Immunization Safety Review

The Institute of Medicine's Immunization Safety Review Committee will hold a
workshop on the hypothesized relationship between thimerosal and specific
neurodevelopmental disorders on July 16-18, 2001 in Boston, Massachusetts. As
part of the committee's data gathering activities, we are seeking input on the
following:

1) Information on specific adverse outcomes that may be related to thimerosal
exposure.
2) Biological mechanisms that explain the hypothesized relationship between
adverse outcomes and thimerosal exposure.

We welcome information such as original articles (or citations), suggestions of
key researchers with expertise on this issue, and other types of information.
Please note that the National  Academy of Sciences' complies with Section 15 of
the Federal Advisory Committee Act (FACA), and therefore, all materials that are
distributed to the committee will be submitted to a public access file.

Thank you in advance for your assistance on this matter. Please send your
materials to us by Monday, May 14 via email (imsafety@nas.edu), fax
(202-334-2939), or by mail to
