| A | ITV | 75 | 97 | 74b | 89 |
| TV | 77 | 84 | 99 | 74 | |

a
Numbers in boldface are protection values ≥ 5% than those based on worm burden (WB).
b
Estimates of protection are based on means derived from time points before perfusion that were not significantly different from each other (epg, weeks 8, 9, and 10; CAA, weeks 6, 8, and 10; CCA, weeks 8 and 10). All datum points from which protection was calculated were significantly lower than their respective controls (P at least <0.05).
