From chickenpox?
DCs aged 7 and nearly 5 haven't had chickenpox yet. Despite it being rife through nursery/school/friends several times over the years.
DH had shingles as a young adult before the DCs were born.
As I understand it, DH will continue to host the shingles virus forever. Could the DCs lifelong exposure to DH mean they might be immune to Chickenpox and Shingles?
Or is that a totally dumb-arse assumption???
