         Re:      Registration Statement On Form S-8

Gentlemen:

I have acted as counsel to GeneThera, Inc. (the "Company") in connection with
the filing on or about July 31, 2006 of its registration statement on Form S-8
(the "Registration Statement") under the Securities Act of 1933 (the "Act") and
the rules and regulations promulgated thereunder (the "Rules and Regulations").
The Registration Statement relates to Six Million (6,000,000) shares of the
common stock, par value $0.001 per share, of the Company (the "Company Stock"),
which may be issued to eligible participants in the Consultant and Employee
Stock Compensation Plan (the "Plan") of the Company. The Plan is not subject to
the requirements of the Employee Retirement Income Security Act of 1974, as
amended ("ERISA").

This opinion, given as of the date hereof, is based upon facts and conditions
presently known and laws and regulations presently in effect, and is being
delivered pursuant to Item 601 of Regulation S-B under the Act.

As counsel to the Company and in rendering this opinion, I have examined the
Plan documents and other related written documentation as I have deemed
necessary or appropriate to provide the opinion on the basis set forth below. In
my examination, I have assumed the conformity to original documents submitted to
me as photo static copies, the genuineness of all signatures and the taking of
all required corporate action in relation with the Plan.

Based upon the foregoing, and subject to the qualifications set forth below, I
am of the opinion that the Shares, if issued and sold as described in the
Registration Statement (provided that at least par value is paid for the
shares): (i) will have been duly authorized, legally issued, fully paid and
non-assessable, (ii) when issued will be a valid and binding obligation of the
corporation, and (iii) do not require a permit from any governmental agency.

This opinion does not cover any matters related to any re-offer or re-sale of
the Shares by the Plan Beneficiary, once issued pursuant to the Plan as
described in the Registration Statement.

My opinion is subject to the qualification that no opinion is expressed herein
as to the application of the state securities or Blue-Sky laws.
