This is partly medical of course, but also might be answered by anyone who has recently had trouble sourcing hepatitis A and B vaccines.
Apparently there's a global shortage. I cannot get it anywhere in France (we're in Paris). My son, 18 yrs old, is about to fly off to China and it had not occurred to me that we may be unable to vaccinate him properly.
Any ideas about how worried I should be, what alternatives we may have for finding any vaccines (eg hopping over to London and going privately), and failing that, what kind of precautions he should take whilst out there?
Thanks!
