Researchers at South Australia's Health and Medical Research Institute (SAHMRI) have made a groundbreaking discovery affecting our newborns.
A recent study has found that exposing babies to antibiotics could block the effects of common vaccinations for deadly diseases including Whooping Cough, Meningococcal, Tetanus, Pneumonia and Polio.
The antibiotics cause change to the gut bacteria microbiome in babies as they grow, altering the way the body reacts to vaccinations.
It wasn't found to be the case in adults when testing was done on mice.
Statistics show about 50 per cent of Australian babies are prescribed antibiotics by the time they turn one.
