2022年7月3日 更新者:Yangfeng Wu、Peking University
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)
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.
