Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of Participants With Serious Adverse Events
Time Frame: From the day following 28 days after the final vaccination of COMIRNATY, If those who did not conducted the booster vaccination was 11 months, If booster vaccination was conducted, up to the day before booster vaccination.
A serious adverse event was any untoward medical occurrence resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening experience (immediate risk of dying); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; or congenital anomaly.
From the day following 28 days after the final vaccination of COMIRNATY, If those who did not conducted the booster vaccination was 11 months, If booster vaccination was conducted, up to the day before booster vaccination.
Proportion of Participants With Severe COVID-19
Time Frame: From the day following 28 days after the final vaccination of COMIRNATY, If those who did not conducted the booster vaccination was 11 months, If booster vaccination was conducted, up to the day before booster vaccination.

By using the information on COVID-19 entered in the CRF submitted by the physician, participants who were considered to be in a severe condition were identified and the number and proportion of the participants were tabulated with reference to the severity classification in the Guidance for Treatment of Novel Coronavirus Infection (COVID-19).

Participants with severe COVID-19 were defined as any of the following actions taken during the period from disease onset to the outcome date: admission to an ICU; use of mechanical ventilation; or use of ECMO.

From the day following 28 days after the final vaccination of COMIRNATY, If those who did not conducted the booster vaccination was 11 months, If booster vaccination was conducted, up to the day before booster vaccination.
Proportion of Participants With Serious Adverse Reactions
Time Frame: From the day following 28 days after the final vaccination of COMIRNATY, If those who did not conducted the booster vaccination was 11 months, If booster vaccination was conducted, up to the day before booster vaccination.
A serious adverse reaction was any untoward medical occurrence attributed to COMIRNATY resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening experience (immediate risk of dying); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; or congenital anomaly. Relatedness to COMIRNATY was assessed by the physician.
From the day following 28 days after the final vaccination of COMIRNATY, If those who did not conducted the booster vaccination was 11 months, If booster vaccination was conducted, up to the day before booster vaccination.
Number of Participants With Serious Adverse Events After Booster Vaccination
