There seems to be conflicting issues in regard to Hep B and also BCG
It would be good if someone would come on board with what is needed and also how you convince Occ Health and any other body you ask.
The response I have had is you have had HepB & boosters so there is no need to have any more

BCG vaccination is rarely given to anyone over the age of 16 - and never over the age of 35, because it doesn't work very well in adults. It is, however, given to adults aged between 16 and 35 who are at risk of TB through their work, such as some healthcare workers.
