HIV vaccine reported to be successful in trials by Canadian university
Researchers
at the University of Western Ontario recently completed Phase 1 human
trials of a new preventative HIV vaccine, and the results give hope that
they may be on track towards a commercially available vaccine that will
protect against HIV.
The vaccine, called SAV001-H, was developed
by Dr. Chil-Yong Kang and his team at Western University's Schulich
School of Medicine & Dentistry. So far, SAV001-H is unique in being
the only preventative vaccine to use a genetically-modified version of
the whole virus (similar to vaccines for polio, influenza and rabies, to
name a few).
"We infect the cells with a genetically modified
HIV-1," Kang said in an interview with Ontario Business Report. "The
infected cells produce lots of virus, which we collect, purify and
inactivate so that the vaccine won’t cause AIDS in recipients, but will
trigger immune responses."
This will hopefully make the vaccine not only effective, but easy and cheap to produce.
Now,
Phase 1 trials (which started in March of 2012) are specifically to
test if the vaccine is safe, and to identify any side effects (if any).
It's not until Phases 2 and 3 that the actual effectiveness of the
vaccine is truly put to the test. However, it seems that SAV001-H passed
its Phase 1 trials with flying colours, since no adverse effects were
reported in any of the patients that participated in the study.

With
this success, it now opens the doors for Kang and his team to continue
on with Phase 2 trials, where they'll test the vaccine's ability to
produce an immune response and its overall effectiveness.
