The vaccine was designed to stop tuberculosis, but there is some evidence that it can protect against other infections as well

But while millions of people in the UK will have had the BCG vaccine as a child, it is believed that they should be vaccinated again to benefit from it

Vaccines are designed to train the immune system in a very targeted way that leaves lasting protection against a particular infection

But this process also causes significant changes in the immune system It seems to increase the response to other infections and scientists are hoping it could even give our bodies an advantage against the coronavirus

« This could be of major importance globally, » Professor John Campbell of the University of Exeter School of Medicine told the BBC

« While we don’t think [the protection] will be specific to Covid, it has the potential to gain several years for the Covid vaccines to pass and perhaps other treatments to be developed »

The UK trial is part of the international Brace study, which is also taking place in Australia, the Netherlands, Spain and Brazil, recruiting 10,000 people in total

It will focus on health and care workers, as they are more likely to be exposed to the coronavirus, so researchers will know more quickly if the vaccine is working

Sam Hilton, a general practitioner from Exeter, is participating in the trials because, as a doctor, he is more at risk of catching Covid

« There is a pretty good theory that BCG could make you less likely to suffer when you get Covid, » he told the BBC

« So I consider it possible for me to protect myself a little, which means that I am more likely to come to work this winter »

Dr Tedros Adhanom Ghebreyesus, Director General of the World Health Organization, is one of the authors of a Lancet article claiming that the BCG vaccine has the potential to « close the gap before a disease specific vaccine is not developed ”

« It would be an important tool in the response to Covid-19 and future pandemics, » says the article

Any improved resilience to Covid is expected to diminish, meaning people who were immunized with BCG as children will no longer have protection BCG is no longer used in the UK since 2005 because tuberculosis levels are so low

In addition, the vaccine will not train the immune system to produce the antibodies and specialized white blood cells that recognize and fight the coronavirus

The main objective remains a vaccine that specifically targets the coronavirus Ten of these vaccines are in the final phase of clinical research, including the one developed at the University of Oxford

Professor Andrew Pollard, of the Oxford Vaccine Group, told the BBC: « The way most vaccines work is by producing a very specific immune response against the germ you are trying to prevent

« But to get a good immune response there is also a rather non-specific ‘swelling’ of the immune response which changes the way the immune system is able to respond in the future

« The problem we have today is that I can’t tell you what you might do with other vaccines to try and improve your ability to respond to coronavirus because we don’t have any evidence at all «
