Summary

This study will collect information on the safety of BNT162b2 products for subjects who have been administered in a routine clinical practice from 05Mar2021 to 04Mar2027 in Korea, and will be conducted in accordance with the New Drug Re-Examination Guideline of the Ministry of Food and Drug Safety (MFDS).

Detailed description

This is an open-label, non-comparative, non-interventional, prospective, and multi-center study conducted in Korean health care centers by accredited physicians (investigator). The study population is Korean subjects who are scheduled for COVID-19 vaccination. BNT162b2 products will be administered according to the "Dosage and Administration" of the approved labeling. There is no visit or activity mandated by this study. The investigator will collect data from the subject's medical records and patient (subject) report outcome (PRO), and record the information on each subject's case report form (CRF). Pfizer Pharmaceuticals Korea will conclude a post-marketing surveillance agreement with an investigator site before performing the study. Investigators at the institution that sign the agreement should prepare the CRFs from all the subjects who this vaccine was administered to after the start date of the study. Each investigator will sequentially enroll all subjects to whom BNT162b2 products is prescribed for the first time according to the local product document and who agree to participate in this study by signing the data privacy statement used in place of the informed consent form until the total requested cases per center are collected for this study. An electronic diary will be used in this study to collect adverse events that occur after injection. Follow-up exams will be carried out from after the first injection to before the second injection, and from after the second injection to 28 days after the second injection. Those who received booster doses will be followed up for the 28 days from the date of the booster dose. For the follow-up adverse event CRF, either an application using the mobile phones of subjects or entry on a paper questionnaire may be selected. The CRF will be filled out every day after the first and second injections. If an application is used, it is automatically sent as an eCRF. If a paper questionnaire is used, the questionnaire filled out after the first injection is collected at the time of the visit for the second injection, and the questionnaires filled out after the second injection and booster dose are collected 28 days after the second injection and 28 days after the booster dose respectively by mail. To promote the collection of adverse events after injection, a reminder may be given by phone about entering the information and the collection of the CRF to subjects who gave consent beforehand. If it is difficult to record CRF due to the subject, the occurrence of adverse events can be confirmed by phone. Safety is the primary interest of this study, which will be assessed based on adverse events (AEs) that occur during 28 days from the date of the first, second and booster doses of BNT162b2.

Interventions

Type	Name	Description
BIOLOGICAL	Tozinameran 12 Years of age and older	BNT162b2 (purple cap) is administered with dilution, while BNT162b2 (grey cap) is administered without dilution. Both formulations are administered by intramuscular injection (IM) of 0.3 mL. According to the approved and authorized label, the recommended dose of BNT162b2 is a series of two doses (1 day 1 dose, 0.3mL each) 21 days apart and administered IM.
BIOLOGICAL	Tozinameran 5 to 11 Years of age	BNT162b2 (orange cap) is administered with dilution by intramuscular injection (IM) of 0.2mL. According to the approved and authorized label, the recommended dose of BNT126b2 is a series of two dose (1day 1dose, 0.2mL) 21days apart and administered IM. But, a third dose may be given at least 28 days after the second dose to individuals who are severely immunocompromised aged 5 to 11 years of age.
BIOLOGICAL	Tozinameran 6 months to 4 years of age	BNT162b2 (maroon cap) is administered with dilution by intramuscular injection (IM) of 0.2mL. According to the approved and authorized label, it is recommended that the recommended dose of BNT162b2 is administered by intramuscular injection (IM) twice (once a day, each 0.2mL) at least of 21 days apart, and Dose 3 at least 8 weeks later. Children who will turn from 4 years to 5 years of age between their doses in the vaccination course should receive their age-appropriate dose at the time of the vaccination and the interval between doses is determined by the child's age at the start of the vaccination course. The interchangeability of BNT162b2 with COVID-19 vaccines from other manufacturers to complete the vaccination course has not been established. BNT162b2 (6 months to 4 years of age) should be used only for infants and children 6 months to 4 years of age.
BIOLOGICAL	Riltozinameran 12 Years of age and older	The bivalent COVID-19 Vaccine for omicron (BA. 1) (grey cap) is administered by intramuscular injection (IM) of 0.3mL. There should be an interval of at least 3 months between administration of the bivalent COVID-19 Vaccine for omicron (BA. 1) and the last prior dose of a COVID-19 vaccine. The bivalent COVID-19 Vaccine for omicron (BA. 1) is only indicated for individuals who have previously received at least a primary vaccination course against COVID-19.
BIOLOGICAL	Famtozinameran 12 Years of age and older	The bivalent COVID-19 Vaccine for omicron (BA. 4-5) (grey cap) is administered by intramuscular injection (IM) of 0.3mL. There should be an interval of at least 3 months between administration of the bivalent COVID-19 Vaccine for omicron (BA. 4-5) and the last prior dose of a COVID-19 vaccine. The bivalent COVID-19 Vaccine for omicron (BA. 4-5) is only indicated for individuals who have previously received at least a primary vaccination course against COVID-19.
BIOLOGICAL	Famtozinameran 5 to 11 Years of age	The bivalent COVID-19 Vaccine for omicron (BA. 4-5) for 5 to 11 years of age (orange cap) is administered after dilution by intramuscular injection (IM) of 0.2mL. There should be an interval of at least 3 months between administration of the bivalent COVID-19 Vaccine for omicron (BA. 4-5) for 5 to 11 years of age and the last prior dose of a COVID-19 vaccine.
