Hi Sue It may be worth just testing her blood to see 'where she's at' immunity wise, you can then offer her further vaccination if indicated. The question I would have to ask though is why does she keep failing to adhere to the course? Does she not understand the risks associated with BBV's? regards Glenn ~~~~~~~~~~~~~~~ Please remove this footer before replying.
