Retracted research publications reached an all-time high in 2023, and COVID-19 publications may have higher retraction rates than other publications. To better understand the impact of COVID-19 on the research literature, we analyzed 244 retracted publications related to COVID-19 in the PubMed database and the reasons for their retraction. Peer-review manipulation (18.4%) and error (20.9%) were the most common reasons for retraction, with time to retraction occurring far more quickly than in the past (13.2 mos, compared with 32.9 mos in a 2012 study). Publications focused on controversial topics were retracted rapidly (mean time to retraction 10.8 mos) but continued to receive media attention, suggesting that retraction alone may be insufficient to prevent the spread of scientific misinformation. More than half of the retractions resulted from problems that could have been detected prior to publication, including compromise of the peer review process, plagiarism, authorship issues, lack of ethics approvals, or journal errors, suggesting that more robust screening and peer review by journals can help to mitigate the recent rise in retractions.

The field of global health law has evolved over the past decade to describe new legal and policy instruments that apply to a changing set of public health threats, non-state actors, and regulatory norms that structure the global response to public health challenges. This special issue—bringing together the O’Neill Institute for National & Global Health Law and the Global Health Law Consortium—examines the expansive evolution of the field of global health law and its continuing development to face new health threats.

The COVID-19 pandemic significantly challenged the mental health of children and adolescents, with existing research highlighting the negative effects of restrictive measures to control the virus’s spread. However, in the specific context of this pandemic, there is limited understanding of how these difficulties have persisted over time after the situation was fully restored. This study sought to evaluate the pandemic’s impact on psychological symptoms in children from Italy, Spain, and Portugal across five-time points (2, 5, and 8 weeks, 6 months, and three and a half years after the pandemic’s onset). A total of 1613 parents completed the Psychological Impact of COVID-19 and Confinement on Children and Adolescents Scale, reporting symptoms in their children aged 3–17 years (39.2% female). The findings reveal an initial surge in psychological difficulties—anxiety, mood, sleep, behavioral, eating, and cognitive disturbances—followed by improvements in these domains three and a half years later. By September 2023, Spanish children experienced more significant reductions in symptoms compared to their Italian and Portuguese peers. While the COVID-19 pandemic has been a prolonged crisis, with varying impacts over time and across regions depending on the strictness of restrictions, the trends suggest a gradual improvement in the psychological well-being of children and adolescents.

Despite internet use potentially reducing loneliness among older adults during the Covid-19 pandemic, quantitative research in this area is limited. Our study addresses this gap by exploring how internet use affects loneliness worsening in old age across Europe from a gendered perspective. We adopt a comprehensive approach, considering individual and contextual factors. Using multi-level modelling, we analyse data from the Survey of Health, Ageing and Retirement in Europe (Wave 8 and Corona Survey 1), supplemented by the Oxford Covid-19 Government Response Tracker and the Eurostat Digital Agenda Scoreboard Key Indicators. The empirical analysis has revealed gender-specific differences in the relationship between internet use and the worsening of loneliness among older people during the pandemic, with internet use contributing to increased loneliness for older women, but not for men. In addition, our study indicates that while the contextual factors, namely the severity of the contingency measures and the quality of the internet connection, are not moderators of the relationship between internet use and loneliness worsening, the stringency index specifically exacerbates loneliness in women. These findings contribute to the development of more effective and targeted interventions to combat loneliness worsening and promote wellbeing among older women, particularly in the context of global health crises such as the Covid-19 pandemic.

