PRIMARY outcome

Timeframe: Child's immunization status at 8 months of age

Population: Mean percent days under-immunized of child participants by study arm

Mean percent days under-immunized among children of parents who received (vs. did not receive) the intervention

Child's Mean Percent Days Under-immunized
19.1 percentage of days under-immunized
Interval 12.0 to 26.3
25.2 percentage of days under-immunized
Interval 16.0 to 34.5

SECONDARY outcome

Timeframe: 24-48 hours after the 6 month health supervision visit

Population: Proportion of parents with a highly-rated visit experience by study arm, defined as those who scored 90 or higher (out of 105) on the visit experience survey

Score on a 15-item parent-completed visit experience survey (minimum score 15; maximum score 105, with higher scores suggesting a higher rated visit experience)

SECONDARY outcome

Timeframe: Change post-intervention from pre-intervention

Population: Proportion in arm who rated barrier as significant (3-5 on a 1-5 scale, where 1=not at all significant and 5=very significant)

Provider-reported ratings of the significance of 3 barriers to the vaccine discussion: a) not having enough time to discuss parental vaccine concerns, b) not realizing until late in the visit that a parent had vaccine concerns, and c) not understanding a parent's specific vaccine concerns to be barriers pre- and post-intervention
