I've just begun the process of volunteering for a
GP160 vaccine trial.  Before I went for my first 
visit I spoke to a friend who's part of the NIH
trials using the same vaccine;  he mentioned that one
drawback associated with receiving the vaccine was that
there was the possibility that you might not be able 
to be vaccinated at some point in the future, if, for 
example, a different effective vaccine were found.

Today was my first visit, and I asked the doctor about 
this.  He said that while it was likely that I would 
be excluded from subsequent *clinical trials* for vaccines, 
he knew of no medical reason why I wouldn't be able to 
be vaccinated in the future.   

The study's consent form, on the other hand, contains the 
following sentence:

   Receiving this test vaccine might impair your ability to 
   receive other potential AIDS vaccines which may be 
   available now or in the future.  

which seems to indicate a probelm more than just being unable 
to enroll in subsequent trials.  

The doctor continued to maintain that it was just a question 
of enrolling in trials, but I checked with my friend afterwards,
and he was quite sure that there was actually some possible 
medical complication (though he wasn't sure what).

I was wondering if anybody had information on this question.

Thanks much,

Steve
