| Test | Inactivated vaccine group (n = 15) |
Live attenuated vaccine group (n = 14) |
||
|---|---|---|---|---|
| No. (%) positive | GMT | No. (%) positive | GMT | |
| PRNT | 15 (100) | 1:292 | 14 (100) | 1:195 |
| HI | 13 (86.7) | 1:20 | 10 (71.4) | 1:17 |
| IFA (IgG) | 8 (53.3) | 1:99 | 5 (35.7) | 1:111 |
| IFA (IgM) | 0 | – | 0 | – |
| ELISA (IgG) | 0 | – | 0 | – |
| ELISA (IgM) | 0 | – | 0 | – |
ELISA = enzyme-linked immunosorbent assay; GMT = geometric mean titer; HI = hemagglutination inhibition test; IFA = indirect immunofluorescence assay; Ig = immunoglobulin; PRNT = plaque reduction neutralization test.
