same boat for the purpose of the invasion etc.
