No. The Public Health Service (PHS) recommends that all persons continue to be vaccinated according to current schedules. No evidence exist that cases of vCJD are related to the use of vaccines, and no cases of vCJD have ever been reported in the U.S.

In addition, there is no evidence that any vaccines harbor the BSE agent. As a result, PHS has no preference for using one licensed vaccine product over another based on the source of bovine-derived materials used in vaccine production.
