Men and patriarchy constantly police women’s bodies often to the detriment of women’s health. African women are particularly vulnerable to contracting HIV because they are not in positions of power to negotiate the use of condoms while dating, and more so within marriages and as sex workers. This is reflected in the disproportionate rate of HIV infection amongst African women. Excuses that discourage condom use are male-centric, and include decreased pleasure, discomfort, and a perception that women who encourage condoms within marriage are unfaithful or are demonstrating a lack of trust towards their husbands.
Consequently, there is a focus by healthcare professionals on identifying alternative HIV preventative measures. Previous studies tried using the anti-retroviral tenofivir as a pre-exposure prophylaxis in pills and vaginal gels. Unfortunately, there was little commitment to consistent use, which is critical for preventative success. It is for this reason that the development of an anti-HIV vaginal ring should be met with excitement.
The anti-HIV vaginal ring is a flexible silicone ring, which contains the anti-retroviral dapivirine (Figure 1). Two clinical trials have shown that the ring reduces a woman’s chance of contracting HIV by approximately a third in women below 21; half in women between 21 and 25; and two-thirds in women above 25. The ring was prescribed for a month at a time during the trial, but the younger women were found to remove it during the course of the month. The increased protection amongst older women is due to their more responsible and consistent use.
The ring is easy to insert and it is discreet, which is important for the safety of women who may choose to use it without the knowledge of their partners. At an estimated cost of $5, it has a shelf life of five years and does not require refrigeration which is advantagous in rural settings. Should the ring obtain regulatory approval, it is expected to be available from 2018.
