I didn't know what BCG is, so I looked it up. It's not mandatory any more here in Germany (since 1998) and only used for at risk people. Interestingly, it was used in the Basque Province of Spain till 2013 - might be interesting too see whether there is a difference now between this part of Spain and others...

Hello,
I didn't know about BCG either. I also had to look it up. That article from The Scientist (referred to in my comment above) is quite interesting. It seems BCG does offer protection against a variety of respiratory illnesses and protection lasts for many years. The information about the Basque Province is interesting and may help to provide insight in the future.
Thank you for your comment. I really do enjoy feedback.
Regards,
AG
