卡介苗可以诱导具有非特异性记忆特征的先天免疫系统的表观遗传变化,

英文摘要
Project Summary/ Abstract
BCG can induce epigenetic changes in the innate immune system with non-specific memory characteristics,
termed `trained immunity', associated with enhanced immune responses to heterologous infections and
vaccines. We hypothesize that the enhanced immunity induced by BCG vaccination will provide protection for
high-risk individuals against COVID-19 and other viral respiratory infections. This hypothesis will be assessed
by conducting a Phase II double blind, randomized, placebo (vehicle)-controlled clinical trial of BCG Tokyo
172-1 (BCG-Japan) vaccine for the prevention of COVID-19 in healthcare workers (HCWs at high-risk for
infection. BCG-Japan is one of the most potent formulations of BCG vaccine demonstrating relatively high
microbial viability and human innate immune activation, and offering robust protection against TB and multiple
off-target infections. This study will test the hypothesis that administration of BCG-Japan vaccine to HCWs at
high-risk for infection will enhance innate antiviral immunity to reduce the risk for SARS-CoV-2 .infection and/or
severity of COVID-19. Two thousand and eight hundred (2,800) eligible volunteer HCWs will be randomly
assigned to either a placebo vaccination or BCG-Japan, conducted at Brigham & Women's Hospital and up to
four additional clinical sites. Subjects will be monitored for two years with assessments for viral illness and
serological and molecular monitoring for SARS-CoV-2. A subset of subjects will be intensively studied using a
suite of systems biology analyses, which will be integrated with clinical data to gain insight into the impact of
BCG on human immunity in relation to SARS-CoV-2 infection and/or incidence or severity of COVID. Overall
this aspect will provide information regarding how BCG may reshape the human blood and nasal mucosal
compartments in a manner that may correlate with protection against SARS-CoV-2 infection and/or incidence
and severity of COVID.
