Background COVID-19 vaccination is efficacious at protecting against severe COVID-19 outcomes in the general population. However, vaccine hesitancy (unwillingness for vaccination despite available vaccination services) threatens public health. Individuals taking immunosuppression for psoriasis have been prioritised for COVID-19 vaccination, however there is a paucity of information on vaccine hesitancy in this population, including contributing factors. While global healthcare has been severely disrupted in the pandemic, the impact on access to psoriasis care and whether this may negatively influence vaccine uptake, is underexplored.Objectives To explore organisational and individual factors associated with COVID-19 vaccine hesitancy in individuals with psoriasis.Methods Individuals with psoriasis, identified through global patient organisations and social media, completed a cross-sectional self-reported online survey. The primary outcome was COVID-19 vaccine hesitancy. Logistic regression was used to examine the association between predictor variables (organisational and individual factors) and outcome.Results Self-reported data from 802 individuals with psoriasis across 89 countries were available (65.6% female, median age 51 years [IQR 37-61], 43.7% taking systemic immunosuppression). Eight percent (n=63) reported vaccine hesitancy. Those reporting vaccine hesitancy were younger, more likely to be of non-white ethnicity, non-UK resident, have a lower BMI, not taking systemic immunosuppression and with shorter disease duration compared to those not reporting vaccine hesitancy. The commonest reasons for vaccine hesitancy were concerns regarding vaccine side-effects, that the vaccine is too new or that psoriasis may worsen post-vaccination. Forty percent (n=322) reported that their psoriasis care had been disrupted by the pandemic. These individuals were younger, of non-white ethnicity, with shorter duration and more severe psoriasis. Disruption to psoriasis care was associated with vaccine hesitancy (unadjusted OR 2.97 (95%CI 1.23-7.13), p=0.015), although not statistically significant in the adjusted model.Conclusion A minority of individuals with psoriasis from our study reported COVID-19 vaccine hesitancy. Similar to general population trends, vaccine hesitancy in our psoriasis sample is most common in younger age and ethnic minority groups. Our data highlight patient concerns regarding COVID-19 vaccination, which are important to address during patient-clinician interactions to help optimise vaccine uptake and mitigate risks from the ongoing pandemic in individuals with psoriasis.What’s already known about this topic?The COVID-19 vaccine is highly efficacious at protecting against severe COVID-19 outcomes in the general population. Vaccine hesitancy (unwillingness to receive vaccination despite available vaccination services) poses a major threat to global public health and is more common in women, younger age and ethnic minority groups in the general population.Individuals with psoriasis taking systemic immunosuppression were considered at high risk of severe COVID-19 outcomes and prioritised for vaccination, however there is a paucity of information on vaccine hesitancy in this group, including contributing factors.While global healthcare has been severely disrupted by the COVID-19 pandemic, access to psoriasis care and its potential impact on vaccine hesitancy is underexplored.What does this study add?A substantial proportion (40%) of individuals with psoriasis reported disrupted access to psoriasis care during the COVID-19 pandemic. Disrupted care was most commonly reported in younger age and ethnic minority groups.COVID-19 vaccine hesitancy was reported by a minority (8%) of individuals with psoriasis. Those reporting vaccine hesitancy were younger and more likely to be of non-white ethnicity, in keeping with trends in the general population.The commonest reasons for vaccine hesitancy were concerns regarding vaccine side effects, that the vaccine is too new or that psoriasis may worsen post-vaccination. These concerns are important to address during patient-clinician interactions to help mitigate risks from the ongoing pandemic in individuals with psoriasis.Competing Interest StatementNothing to disclose: Dr Bechman, Ms Cook, Dr Dand, Prof. Langan, Dr. Norton, Dr. Tsakok, Dr. Yiu, Dr De La Cruz, Dr. Contreras, Ms. Vesty, Ms. Vincent, Mr. Bola Coker, Ms. Meynell, Dr. Lambert, Prof. Brown, Prof. Naldi.

Background: timely assessment of the burden of HIV/AIDS is essential for policy setting and programme evaluation. In this report from the Global Burden of Disease Study 2015 (GBD 2015), we provide national estimates of levels and trends of HIV/AIDS incidence, prevalence, coverage of antiretroviral therapy (ART), and mortality for 195 countries and territories from 1980 to 2015.Methods: for countries without high-quality vital registration data, we estimated prevalence and incidence with data from antenatal care clinics and population-based seroprevalence surveys, and with assumptions by age and sex on initial CD4 distribution at infection, CD4 progression rates (probability of progression from higher to lower CD4 cell-count category), on and off antiretroviral therapy (ART) mortality, and mortality from all other causes. Our estimation strategy links the GBD 2015 assessment of all-cause mortality and estimation of incidence and prevalence so that for each draw from the uncertainty distribution all assumptions used in each step are internally consistent. We estimated incidence, prevalence, and death with GBD versions of the Estimation and Projection Package (EPP) and Spectrum software originally developed by the Joint United Nations Programme on HIV/AIDS (UNAIDS). We used an open-source version of EPP and recoded Spectrum for speed, and used updated assumptions from systematic reviews of the literature and GBD demographic data. For countries with high-quality vital registration data, we developed the cohort incidence bias adjustment model to estimate HIV incidence and prevalence largely from the number of deaths caused by HIV recorded in cause-of-death statistics. We corrected these statistics for garbage coding and HIV misclassification.Findings: global HIV incidence reached its peak in 1997, at 3·3 million new infections (95% uncertainty interval [UI] 3·1–3·4 million). Annual incidence has stayed relatively constant at about 2·6 million per year (range 2·5–2·8 million) since 2005, after a period of fast decline between 1997 and 2005. The number of people living with HIV/AIDS has been steadily increasing and reached 38·8 million (95% UI 37·6–40·4 million) in 2015. At the same time, HIV/AIDS mortality has been declining at a steady pace, from a peak of 1·8 million deaths (95% UI 1·7–1·9 million) in 2005, to 1·2 million deaths (1·1–1·3 million) in 2015. We recorded substantial heterogeneity in the levels and trends of HIV/AIDS across countries. Although many countries have experienced decreases in HIV/AIDS mortality and in annual new infections, other countries have had slowdowns or increases in rates of change in annual new infections.Interpretation: scale-up of ART and prevention of mother-to-child transmission has been one of the great successes of global health in the past two decades. However, in the past decade, progress in reducing new infections has been slow, development assistance for health devoted to HIV has stagnated, and resources for health in low-income countries have grown slowly. Achievement of the new ambitious goals for HIV enshrined in Sustainable Development Goal 3 and the 90-90-90 UNAIDS targets will be challenging, and will need continued efforts from governments and international agencies in the next 15 years to end AIDS by 2030.FundingBill & Melinda Gates Foundation, and National Institute of Mental Health and National Institute on Aging, National Institutes of Health
