Hi folks
I am reviewing a blood borne viral disease policy ( I'm NHS based)and
would like some advice. Currently we offer a primary course of hepatitis
B vaccine, check immunity levels after eight weeks and if >100 give a
single booster at five years. Individuals who have levels of 10-100 are
boosted and rechecked. If >100 then followed up as above.
I have heared that there are concerns that at this level (10-100) there
may be an infection risk due to previous or current infection and that
testing for hepatitis B antigens or core antibodies may be appropriate
for those undertaking exposure prone procedures. Should we review the
small but significant group of staff who seem unable to reach the magic
figure >100.
Also in staff members with no history of vaccination or who have not
converted, undertaking exposure prone procedures, we require evidence of
hepatitis B surface antigen status. There seem to be mixed messages as
to how frequently this should be reassessed. Should it be ever six
months or every twelve or any advances?
I don't seem to be able to find very recent guidelines- have I missed
something?
Looking forward to your answers
Sandy Townsend
