Stakeholder Perspectives on Workplace Health Promotion: A Qualitative Study of Midsized Employers in Low-Wage Industries
Purpose. Study goals were to (1) describe stakeholder perceptions of workplace health promotion (WHP) appropriateness, (2) describe barriers and facilitators to implementing WHP, (3) learn the extent to which WHP programs are offered to workers' spouses and partners and assess attitudes toward including partners in WHP programs, and (4) describe willingness to collaborate with nonprofit agencies to offer WHP. Design. Five 1.5-hour focus groups. Setting. The focus groups were conducted with representatives of midsized (100–999 workers) workplaces in the Seattle metropolitan area, Washington state. Subjects. Thirty-four human resources professionals in charge of WHP programs and policies from five low-wage industries: accommodation/food services, manufacturing, health care/social assistance, education, and retail trade. Measures. A semistructured discussion guide. Analysis. Qualitative analysis of focus group transcripts using grounded theory to identify themes. Results. Most participants viewed WHP as appropriate, but many expressed reservations about intruding in workers' personal lives. Barriers to implementing WHP included cost, time, logistical challenges, and unsupportive culture. Participants saw value in extending WHP programs to workers' partners, but were unsure how to do so. Most were willing to work with nonprofit agencies to offer WHP. Conclusion. Midsized, low-wage employers face significant barriers to implementing WHP; to reach these employers and their workers, nonprofit agencies and WHP vendors need to offer WHP programs that are inexpensive, turnkey, and easy to adapt. </jats:sec
Workplace Health Promotion Implementation, Readiness, and Capacity Among Midsize Employers in Low-Wage Industries
OBJECTIVE: To describe workplace health promotion (WHP) implementation, readiness, and capacity among mid-sized employers in low-wage industries in the United States. METHODS: A cross-sectional survey of a national sample of mid-sized employers (100–4,999 employees) representing five low-wage industries. RESULTS: Employers’ WHP implementation for both employees and employees’ spouses and partners was low. Readiness scales showed that employers believe WHP would benefit their employees and their companies, but they were less likely to believe that WHP was feasible for their companies. Employers’ capacity to implement WHP was very low; nearly half the sample reported no capacity. CONCLUSION: Mid-sized employers in low-wage industries implement few WHP programs; their responses to readiness and capacity measures indicate that low capacity may be one of the principal barriers to WHP implementation
A New Model for Catalyzing Translational Science: The Early Stage Investigator Mentored Research Scholar Program in HIV Vaccines
Engagement of early stage investigators (ESIs) in the search for a safe and effective vaccine is critical to the success of this highly challenging endeavor. In the wake of disappointing results from a large‐scale efficacy trial, the HIV Vaccine Trials Network (HVTN) and Center for HIV/AIDS Vaccine Immunology (CHAVI) developed a novel mentored research program focused on the translation of findings from nonhuman primate studies to human trials of experimental vaccines. From 2008 to 2011, 14 ESI Scholars were selected from 42 complete applications. Post program surveys and tracked outcomes suggest that the combination of flexible funding, transdisciplinary mentorship, and structured training and networking promoted the scientific contributions and career development of promising ESIs. Embedding a multicomponent research program within collaborative clinical trial networks and research consortia is a promising strategy to attract and retain early career investigators and catalyze important translational science

High Asymptomatic Carriage With the Omicron Variant in South Africa
We report a 23% asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) Omicron carriage rate in participants being enrolled into a clinical trial in South Africa, 15-fold higher than in trials before Omicron. We also found lower CD4 + T-cell counts in persons with human immunodeficiency virus (HIV) strongly correlated with increased odds of being SARS-CoV-2 polymerase chain reaction (PCR) positive

