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
