Efficacy and Safety of Oral Lactobacillus Plantarum GUANKE (CGMCC NO.21720) in Enhancement of Antibody Level After SARS-CoV-2 Vaccination (Trial 1)

SARS-CoV-2 Clinical Trial

Official title:
Efficacy and Safety of Oral Lactobacillus Plantarum GUANKE (CGMCC NO.21720) in Enhancement of Antibody Level After SARS-CoV-2 Vaccination: A Prospective, Randomized, Double-blind, Placebo-Controlled Trial (Trial 1)

Clinical Trial Summary

Preliminarily explore the effect of oral probiotics in SARS-CoV-2 serum neutralizing antibody titer level and T cell response level (spot formation cell counting). Provide a reference for determining the appropriate oral regimen. Provide necessary parameters for estimating the sample size of confirmatory clinical trial.

Clinical Trial Description

In selected communities or assigned clinical trial institutions, participants who had completed two doses of SARS-CoV-2 vaccination will be invited in this study. Informed consent form will give to potential participants with well explained of trial contents during baseline. Participants who gave their signed informed consent form will be blocked randomized in a 1:1 ratio to intervention group or placebo control group. ;
