English to Russian Medical Medical (general) A Parent\'s Guide to Vaccination (Canadian Pediatric Society)

There is some evidence suggesting that infection in childhood might play a role in the development of this disease. There is no evidence that immunization causes MS or even ****flare-ups**** in a person with MS. In particular, hepatitis B and influenza vaccines have been shown to have no effect on symptoms or on the rate that symptoms progress in patients with MS. By contrast, influenza infection has been associated with ****flare-ups of MS****.

TIA!
