Tried-and-true vaccines are like plumbing or city infrastructure: Once established, it’s taken for granted and the true value can’t be intuited.

BCG, sadly, is not really in that category.

What's the issue with the BCG? My understanding was that it had been sucessful, is that a bit of a myth?

It’s not very effective, and it’s apparent efficacy is bizarrely variable.

Thanks, I had no idea. It was the standard when I was growing up in the UK.

It looks like it is no longer standard issue here.
