The purpose of this clinical protocol is to learn about the safety, tolerability, and immunogenicity of new BNT162b2 RNA-based vaccine candidates targeting new variants of SARS-CoV-2 in healthy people.
Substudy A:
-
This study will evaluate the safety, tolerability, and immunogenicity of BNT162b2 (Omi XBB.1.5) given as a single 30 µg dose,
- in people who are 12 years of age and older,
- who previously received at least 3 doses of a US-authorized mRNA COVID-19 vaccine, with the most recent dose being an Omicron BA.4/BA.5-adapted bivalent vaccine received at least 150 days before the study vaccination (Visit 1).
- The study is about 6 months long for each participant.
- Participants will have at least 5 visits to the clinic.
- At each clinic visit a blood sample will be taken.
- At least 1 nasal swab will taken.
Substudy B:
-
This study will evaluate the safety, tolerability, and immunogenicity of BNT162b2 (Omi XBB.1.5) given as a single 30 µg dose,
- in people who are 12 years of age and older,
- who are COVID-19 vaccine-naïve
- who have had any positive SARS-CoV-2 test result >28 days before study vaccine administration.
- The study is about 6 months long for each participant.
- Participants will have at least 5 visits to the clinic.
- At each clinic visit a blood sample will be taken.
- At least 1 nasal swab will taken.
