for hiv-positive patients could
antiviral medication render them safe as
partners we're going to take the
uninfected person and try and develop
safe and effective ways to prevent the
acquisition of the virus through
pre-exposure prophylaxis pre-exposure
prophylaxis or prep
was not a completely new concept malaria
prophylaxis has been used for years you
basically take a medication it's in your
body and then you get exposed to malaria
and prevents you from actually getting
malaria not a vaccine but a short-term
preventative so this made sense to me to
use an HIV medication to prevent HIV
infection at least that's what they
hoped would healthy people really take
this medicine the skepticism was could
people take a pill every day which was
hard enough to do in the treatment world
it's been harder for people to take
preventative medications despite the
concerns the trials forged ahead the big
prep study was called iprex oh there is
a lot of pressure writing on the study
of iprex everyone in HIV is waiting for
it this was the first time that there
would be a pill where you could prevent
getting HIV
when I saw the results I was elated I
was amazed I was so excited in iprex
prep cut the risk of new infection by
more than 70 percent for people who
stuck to the regimen further studies
show prep cuts the risk of HIV infection
from having sex by 99 percent
and at least 74 percent for people who
inject drugs
prep relies on the same type of drugs as
are used for treatment
taken as a preventative medication
it creates a defensive shield and the
HIV comes into your body but that
medication comes and attacks it and
prevents it from essentially infecting
your cells that still left the tasp
trial
Cohen's Landmark study of treatment as
prevention
can you come over to the NIH so we all
drove over to the NIH
they're in a room with a large group of
people including the leader Dr divenbach
and then after a few minutes of cajole
and he kind of there's a huge stack of
papers and he threw up this stack of
papers in the area and said this is a
home run
treatment as prevention worked
we reported that we stopped the
transmission of HIV by more than 96
percent
an hiv-positive person whose treatment
brings the viral load so low as to be
undetectable will not transmit the virus
me being undetectable or means being
able to live again actually live a
normal life and not be scared
