At least 25 federal agencies have implemented a system to track religious exemption requests for mandated vaccines, according to a review of Federal Register notices by The Epoch Times. The agencies include the departments of Justice, Health and Human Services, Housing and Urban Development, Transportation, the Treasury, the Social Security Administration, the Federal Election Commission. The Heritage Foundation, a conservative group, earlier this week found that 19 agencies were either considering or have already implemented the tracking system. The group warned that the system may be a test pilot plan to monitor all federal workers.
