<p>Deferral policies are school-dependent. Some will allow you to defer; some won 't.</p>
<p>However, I believe that you must report on your AMCAS that you’ve been accepted to a DO school. (You have to report any medical school–and it doesn’t specify MD-only–acceptances you’ve received in the past.) Having a med school acceptance which you didn’t follow thru on or didn’t accept will hurt your chances (a lot) in the next admission cycle.</p>
