OVID MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R) were used as the searching resources to include the most recent published works that may not yet have been indexed. Truncation (*) was used for the search term ‘vaccin *’ to include terms for vaccine, vaccines and vaccination, which in practice searches brought up additional results. Two overlaps were identified between MEDLINE and EMBASE. Both results identified in Cochrane reviews overlapped with MEDLINE but were not present in EMBASE.
