  • We conducted a meta-analysis to summarize rates of sexually transmitted infections among men who have sex with men (MSM) on pre-exposure prophylaxis (PrEP) for HIV versus MSM not using PrEP. Incidence rate ratios showed that MSM using PrEP were 25.3 times more likely to acquire a Neisseria gonorrhoeae infection, 11.2 times more likely to acquire a Chlamydia trachomatis infection, and 44.6 times more likely to acquire a syphilis infection versus MSM not using PrEP.

  • Our results suggest that racial and ethnic disparities in provider recommendations and HPV vaccinations have waned over time among males and females. While these trends are welcomed, additional interventions are warranted to increase overall rates of vaccination across race, ethnicity, and gender.

  • Despite an average frequency of at most ~1 VRC01-class precursor per mouse, we found that at least 29% of singly-immunized mice produced a VRC01-class memory response, suggesting that priming generally succeeded when at least one precursor was present. The results demonstrate the feasibility of using germline targeting to prime specific and exceedingly rare bnAb precursor B cells within a human-like repertoire.

  • We report the development of boosting immunogens designed to guide the genetic and functional maturation of previously primed VRC01-class precursors. Boosting a transgenic mouse model expressing germline VRC01 heavy chains produced broad neutralization of near-native isolates (N276A) and weak neutralization of fully native HIV.

  • We have developed stabilized native-like trimer immunogens for germline-targeting and boosting of glycan-dependent PGT121-class bnAb responses against HIV. The immunogens and boosting schemes we created are candidates for human vaccine testing and further optimization, and the methods developed here are applicable to immunogen design for other epitopes and pathogens and thus are of relevance for future vaccine design.

  • One thousand street and labour children, aged 10–18 years, were recruited....4.5% were HIV infected, 1.7% with hepatitis B virus and 2.6% with hepatitis C virus. HIV prevalence among street children is much higher than general population and, in fact, the rate of positivity comes close to that among female sex workers in Iran. These findings must be an alarm for HIV policymakers to consider immediate and special interventions.

  • To understand mechanisms of protection by neutralizing antibodies, Liu et al. first treated rhesus macaques with an antibody known to block infection, then infected them with a monkey-adapted HIV-1....Viral DNA and RNA were found in the macaques' gut and lymph nodes a few days after genital tract infection. This suggests that antibodies may block the virus in multiple sites throughout the body, rather than just at the site of entry.

  • A new public-private coalition that aims to derail epidemics by speeding development of vaccines has now hung its shingle with the backing of the Wellcome Trust and Bill & Melinda Gates Foundation. The Coalition for Epidemic Preparedness Innovations (CEPI), which launched its website today, grew out of the widespread conviction that vaccines languishing in R&D could have prevented the recent Ebola epidemic in West Africa that killed more than 11,000 people.

  • Surveys were conducted with 480 women and 480 men obtaining HIV services from 18 clinics 1 year after the sites were randomized to integrated FP/HIV services or standard referral for FP. Men at intervention sites had stronger gender equitable attitudes than those at control sites. Among women, attitudes did not differ by study arm. Gender equitable attitudes were not associated with contraceptive use among men or women. Further work is needed to understand how integrating FP into HIV care affects gender relations, and how improved gender equity among men might be leveraged.

  • The efficacy and safety of ART has substantially improved with the introduction of newer drug classes of antiretrovirals that are now available to patients and HIV care providers. Their improved tolerance could be part of a larger solution to improve retention, which is a challenge, particularly in low-income and middle-income country settings.

  • Taking money from much-needed research and health care to develop a vaccine against one disease itself costs lives. One analysis estimated that redirecting money to Ebola and away from common infections such as malaria and HIV caused nearly as many deaths as Ebola itself....Triaging disease research and funding is always a complex issue, and, too often, public sentiment rather than health need drives policy. But it doesn’t need to be that way.
