Breakthrough has been recorded by
Scientist in the designing of an object that will limit the spread of HIV
during sexual intercourse.
Success has been recorded when a
test was carried out on teenage girls in the US and plans are currently ongoing
to carryout test in Africa.
The viginal ring which is said to
prevent HIV infection contains anti-retroviral drug called dapivirine and is
used for a month at a time.
Dapivirine inhibits HIV’s reverse
transcriptase enzyme, a protein vital to HIV’s ability to replicate and cause
an infection.
One or more microbicides are
contained in each intravaginal ring that are intended to be delivered into the
vaginal compartment at a high concentration and to be directly absorbed by the
cells and tissues.
The usage of this flexible
viginal ring which sits on the cervix gives women the freedom to protect
themselves without relying on men to wear condoms. The viginal ring is said to
cut infection by 56%.
The study concluded that the ring
was safe and acceptable to young women, after a six-month trial to ascertain
its effectiveness. The result revealed that 87 percent of ninety-six sexually
active girls who partook had detectable levels of the drug in their vagina.
Principal investigator and vice
chair of the department of obstetrics, gynecology and reproductive sciences at
the University of Pittsburgh School of Medicine Sharon Hillier said “HIV
doesn’t distinguish between a 16-year-old and an 18-year-old. Access to safe
and effective HIV prevention shouldn’t either, young women of all ages deserve
to be protected.”
This would be the first method of
prevention exclusively for women, if the ring gets regulatory approval.
The study was presented at the
9th International AIDS Society conference in Paris.
