Table 7. Logistic models to high* neutralizing antibody titer for yellow fever 30–45 days after vaccination in adults (between 18 and 50 years) (n = 240).
| Variables | Crude OR (95% CI) |
Adjusted OR** (95% CI) |
|---|---|---|
| μFRNT dengue pre-vaccination | ||
| Positive | 0.35 (0.15–0.76) | 0.34 (0.14–0.74) |
| Negative | 1 | 1 |
| PRNT90 Zika pre-vaccination | ||
| Positive | 1.51 (0.49–6.64) | 2.06 (0.64–9.22) |
| Negative | 1 | 1 |
| Age (year) | 1.02 (0.98–1.07) | 1.02 (0.98–1.06) |
Pre-vaccine yellow fever seropositive individuals and individuals who had seronegative and indeterminate titers 30–45 days post-vaccination were excluded; Data from the subsample of participants tested for μFRNT dengue and PRNT90 Zika.
Reference category: μFRNT YF ≤1.106 (low).
Model adjusted by μFRNT dengue pre-vaccination, PRNT90 Zika pre-vaccination, Age (years) and sex: AIC = 230.
