Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is randomized, placebo-controlled, observer-blinded, multi-center study to assess safety, reactogenicity and immunogenicity of booster vaccination of a SARS-CoV-2 recombinant protein nanoparticle vaccine (GBP510) adjuvanted with AS03 in adults aged 19 years and older who received a primary series of vaccination or the 1st booster vaccination against COVID-19 approved in Korea.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to assess the safety, reactogenicity and immunogenicity of booster vaccination of a SARS-CoV-2 recombinant protein nanoparticle vaccine (GBP510).

(Cohort 1\~5) A total of approximately 550 adults will be divided into 5 cohorts based on primary series vaccines they received - ChAdOx1 nCOV-19, BNT162b2, mRNA-1273, Ad26.COV2.S and heterologous vaccination with ChAdOx1 nCOV-19 \& BNT162b2.

(Cohort 6\~7) A total of approximately 220 adults will be divided into 2 cohorts based on primary series \& 1st booster vaccines they received -mRNA vaccines (BNT162b2 or mRNA-1273) and at least more than a single dose of non-mRNA vaccines (ChAdOx1 nCOV-19, Ad26.COV2.S, and NVX-CoV2373)

The participants are then randomized at a ratio of 10:1 to either Test Group or Placebo Group. Participants will be subject to follow-up for 12 months after receiving a single booster dose of GBP510 adjuvanted with AS03.

Blood sampling for cell-mediated immunity will be undertaken on approximately 20% of the participants in each cohort, who are selected in advance in consideration of the randomization ratio between Test Group and Placebo Group.
