Hi I'm Helen and I'm kinda new here,

I have MS and my 11 year old son is due to start high school next year in Melbourne Australia and will be offered a Hepatitis B vaccine. I have heard this can increase his risk of developing MS. I'm really not sure whether I should have him vaccinated or not given that his risk is already increased by having a mother with MS. If anyone has any further information, or links to further info or studies, about this I would be very grateful if they can let me know.
I'd be really interested to hear about other peoples experiences on this topic as well.
