Table 3. Summary of virus-specific CTL epitope hierarchies.
| Virus Name | Primary response (D8 or d10) | Memory response (D38) | Secondary response to H7N9 challenge (D70 after priming infection) | |
|---|---|---|---|---|
| Matched epitopes (between 1st and 2nd viruses) | Secondary response (D8 after 2nd infection) | |||
| AH/1(H7N9) | PB1 ≈ PA > NP | / | / | / |
| Ck/HK/TP38(H9N2) | PB1 ≈ PA ≈ NP | NP > PA ≈ PB1 | PB1, PA, NP | NP >> PA > PB1 |
