Safety Study of GSK Biologicals' Rotavirus Vaccine (Rotarix®) Administered to Children Aged <1 Year in the United States
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).
|
Review of two health insurance databases in the US to determine the safety outcomes among infants who have received Rotarix or IPV vaccination.
|
Concurrent Control cohort
Concurrent control cohort consisted of infants aged less than 1 year, enrolled in the participating health insurance plans, who were contemporaneous with the Rotarix vaccinees and who received at least one dose of IPV (Inactivated Poliovirus vaccine) with or without RotaTeq vaccination (with no previous dose of Rotarix prior to or concurrent with the first IPV vaccination).

|
Recent Historical Control cohort
Recent historical control cohort consisted of infants aged less than 1 year of age, enrolled in participating health insurance plans, vaccinated with at least one dose of IPV (Inactivated Poliovirus vaccine) between 1 January 2004 (OptumInsight) or 1 January 2006 (HealthCore) and 31 July 2008 and who did not receive any dose of rotavirus vaccination during the study period.

Primary Outcome Measures
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).
