A new study suggests people in the early stages of multiple sclerosis may be helped by a vaccine used in some parts of the world to prevent tuberculosis.
The study from Italy involved 73 people who had shown possible signs of MS, like numbness or problems with vision and balance, and who also had an MRI that suggested the early stages of the disease.
About half received a live vaccine that's used in other countries to prevent tuberculosis.
After five years, 58% of those vaccinated were free of MS compared to 30% of those who were not vaccinated.
The key may be the exposure to the vaccine's live virus.
This study is from researchers at Sapienza University, and is published in "Neurology", medical journal of the American academy of Neurology.
