This letter will  constitute an opinion upon the legality of the sale by CEL-SCI
Corporation,  a Colorado corporation ("CEL-SCI"),  of shares of its common stock
having a maximum  value of  $50,000,000  all as referred to in the  Registration
Statement  on Form  S-3  filed  by  CEL-SCI  with the  Securities  and  Exchange
Commission.

We have  examined the Articles of  Incorporation,  the Bylaws and the minutes of
the  Board of  Directors  of  CEL-SCI  and the  applicable  laws of the State of
Colorado, and a copy of the Registration Statement.  In our opinion,  CEL-SCI is
authorized  to  issue  the  shares  of  stock  which  are  the  subject  of this
registration  statement and such shares,  when issued, will represent fully paid
and non-assessable shares of CEL-SCI's common stock.

Very truly yours,
