Devised at France’s legendary Pasteur Institute 100 years ago, the Bacillus Calmette-Guerin (BCG) vaccine is one of the world's oldest and most trusted immunisations.
Trials started in Cape Town, where BCG booster shots were administered to 250 healthcare workers, while another 250 received a dummy formula, or placebo.
“There are observations that this BCG vaccine does something to the immune system that we don't really understand,” Task founder Prof Andreas Diacon said. Children immunised with BCG tend to suffer less from respiratory illnesses, including asthma, he said.
