Table 3.
Average population protection rates (proportion of population with titers ≥40). Post B/Vic vaccination protection rates are the proportion of individuals in the sample with titers ≥40. Post B/Yam vaccination protection rates are estimated based on the observed vaccine response (see Section 2). Results based on 2011 sera.
| A | Pre vaccination (%) | Post B/Vic vaccination (%) | Post B/Yam vaccination (%) | Post both vaccinations (%) |
|---|---|---|---|---|
| Vic | 49 | 88 | 49 | 88 |
| Yam | 26 | 49 | 100 | 100 |
| Average | 37.5 | 68.5 | 74.5 | 94 |
