VAXZEVRIA Japan Post-Marketing Surveillance (PMS) for the Subjects With Underlying Disease at High-risk for Worsening COVID-19

Study Overview
=================
Brief Summary
-----------------
To provide more information on safety profile of VAXZEVRIA in Japanese subjects, specific drug use result study in subjects with underling disease at higher risk of worsening COVID-19 is planned as an additional pharmacovigilance plan. The present study aims to collect information on adverse drug reactions or COVID-19 infection after VAXZEVRIA vaccination and to evaluate the safety of this vaccine.

Detailed Description
-----------------
To provide more information on safety profile of VAXZEVRIA in Japanese subjects, specific drug use result study in subjects with underling disease at higher risk of worsening COVID-19 is planned as an additional pharmacovigilance plan. The present study aims to collect information on adverse drug reactions (local/systemic reactions), adverse events (including Shock/ Anaphylaxis, Thrombosis in combination with thrombocytopenia, Immune-mediated neurological conditions ,Vaccine-associated enhanced disease(VAED) including Vaccine-associated enhanced respiratory disease(VAERD) and Thrombosis) or COVID-19 infection after VAXZEVRIA vaccination and to evaluate the safety of this vaccine

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of adverse drug reactions, its incidence (%) (number of adverse drug reaction/number of eligible safety analysis population) will be calculated by preferred term (PT). | Adverse events that the investigator could not deny the causal relationship with VAXZEVRIA will be treated as adverse drug reactions. Number of adverse drug reactions, its incidence (%) (number of adverse drug reaction/number of eligible safety analysis population) will be calculated by preferred term (PT). | from the first vaccination date to 28 days after the second vaccination date | 
| Number of local/systemic reactions and its incidence (%) will be calculated for each reaction and also by grade. Ad hoc analysis might be performed as necessary. | Local/systemic reactions recorded in health observation diary by subjects and entered by the investigator in eCRF will be treated as specific adverse events and number of local/systemic reactions and its incidence (%) will be calculated for each reaction and also by grade. Ad hoc analysis might be performed as necessary. | each vaccination day (Day 1) to Day 8 | 
| Number of the subjects considered to be severe case of COVID-19 and its incidence (%) will be calculated. The subject who required a hospitalization in intensive care unit or use of respirator will be defined as a severe case. | Number of the subjects considered to be severe case of COVID-19 and its incidence (%) will be calculated. The subject who required a hospitalization in intensive care unit or use of respirator will be defined as a severe case based on the severity classification reference of A guide for front-line healthcare workers (MHLW, 2020). Ad hoc analysis might be performed as necessary. | from the first vaccination date to 28 days after the second vaccination date |
