Abstract
Decline in new HIV infections in the Asia-Pacific region (APAC) continues to be slow, emphasising the importance of scaling up new HIV prevention strategies, such as pre-exposure prophylaxis (PrEP). To help inform PrEP rollout in APAC, we conducted a rapid review of published literature on PubMed from 2015 to 2020, to assess feasibility, implementation strategies, cost-effectiveness, and availability of national policies and guidelines; for the latter, we also did an expanded Internet search. This review focussed on nine countries contributing >95% of new infections in this region. A total of 36 PrEP-related studies conducted among men who have sex with men, female sex workers, and transgender women were included, of which 29 were quantitative, six were qualitative and one was a mixed-method study. Most of the studies have addressed the availability and acceptability of PrEP, whereas cost-effectiveness of any approach was assessed by limited studies. Limited published information was available about national PrEP policies and guidelines; of the selected nine countries, five have adopted the recommended World Health Organization PrEP policy of which four have integrated it in their national HIV response. HIV risk perception concerns about safety, side-effects, stigma, and affordability were major challenges to PrEP acceptance. Community-based implementation has the potential to address these. Limited evidence suggested merging PrEP implementation with ongoing targeted intervention and treatment programs could be a cost-effective approach. To stem the epidemic, newer effective prevention strategies, like PrEP, should be urgently adopted within the context of combination HIV prevention approaches.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
