Australia trialing TB vaccine against COVID-19

TB vaccine trialed on virus

Researchers in Australia have fast-tracked large-scale human testing to see if a long-used vaccine to prevent tuberculosis can work on COVID-19. 

Agence France-Presse reported the vaccine will be given to 4,000 healthcare workers in hospitals across Australia in a study by researchers at the Murdoch Children's Research Institute in Melbourne.

"Although originally developed against tuberculosis, and still given to over 130 million babies annually for that purpose, BCG also boosts humans' 'frontline' immunity, training it to respond to germs with greater intensity," they said in a statement.

"We hope to see a reduction in the prevalence and severity of COVID-19 symptoms in healthcare workers receiving the BCG vaccination," lead researcher Nigel Curtis told AFP.

The 4,000 subjects will be enrolled in the trial in a matter of weeks. 

Similar trials are underway in Europe.
