Brief Summary:
The purpose of the study is to assess the long-term safety profile of Ad26.ZEBOV and MVA-BN-Filo in participants previously exposed to these vaccines in Phase 1, 2, or 3 clinical studies.

Condition or disease Intervention/treatment Phase
Hemorrhagic Fever, Ebola Biological: Ad26.ZEBOV Biological: MVA-BN-Filo Phase 3

Detailed Description:
This is a multi-country, prospective, long-term clinical safety study for collection of serious adverse events and pregnancy outcomes following administration of Ad26.ZEBOV and/or MVA-BN-Filo vaccines among participants who were enrolled in Phase 1, 2 or 3 clinical studies. The safety data will be collected in 3 cohorts; Cohort 1- adult and pediatric participants that received Ad26.ZEBOV and/or MVA-BN-Filo in Phase 1, 2 or 3 clinical studies (adults, adolescents and children), Cohort 2- Female participants who became pregnant with estimated conception within 28 days after vaccination with MVA-BN-Filo or within 3 months after vaccination with Ad26.ZEBOV will be followed to the end of their pregnancy for pregnancy outcomes (Cohort 2). After the end of pregnancy, female participants will continue to be followed in Cohort 1. Cohort 3 - children born to female participants exposed to Ad26.ZEBOV and/or MVA-BN-Filo who became pregnant with estimated conception within 28 days after vaccination with MVA-BN-Filo or within 3 months after vaccination with Ad26.ZEBOV. Safety data will be collected on all consenting participants.

Arm Intervention/treatment
Experimental: Exposed to Ad26.ZEBOV and/or MVA-BN Filo
Safety Data will be collected from participants who received Ad26.ZEBOV and/or MVA-BN-Filo in Phase 1, 2 or 3 clinical studies in 6-month intervals up to 60 months after prime vaccination, including the duration in the participant's original study (Cohort 1). Female participants who became pregnant with estimated conception within 28 days after vaccination with MVA-BN-Filo or within 3 months after vaccination with Ad26.ZEBOV will be followed to the end of their pregnancy for pregnancy outcomes (Cohort 2). After the end of pregnancy, female participants will continue to be followed in Cohort 1. Safety Data for live born children to female participants will be followed up to 60 months after birth (Cohort 3).
Biological: Ad26.ZEBOV
No vaccine will be administered in the current study. Safety data will be collected from participants who were previously exposed to Ad26.ZEBOV vaccine in Phase 1, 2, or 3 clinical studies up to 60 months and also safety data will be collected from live born children to female participants up to 60 months after birth.

Biological: MVA-BN-Filo
No vaccine will be administered in the current study. Safety data will be collected from participants who were previously exposed to MVA-BN-Filo vaccine in Phase 1, 2, or 3 clinical studies up to 60 months and also safety data will be collected from live born children to female participants up to 60 months after birth.

  3. Percentage of pregnancies (with estimated conception within 28 days after vaccination with MVA-BN-Filo or within 3 months after vaccination with Ad26.ZEBOV) by pregnancy outcome [ Time Frame: up to 3 months after vaccination ]
  4. Percentage of live-born children from a pregnancy with estimated conception within 28 days after vaccination with MVA-BN-Filo or within 3 months after vaccination with Ad26.ZEBOV [ Time Frame: up to 3 months after vaccination ]
  5. Percentage of serious adverse events in children born from a pregnancy with estimated conception within 28 days after vaccination with MVA-BN-Filo or within 3 months after vaccination with Ad26.ZEBOV [ Time Frame: Up to 60 months after birth in children born from an eligible pregnancy (with estimated conception within 28 days after vaccination with MVA-BN-Filo or within 3 months after vaccination with Ad26.ZEBOV) ]
