We aim to examine risk of acute hospitalization among MS patients up to 3 months following influenza infection and pandemic vaccination in a large population-based cohort consisting of 6755 MS patients using nationwide populationbased Norwegian registries. We applied the self-controlled case series (SCCS) method to estimate incidence rate ratios (IRRs) of acute hospitalization with MS diagnosis in various risk periods following a diagnosis of influenza infection or vaccination, compared with a background period [22] . In model III, the IRR of acute hospitalization among patients was estimated following a diagnosis of seasonal influenza infection in the period from 1st of January, 2008 through 15st May, 2014, excluding the pandemic season (from September 2009-May 2010).	./cache/cord-010786-w3kjc6so.txt	./txt/cord-010786-w3kjc6so.txt
