We matched case patients with ITP to one or two control patients with other diseases by institution, hospital visit timing, sex, and age. These limited data suggest no significant ITP risk following vaccinations or simultaneous vaccination in any age group, including infants. In this case-control study, we aimed to determine the ITP risk after live, inactivated and simultaneous vaccination in Japan. To measure this exposure, participating physicians who treated case (ITP) and control (other diseases) patients completed questionnaires covering retrospective information on vaccination history and other characteristics. Participating physicians matched controls with case patients by the institution, timing of hospital visit (within a 1-month difference), sex and age.	./cache/cord-011245-nkr0998x.txt	./txt/cord-011245-nkr0998x.txt
