The BCG Vaccine is a vaccine containing bacillus Calmette-Guerin (BCG), an attenuated strain of Mycobacterium bovis, with non-specific immunoadjuvant and immunotherapeutic activities. Although the mechanism of its anti-tumor activity is unclear, immunization with BCG vaccine likely activates a Th1 cytokine response that includes the induction of interferon. Vaccination with BCG vaccine may be immunoprotective against infection with Mycobacterium tuberculosis.
COVID-19 continues to wreak havoc globally, with over one million deaths to date. Yet what if an existing vaccine could make COVID-19 less deadly? A study just published put the theory to test, with promising results.
Researchers from Mayo Clinic, United States of America, have reviewed the immunity developed against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease.
A largescale global trial designed to test the theory that the widely-used BCG vaccine could help protect against COVID-19 will soon recruit healthcare staff and care home workers in the UK.
While scientists race to develop and test a vaccine effective against SARS-CoV-2, the virus that causes COVID-19, recent studies have indicated that countries with widespread BCG vaccination appear to be weathering the pandemic better than their counterparts.
In a new study published on the preprint server medRxiv, researchers from Laval University and McGill University in Canada reviewed evidence from 18 relevant studies on a possible interaction between influenza vaccines on non-influenza respiratory disease (NIRD).
The BCG vaccine has a broad, stimulating effect on the immune system. This gives it an effective preventive action against various infections - possibly also against COVID-19. New studies are investigating that.
. A new study explores whether and how the practice of routine BCG vaccination of infants may have curbed the initial spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Japan. The research is published in the Journal of Infection.
A tuberculosis vaccine administered during the past 15 years is associated with significantly improved COVID-19 outcomes, according to a new study published in Vaccines.
The BCG vaccine, a vaccine originally made against tuberculosis, has a general stimulating effect on the immune system and is therefore effective against multiple infectious diseases - possibly also against COVID-19.
In a recent medRxiv preprint research paper, scientists from India analyzed twenty European countries and showed that the prevalence of exposure to Mycobacterium spp. (which includes BCG vaccine) is consistently negatively correlated with coronavirus disease (COVID-19) infections.
One of the emerging questions about the coronavirus that scientists are working to understand is why developing countries are showing markedly lower rates of mortality in COVID-19 cases than expected.
A tuberculosis vaccine developed 100 years ago also makes vaccinated persons less susceptible to other infections. While this effect has been recognized for a long time, it is not known what causes it.
As the world grapples with the coronavirus disease (COVID-19) pandemic, scientists race to develop an effective vaccine to protect against the deadly SARS-CoV-2 virus. While potential vaccines are still being developed and tested, researchers propose that existing vaccines could give the immune system a temporary boost to ward off infection.
Professor David Levine from the University of California, Berkeley, says a study of people in Spain and Italy has provided a “shred of evidence” that the BCG vaccination may protect against coronavirus disease 2019 (COVID-19).
An A$10 million grant from the Bill & Melinda Gates Foundation will allow the Murdoch Children's Research Institute's clinical trial of the BCG vaccine against COVID-19 to extend to 10,000 healthcare workers across Australia, Spain and The Netherlands.
A new paper published on the preprint server medRxiv in April 2020 challenges the hypothesis that BCG vaccination confers some degree of protection against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes the pneumonic illness COVID-19.
The association between BCG (Bacillus Calmette-Guérin) vaccination and its purported beneficial effect on COVID-19 transmission/mortality rates was challenged in an expert appraisal of Diamond Princess cruise ship data. At the same time, cross-national differences previously reported were shown to be flawed, reports a new medRxiv study.
From the plagues of medieval Europe to the influenza pandemic of 1918, the specter of the next public health disaster has gripped the minds of scientists, captivated the imaginations of writers and vexed conspiracy theorists.
All over the world, except in China, the place where it all began, the COVID-19 pandemic is making its relentless way through the population. So far, it has caused nearly 34,000 deaths – and the situation in the US is still worsening with over 142,000 cases and 2,489 deaths. In Australia, the number of cases has climbed to 4,093, with 16 fatalities.
Professor Kathryn North AC, Director of the Murdoch Children's Research Institute in Melbourne, Australia, has announced its infectious disease researchers are preparing to roll-out a multi-center randomized controlled clinical trial of the BCG vaccine against COVID-19.
