I also have a question. To work in any medical post in the UK you have to be vaccinated against Hep B. Does this mean that anyone who has been vaccinated will have antibodies in their blood and therefore may be identified here as a risk? Is is possible to tell the difference between someone who has been vaccinated and someone who has been exposed to the virus by other means? Should people who have been vaccinated carry evidence of it so that they can prove that they are not a risk? There are so many doctors here who have practiced in the UK, there must be a policy. All of you, thanks for th info. JJ
