| 4 February 2010 | Amended | We changed a factual error in the 'plain language summary' that BCG caused tuberculosis. The corrected sentence reads "Bacillus Calmette‐Guérin (BCG) is a live attenuated bacterium used for immunization against tuberculosis, and is safe and effective for that purpose; it has also been licensed by the US FDA and other national regulatory agencies for use in superficial bladder‐cancer treatment." |
