I've seen the UO's administration's announcement about vaccine requirements in the Oregon press in the last 24 hours.  

University of Oregon, Western Oregon University will require proof of COVID-19 vaccination

I couldn't find an answer to two questions:

1) Why doesn't the Board of Trustees have to make or approve this decision rather than university administrators overseen by the Board of Trustees?

2) Has the Board of Trustees approved the announced apparent decision?

3) If the UO mandate is put into effect, will the Board of Trustees mandate that UO must afford students solely remote access to the on-campus courses, including remote transmission of course meetings and access to course work?

4) If the UO mandate is put into effect, will the Board of Trustees mandate that UO employees who decline these vaccines must be allowed to keep their jobs and work remotely off-campus? 

5) While the Board has "delegated policy authority", does the Board acknowledge it has the authority to reverse this action?
