Table 3.
The risk of clinical FMD by number of doses of the FMD Asia-1 Shamir vaccine received in an animal's lifetime. All cattle were over four months old and number of vaccine doses is highly correlated with age. NB: in the TUR 11 vaccine investigations animals had only received a maximum of one dose as this was a new vaccine. Furthermore these cattle had never previously been vaccinated for FMD Asia-1.
| Number of vaccine doses in lifetime | Incidence risk | Relative risk |
|---|---|---|
| Cases/total | [95% CI] | |
| 0 | 14/21 (67%) | 0.75 [0.59–0.96] |
| 1 | 102/115 (89%) | Baseline |
| 2–5 | 58/84 (69%) | 0.78 [0.67–0.9] |
| ≥6 | 18/45 (40%) | 0.45 [0.35–0.58] |
