The preferred formation of a CDR3 motif that constrains TCR selection by requiring conservation of the V-D recombination site would seem to limit the possibilities for convergent recombination, suggesting that selection pressure may be imposed by conformational requirements of the TCR-peptide-MHC interface

Furthermore, the weak strength of vaccines administered In-may also be from the unavoidable restriction of the pet model used; intranasal vaccination in little pets may cause ingestion and inhalation of vaccine antigens, which affects vaccine dosage [49] consequently
