BCG and COVID-19

The BCG vaccine is a crucial tool for protecting babies and young children in high burden countries from TB, which killed 1.5 million people in 2019 and caused 10 million people to fall sick. Recent media reports indicating that BCG, the only licensed vaccine to protect again TB, may be protective against COVID-19 have led to new interest in this century-old vaccine. However, BCG’s ability to protect against COVID-19 infection or disease has not yet been tested in rigorous, prospective, randomized, controlled clinical trials. Such trials are now underway to study the effects of BCG in healthcare workers and others at high risk of COVID-19. Decisions on use of BCG to protect against COVID-19 should await these results and adequate supplies of BCG should be preserved to protect infants and children in high burden countries from TB.

Resources about TB
and TB Vaccine R&D

  • TB Vaccine Development Pathway, developed by IAVI and TBVI, is a tool that provides a structured development path and gating criteria for TB vaccine candidates. It also describes the different functions and capabilities required to advance a candidate TB vaccine to its next stage of development.
  • Global Tuberculosis Report, published by the WHO, provides a comprehensive and up-to-date assessment of the TB epidemic, and of progress in prevention, diagnosis and treatment of the disease at global, regional and country levels. The report is updated annually.
  • Global Investments in Tuberculosis Research and Development: Past, Present, and Future is a policy paper developed by WHO in collaboration with civil society groups, academia, and product development partnerships to articulate the research and funding needs to end TB.
  • TB Research Investments Provide Returns in Combating Both TB and COVID-19 is a policy brief published by Treatment Action Group (TAG) that explores the impact of COVID-19 on TB research and development (R&D), and how tools, concepts, capacity, and infrastructure established through years of public and donor investments in TB R&D have informed and jump-started COVID-19 research and responses.

Resources for Advocacy and Community Engagement

  • The Urgent Need for New TB Vaccines is a fact sheet developed by WGNV that highlights the importance of new TB vaccines, and the strategy and funding needed to develop them.
  • Vital Role for of Research for TB Elimination is a briefing document from TAG, WGNV and several other partners that provides information on TB R&D and its centrality to universal health coverage in preparation for the United National High Level Meeting on TB.
  • Report on Tuberculosis Research Funding Trends, published annually by TAG, tracks how much public, private, philanthropic, and multilateral institutions spend on TB research and development (R&D) across six areas of research: basic science, diagnostics, drugs vaccines, operational research, and infrastructure/unspecified projects.
  • Good Participatory Practice Guidelines for TB Vaccine Researchpublished by Aeras, is a user- friendly framework that defines specific standards and key elements needed for creating effective partnerships with stakeholders throughout the entire research process. Contact us if you are interested in obtaining copies of the GPP guidelines for TB vaccine research.
  • Frequently Asked Questions on TB Vaccine Research, published by IAVI, is a fact sheet that provides information and answers to commonly asked questions about TB vaccine research.
  • Myths and Facts about TB Vaccine Research, by IAVI, is a fact sheet that responds to some common misconceptions about vaccine research.
  • Tuberculosis Vaccines and Clinical Trialspublished by IAVI, provides information about TB, vaccines, and clinical trials in an illustrative and easy to understand booklet.
  • Being Part of Tuberculosis Vaccine Clinical Trials is a speaking book published by Books of Hope in collaboration with Aeras, that provides potential clinical trial participants with information about tuberculosis and what is involved in participating in a clinical trial. The information is in both English and Afrikaans. Hard copies of the speaking book are available on request. Contact us if you are interested in obtaining copies of the speaking book.
