Risk Difference, % (95% CI) b,c |
|---|---|---|---|---|
| Hospitalizations | ||||
| Real-world adherence to recommended schedule | 3,963 | 1,325,252 | 0.52 (0.50, 0.54) | 0.04 (0.03, 0.05) |
| Full adherence to recommended schedule | 3,008 | 1,081,828 | 0.48 (0.46, 0.50) | 0.00 |
| Emergency Department Visits | ||||
| Real-world adherence to recommended schedule | 23,821 | 1,309,279 | 3.32 (3.27, 3.36) | 0.17 (0.14, 0.19) |
| Full adherence to recommended schedule | 18,532 | 1,069,837 | 3.15 (3.10, 3.20) | 0.00 |
a
Recommended schedule defined as full three-dose RV5 series or full two-dose RV1 series.
b
Estimates adjusted for month of birth, year of birth, gender, maternal age, number of siblings, overnight hospitalization, health plan type, network of provider type, residence in a metropolitan statistical area, and geographic region.
c
95% confidence intervals were estimated using a non-parametric bootstrap (N=200).
CI indicates confidence interval; RV1, rotavirus monovalent vaccine; RV5, rotavirus pentavalent vaccine.
