This new site from SmithKline Beecham, a "virtual gateway into the world of vaccinology," offers a host of resources on vaccination and vaccine preventable diseases. These resources are organized in three principle sections: Disease, Bio News, and Links. The first and largest section contains various reference resources for ten different diseases or disease groups, which are listed in four columns: disease, virus, epidemiology, and prevention. Although a public site, much of this information is aimed at physicians, health professionals, or other informed users. The Bio News section offers a selection of recent and archived scientific published data from peer-reviewed journals, a select list of links for breaking health news, and recent SmithKline Beecham vaccine press releases. A collection of related annotated links, sorted by country, rounds out the site. An additional site for registered medical professionals only is also available, and these users may log on via the public site. Please note that the site authors indicate that "This site is not intended for US audiences."
