Vaccine effectiveness against RVGE hospitalization during the post-vaccine period by age group
| Age Group | Direct VE, % (95% CI) | Indirect VE, % (95% CI) |

*Represents significance at the alpha = 0.05 level
aIndirect and overall VE are equivalent for children, adolescents, and adults over 9 years of age because there are no vaccinated individuals in these age groups
