Safety Study of GSK Biologicals' Rotavirus Vaccine (Rotarix®) Administered to Children Aged <1 Year in the United States

August 2, 2018 updated by: GlaxoSmithKline

Safety Study of GSK Biologicals' Rotarix® (Rotavirus Vaccine, Live, Oral) Administered to a Birth Cohort in United States Health Insurance Plans

This observational cohort study, conducted through two existing large administrative health databases in the US (outside the Vaccine Safety Datalink) is planned to confirm the safety profile regarding lack of any association of intussusception with Rotarix within 60 days of vaccination in a real life setting (routine use) in the US. This study will also include monitoring of Kawasaki disease, convulsions, hospitalizations due to acute lower respiratory tract infections and all-cause deaths within 60-days of vaccination.

This study involves three cohorts, one exposed and two control cohorts: infants who receive Rotarix (Exposed cohort) and infants who receive IPV vaccination (Unexposed cohort A and B).

This is a combined prospective and retrospective cohort study. Prospective component of the study identifies and compares study outcomes following Rotarix and IPV vaccination in the Exposed cohort and Unexposed cohort A, respectively.

Retrospective component of the study identifies and compares study outcomes following IPV vaccination in the Unexposed cohort B.

HRV cohort
HRV (Human Rotavirus) cohort consisted of infants aged less than 1 year, enrolled in the participating health insurance plans within 30 days of birth and who received at least one dose of Rotarix vaccination as part of their normal health care (with no previous dose of RotaTeq prior to or concurrent with the first Rotarix vaccination).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence Rates of Intussusceptions (IS) Among the HRV Cohort and Comparator Cohorts
Time Frame: 60 days following each vaccination
Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).
60 days following each vaccination
Incidence Rates of IS Among the HRV Cohort and Comparator Cohorts
Time Frame: 7 days following each vaccination
Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).
7 days following each vaccination
Incidence Rates of IS Among the HRV Cohort and Comparator Cohorts
Time Frame: 30 days following each vaccination
Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period.

30 days following each vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
