Welcome to the SYSVAC, a database of systematic reviews on vaccines and immunisation. These have been collated from other databases, so as to provide a more streamlined resource. References included in this database have been screened for inclusion on title/abstract only, not full text. No quality assessment has been conducted on those included.

The database linked above includes references from January 2010 to September 2014 only - older and more recent systematic reviews should now be included in the NITAG

Resource Centre database, hosted by WHO. You can access this resource at http://www.nitag-resource.org/.

You can search the old SYSVAC above. Enter your search terms into the box above and click 'search' to see the results. You can either enter one or multiple search terms. The search

terms will be combined with 'AND'.
