Cookies

Our servers deposit small text files called "cookies" on your hard drive when you visit Wyeth Sites. Cookies are used to store information. Wyeth Sites use two types of cookies: "session cookies" and "persistent cookies".

Session cookies are deposited for the length of your stay on the web site, and are deleted when you shut down your browser or turn off your computer. We use these cookies to collect aggregate statistical information about how visitors use our web sites, such as the pages they visit and the length of their visit. We use this information to improve the design and content of Wyeth Sites. We may share this information with our US parent, affiliates, joint venture partners and other third parties. In addition, we often use these cookies for security purposes to ensure only registered users are permitted access to certain Wyeth Sites.

Persistent cookies remain on your computer's hard drive until you delete them and can be re-read when you return to the web site that deposited them on your hard drive. If you register for a Wyeth Site (or a section of a Wyeth Site), we will deposit a persistent cookie on your hard drive to remember information you gave us when you registered (i.e., user name, password, language preference) so you do not have to re-enter it with each visit and to provide you with access to areas of Wyeth Sites limited to registered users. Generally, we will ask you whether a Wyeth Site may place a persistent cookie on your hard drive.

We are only able to access and read those cookies that we place, not those placed by third parties.

Most browsers are defaulted to accept and maintain cookies. To learn more about cookies, and how to specify your cookie preferences, please search for "cookie" in the "Help" portion of your browser. You can configure your browser to accept all cookies, reject all cookies, or notify you whenever a cookie is set. If you simply want to browse a Wyeth Site, you do not have to accept cookies. However, if you would like to register and log in to special areas of a Wyeth Site, you will need to re-set your browser to accept cookies, otherwise, navigation of those areas may be impaired.

Pixel Tags

To measure the effectiveness of, and/or traffic on, Wyeth Sites, we may use "pixel tags" (also called clear GIFs, web beacons, and web bugs) in conjunction with cookies. A pixel tag is a type of web page graphic, usually only 1x1 pixel in size, used to track the number of Wyeth Site users and their navigation through particular pages of our sites.

We sometimes include pixel tags in our HTML-formatted e-mail messages to determine which messages were opened and whether they were acted upon. You may render some pixel tags unusable by rejecting their associated cookies.

We do not use pixel tag technology to collect personal information.

IP Addresses

An Internet Protocol (IP) address is a number assigned to your computer by your Internet Service Provider (ISP) whenever you connect to the Internet. Like other web sites, Wyeth Sites may collect IP addresses to analyze aggregate information about the number of visitors to our sites and site usage. We do not link your computer's IP address with personal information you provide. Where permitted by law, Wyeth reserves the right to use IP addresses to identify individuals who threaten the security of a Wyeth Site, a service, or a Wyeth Site user

Clickstream

A "clickstream" reflects the specific web pages visited by an individual user and, importantly, the manner or traffic pattern by which a user moves from one web page to another. We track such information only within Wyeth Sites.

Clickstream data that we collect does not contain or reveal any personal information about the user, and we do not match that data with the personal information you provide.

LEAVING WYETH SITES

As a resource to Wyeth Site users, we may provide links to third-party web sites. We try to choose sites we believe are useful and meet our high standards. However, we do not guarantee the standards of every linked web site, nor are we responsible for the content of non-Wyeth Sites. Wyeth does not endorse linked third-party web sites. These links are provided for convenience and/or informational purposes only.

Please be aware that owners of third-party web sites, or advertisers on such sites, may collect personal information from you. This Policy does not cover the privacy practices of third-party web sites. We suggest that, when linking to a third-party web site, you first read the site's privacy policy before navigating that site.
