AIDS: lessons learnt and myths dispelled

This article explores the experiences of sex workers living and working in South Australia under laws that criminalise their profession. A qualitative research methodology was used to interview sex workers about their work experiences. It was found that working in a criminalised setting raised particular concerns for sex workers including an erosion of workplace protections, outreach services, access to health service and increased policing. This article argues that criminalising sex work leads to human rights violations, therefore sex work should be decriminalised to ensure workers are protected. The themes from the interviews build qualitative evidence supporting the decriminalisation of sex work. This research has been supported by the Sex Industry Network of South Australia (SIN).

Synthetic vaccines, in particular long synthetic peptides of approximately 25–50 amino acids in length, are attractive for HIV vaccine development and for induction of therapeutic immune responses in patients with (pre-)malignant disorders. In the case of preventive vaccine development against HIV, no major success has been achieved, but the possibilities are by no means exhausted. A long peptide vaccine consisting of 13 overlapping peptides, which together cover the entire length of the two oncogenic proteins E6 and E7 of high-risk human papilloma virus type 16 (HPV16), caused complete regression of all lesions and eradication of virus in 9 out of 20 women with high-grade vulvar intraepithelial neoplasia, a therapy-resistant preneoplastic disorder. The nature and strength of the vaccine-prompted T cell responses were significantly correlated with the clinical response. Synthetic peptide vaccines are attractive, because they allow rational improvement of vaccine design and detailed pharmacokinetic and pharmacodynamic studies not possible with conventional vaccines. Improvements are possible by addition or conjugation of adjuvants, notably TLR ligands, to the synthetic peptides.

In recent times there has been a sense that HIV/AIDS control has been attracting a significantly larger portion of donor health funding to the extent that it crowds out funding for other health concerns. Although there is no doubt that HIV/AIDS has absorbed a large share of development assistance for health (DAH), whether HIV/AIDS is actually diverting funding away from other health concerns has yet to be analyzed fully. To fill this vacuum, this study aims to test if a higher level of HIV/AIDS funding is related to a displacement in funding for other health concerns, and if yes, to quantify the magnitude of the displacement effect. Specifically, we consider whether HIV/AIDS DAH has displaced i) TB, ii) malaria iii) health sector and ‘other’ DAH in terms of the dollar amount received for aid. We consider this question within a regression framework controlling for time and recipient heterogeneity. We find displacement effects for malaria and health sector funding but not TB. In particular, the displacement effect for malaria is large and worrying.
