MELBOURNE,
Australia--The possibility of an AIDS vaccine
being developed within the next ten years
was a significant topic at the Sunday session
of the Sixth International Congress on
Aids in Asia and the Pacific (ICAAP).
The
main focus of the day was prevention of HIV/AIDS
and increasing awareness about the pandemic.
While countries in the region have already
implemented awareness programs, cultural and
social taboos have prevented widespread dissemination
of information. The development of a vaccine
for HIV is an important component of the push
for HIV prevention, but has remained elusive.
"There has never been more optimism than
there is now that an HIV vaccine can be identified," said
Peggy Johnston, Assistant Director for HIV/AIDS
Vaccines at the National Institutes of Health
(NIH) in the United States.
"However
we don't know what it will look like just
yet, we don't know how it will act,
clinical trials will take a long time and it's
likely that the first ones found to be effective
won't be a 100 percent effective and more development
will be necessary."
Vaccine research is taking place at a number
of pharmaceutical companies and encouraging
results have been found in certain monkey-models
where animals have simian immunodeficiency
virus (SIV), a disease similar to HIV-2.
"Results from animal testing provides
optimism that the vaccine could work in human
situations," said Johnston. But she cautioned
that a vaccine cannot be seen as a substitute
for preventative action like education.
"Since the first vaccines to become available
are unlikely to be completely effective it
will be absolutely essential to deliver it
along with education and promotion of risk
reduction behavior," she said.
An academic led consortium in Australia is
receiving 27 million Australian dollars from
NIH to undertake vaccine research. Community
involvement in this project is seen as imperative
to find a feasible and achievable vaccine.
The Australian Federation of AIDS Organizations,
representing communities most at risk of HIV,
is part of the consortium.
"We know that behavioral prevention works
and in vaccine trials we want to make sure
the practices aren't lost," said Robin
Gorna, Executive Director of AFAO. "We're
advocating best practice behavioral prevention
along with vaccines."
Prevention is the best case scenario--when
people have access to accurate information
as well as the means to protect themselves.
But women and adolescents, two groups most
at risk of infection, remain malinformed about
the virus in many countries.
"The women most likely to contract HIV
are young, poor, marry early and have little
access to accurate information," said
Susan Paxton from the Key Center for Women's
Health.
Education and awareness campaigns have to
be structured to target these groups of people.
"Not enough women know about condoms," said
Princess Rattana-Devi Norodom of Cambodia. "Even
if they do they are faced with stigma if they
use them because condoms are associated with
sex-workers and promiscuous women."
Social and cultural inhibitions toward sex
education in schools and in the community is
a major barrier to empowering women and adolescents,
especially in poor areas.
"Effective HIV/AIDS responses require
respect and reduction of stigma," said
Mrs. Mahatir, First Lady of Malaysia. "We
acknowledge that poverty exacerbates the situation
and we stress the importance of gender equality."
According to UNAIDS Executive Director Peter
Piot, the support of first ladies and political
leaders helps destigmatize issues surrounding
sex and sexual education. But there is still
not enough of a sense of urgency. If governments
wait till people get sick and start dying,
the problem may become insurmountable.