Southern European welfare states have historically been characterised by the absence of national safety nets. However, these countries have witnessed a succession of policy reforms over the past three decades. In 2020, the Spanish Parliament unanimously approved the ‘Ingreso Mínimo Vital’ to finally cease being the only European country without a minimum income scheme at the national level. This article investigates the political and institutional mechanisms that enabled this policy reform, which was particularly unexpected due to the fragmentation of the party system along both ideological and territorial dimensions. To solve this puzzle, I employ the ‘explaining-outcome’ process tracing method and rely on qualitative data from official documents, party manifestos and parliamentary interventions spanning from 2015 to 2020. In addition, I build on ten expert interviews with relevant actors directly involved in the reform, conducted between 2022 and 2024. Findings illustrate that inclusive path departure was possible through two political stages. First, left-wing party competition and strong socio-political demand (2014–2020) allowed for the introduction of the scheme into the political agenda. Second, territorial politics and the external shock of the coronavirus disease 2019 (COVID-19) pandemic ultimately contributed to mitigating expected political cleavages during the parliamentary process.

Health-related quality of life (HRQoL) in the context of COVID-19 is not fully understood. We assessed HRQoL using Patient-Reported Outcomes Measurement Information System® measures among 559 former COVID-19 patients and 298 non-infected individuals. HRQoL was captured once up to 2 years after the initial test. Additionally, we described associations of characteristics with impaired HRQoL. Overall, HRQoL scores were inferior among former patients. A meaningful group difference of at least three T-score points was discernible until 12 months after testing for fatigue (3.1), sleep disturbance (3.5), and dyspnoea (3.7). Cognitive function demonstrated such difference even at >18 months post-infection (3.3). Following dichotomization, pronounced differences in impaired HRQoL were observed in physical (19.2% of former patients, 7.3% of non-infected) and cognitive function (37.6% of former patients, 16.5% of non-infected). Domains most commonly affected among former patients were depression (34.9%), fatigue (37.4%), and cognitive function. Factors that associated with HRQoL impairments among former patients included age (OR ≤2.1), lower education (OR ≤5.3), and COVID-19-related hospitalization (OR ≤4.7), among others. These data underline the need for continued attention of the scientific community to further investigate potential long-term health limitations after COVID-19 to ultimately establish adequate screening and management options for those affected.

The COVID-19 pandemic showed the vital role of Emergency Medical Teams (EMTs) in international surge responses. The EMTs with their internationally skilled team members were able to meaningfully support countries facing the pandemic, especially those who were suffering from scarcity in the quality and quantity of workforce and financial resources within their health systems. This report summarizes the main operational challenges faced by UK-Med and The Polish Center for International Aid (PCPM) Emergency Medical Teams, based on experiences from their 32 COVID-19 deployments. In particular, the paper discusses the hindrances related to Ministries of Health expectations and the changing roles of EMTs during deployments.

This article critically examines the inequities in the access to COVID-19 vaccine and the lessons for global health law. Despite the rapid development and approval of COVID-19 vaccines, the rollout exposed severe systemic failures rooted in preexisting economic distortions and market inefficiencies. The article argues that addressing vaccine inequity requires more than improved distribution and solidarity, but effective reinvention of the global vaccine supply chain through evidence-based and meaningful market-shaping measures. It calls for a transformative approach to global health governance, emphasising the need for a comprehensive, human rights-compliant policy framework to correct structural problems in international markets, moving beyond superficial exhortations to equity.

During outbreaks of diseases like cholera, HIV/AIDS, H1N1, and Ebola, governments often impose international border restrictions (for example, quarantines, entry restrictions, and import restrictions) that disrupt the economy without stopping the spread of disease. During COVID-19, international travel restrictions were ubiquitous despite initial World Health Organization recommendations against such measures because of their limited public health benefit and the potential for imposing a range of harms. Why did governments adopt these measures? This article argues and finds evidence that governments use international border restrictions as security theatre: ‘measures that provide not security, but a sense of it’. Quantitative analysis of original data on states’ first border restrictions during the pandemic suggests that behaviour was not just driven by the risk of COVID-19 spread. Instead, nationalist governments, which are likely to be attracted to policies associating disease with foreigners, were more likely to impose border restrictions, did so more quickly, and adopted domestic measures more slowly. A case study of the US further illustrates the security theatre logic. The findings imply that overcoming or redirecting governments’ attraction to security theatre could promote international cooperation during global health emergencies.
