Hmm, that's a rather confusing thing to have been told. I mean, does a "high" immune system mean that she already had some innate immunity to TB (some people do), or that she made a "high" response to the imm???

In any event, it may be up to ~6 wks before a blister appears, so give it some time. If nothing at all appears after 8 weeks, I think I'd be inclined to make further enquiries.

I agree with Buggie that the extent of the scar can vary hugely person to person, so it's not an accurate indicator of induced immunity on an individual basis. Although if no local reaction develops at all, this could (possibly, not always) indicate that the immune response to the vaccine has been insufficient to give significant immunity. But whether or not re-vaccination would be appropriate is unclear, as some sources suggest that re-vaccination does not incur a more potent or significant immune response. I would speak to the imms nurse or phone NHS direct (0845 46 47) if you're unsure. xx