Immune correlates analysis of the Imbokodo (HVTN 705/HPX2008) efficacy trial of a mosaic HIV-1 vaccine regimen evaluated in Southern African people assigned female sex at birth: a two-phase case-control studyResearch in context
Summary: Background: The HVTN 705 Imbokodo trial of 2636 people without HIV and assigned female sex at birth, conducted in southern Africa, evaluated a heterologous HIV-1 vaccine regimen: mosaic adenovirus 26-based vaccine (Ad26.Mos4.HIV) at Months 0, 3, 6, 12 and alum-adjuvanted clade C gp140 at Months 6, 12. Per-protocol vaccine efficacy (VE) against HIV-1 diagnosis from seven to 24 months was 14.1% (95% CI: −22.0% to 39.5%). Immune correlates analysis was performed for markers selected based on prior evidence in efficacy trials and/or nonhuman primate models. Methods: Humoral and cellular immune response markers at Month 7 were evaluated as immune correlates of risk and of protection in a breakthrough case–control cohort (n = 52 cases, 246 non-cases). Primary markers were IgG binding to vaccine-strain gp140, IgG3 binding to diverse Env antigens (IgG3 Env breadth), IgG3 binding to diverse V1V2 antigens (IgG3 V1V2 breadth), antibody-dependent phagocytosis against the vaccine-strain gp140, Env-specific CD4+ and CD8+ T-cell responses, and multi-epitope functions. Findings: No immune markers were statistically significant correlates of risk. IgG3 V1V2 breadth trended toward an inverse association: hazard ratio 0.70 (95% CI: 0.36 to 1.35; p = 0.29) per 10-fold increase and 0.51 (95% CI: 0.21 to 1.24; p = 0.14) in a Cox model with all primary markers. The VE estimate was 11.8% (95% CI: −17.9% to 34.0%) at all IgG3 V1V2 breadth values below 667 weighted geometric mean net MFI; just above this value, the VE estimate sharply increased to 62.6% (95% CI: −17.9% to 89.6%), and further increased to 80.9% (95% CI: −17.9% to 99.5%) at 1471 MFI, the 95th percentile of the marker distribution. Mediation analysis yielded a VE of 35.7% (95% CI: 15.0% to 51.3%) attributable to the vaccine's impact on this marker. Interpretation: The trend in association of greater IgG3 V1V2 antibody breadth with lower likelihood of HIV acquisition is consistent with the identification of antibodies against V1V2 as immune correlates in three other HIV vaccine efficacy trials and suggests that a greater emphasis should be placed on studying this region in the HIV-1 envelope as a vaccine immunogen.

Hybrid versus vaccine immunity of mRNA-1273 among people living with HIV in East and Southern Africa: a prospective cohort analysis from the multicentre CoVPN 3008 (Ubuntu) studyResearch in context
Summary: Background: With limited access to mRNA COVID-19 vaccines in lower income countries, and people living with HIV (PLWH) largely excluded from clinical trials, Part A of the multicentre CoVPN 3008 (Ubuntu) study aimed to assess the safety of mRNA-1273, the relative effectiveness of hybrid versus vaccine immunity, and SARS-CoV-2 viral persistence among PLWH in East and Southern Africa during the omicron outbreak. Methods: Previously unvaccinated adults with HIV and/or other comorbidities associated with severe COVID-19 received either one (hybrid immunity) or two (vaccine immunity) 100-mcg doses of ancestral strain mRNA-1273 in the first month, depending on baseline evidence of prior SARS-CoV-2 infection. In a prospective cohort study design, we used covariate-adjusted Cox regression and counterfactual cumulative incidence methods to determine the hazard ratio and relative risk of COVID-19 and severe COVID-19 with hybrid versus vaccine immunity within six months. The ongoing Ubuntu study is registered on ClinicalTrials.gov (NCT05168813) and this work was conducted from December 2021 to March 2023. Findings: Between December 2021 and September 2022, 14,237 participants enrolled, and 14,002 (83% PLWH, 69% SARS-CoV-2 seropositive) were included in the analyses. Vaccinations were safe and well tolerated. Common adverse events were pain or tenderness at the injection site (26.7%), headache (20.4%), and malaise (20.3%). Severe adverse events were rare (0.8% of participants after the first and 1.1% after the second vaccination), and none were life-threatening or fatal. Among PLWH, the median CD4 count was 635 cells/μl and 18.5% had HIV viraemia. The six-month cumulative incidences in the hybrid immunity and vaccine immunity groups were 2.02% (95% confidence interval [CI] 1.61–2.44) and 3.40% (95% CI 2.30–4.49) for COVID-19, and 0.048% (95% CI 0.00–0.10) and 0.32% (95% CI 0.59–0.63) for severe COVID-19. Among all PLWH the hybrid immunity group had a 42% lower hazard rate of COVID-19 (hazard ratio [HR] 0.58; 95% CI 0.44–0.77; p < 0.001) and a 73% lower hazard rate of severe COVID-19 (HR 0.27; 95% CI 0.07–1.04; p = 0.056) than the vaccine immunity group, but this effect was not seen among PLWH with CD4 counts <350 cells/μl or HIV viraemia. Twenty PLWH had persistent SARS-CoV-2 virus at least 50 days. Interpretation: Hybrid immunity was associated with superior protection from COVID-19 compared to vaccine immunity with the ancestral mRNA-1273 vaccine. Persistent infections among immunocompromised PLWH may provide reservoirs for emerging variants. Funding: National Institute of Allergy and Infectious Diseases
