Brief summary

Post-marketing study, Chotor study of COMIRNATY vaccenees followed for 11months. Serious adverse events and COVID-19 observed during the follow-up period will be collected, and the long-term safety of this product will be assessed.

Detailed description

The healthcare professionals who are vaccinated with this product early after the marketing approval of this product (participants in the Investigation of Health Status of Recipients Vaccinated First conducted by the Science Research Group of the Ministry of Health, Labour and Welfare) will be followed for 11 months from the day following 28 days after the final vaccination of the initial immunization with this product (end date of observation period in Investigation of Health Status of Recipients Vaccinated First) to 12 months after the final vaccination of the initial immunization with this product, information on serious adverse events and COVID-19 observed during the follow-up period will be collected. If booster vaccination isn't conducted, the long-term safety after the initial immunization of this product during the follow-up period will be assessed. If booster vaccination is conducted, the long-term safety after the initial immunization of this product up to the day before booster vaccination will be confirmed, and information on serious adverse events and COVID-19 will be continuously obtained after booster vaccination.

Interventions

BIOLOGICALBNT162b2

Comirnaty is administered intramuscularly after dilution as a course of 2 doses (0.3 mL each). It is recommended to administer the second dose 3 weeks after the first dose. Individuals 16 years of age and older.

Proportion of Participants With Serious Adverse EventsFrom 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.
Proportion of Participants With Severe COVID-19From 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.
Proportion of Participants With Serious Adverse ReactionsFrom 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.
