Social media played an irreplaceable role in young people’s online social life and information consumption during the COVID-19 pandemic. This research focuses on the impact of excessive information on social media about COVID-19 vaccines on Generation Z's (Gen Z) associated psychological states and long-term vaccine advocacy.

The research conducted structural equation modeling analysis with online survey data from 409 Gen Z citizens in the UK.

The findings suggest that excessive information increased Gen Z social media users' ambivalence and conspiracy beliefs around COVID-19 vaccines, which, in turn, reduced their long-term vaccine advocacy in terms of vaccine acceptance, vaccination intention and vaccine promotion. Importantly, Gen Z’s confidence in government and in the healthcare systems during COVID-19 was effective in helping them overcome the detrimental effects of conspiracy beliefs and ambivalence about long-term vaccine advocacy, respectively.

This research reveals the “dark side” of social media use in the post-pandemic period and highlights the significant roles played by social institutions in mitigating the detrimental effects of Gen Z’s support in social decisions. Beyond the context of COVID-19, this research has important implications for facilitating the civic engagement of Gen Z and boosting their confidence in social institutions in terms of social cohesion.

The SARS-Cov2 pandemic has generated considerable debate about the role of vaccines in the fight against epidemics and the sensitivity and acceptability of new vaccines in emergency situations. The aim of this paper is to examine the nature of the relationship between remittances as an additional source of income and the acceptance of the COVID-19 vaccine and to provide an overview of the determinants of acceptance or hesitancy of the COVID-19 vaccine. It uses logistic regression and propensity score matching to study the relationship between remittances and COVID-19 vaccine acceptance. Using data from the Arab Barometer survey (2021–2022) for 10 Middle East and North Africa (MENA) countries, the results indicate that the number of people vaccinated among remittance recipients is higher than among those who do not receive remittances. The impact of international migration on vaccine acceptance in countries of origin can be seen in the transfer of norms and beliefs from host countries.

The paper uses logistic regression and propensity score matching to study the relationship between remittances and COVID-19 vaccine acceptance. using data from the Arab Barometer survey (2021–2022) for 10 MENA countries.

The results indicate that the number of people vaccinated among remittance recipients is higher than among those who do not receive remittances. The impact of international migration on vaccine acceptance in countries of origin can be seen in the transfer of norms and beliefs from host countries.

Other variables possibly linked to vaccine acceptance can be incorporated into the study.

In countries of origin, international migration should be taken into account in health policies. The convergence of health standards between developed and developing countries can also be achieved through international migration.

The link between migration, through remittances as a proxy for norm transfers, and health, particularly vaccine acceptance in a period of health crisis, has never been addressed in the literature.

Many countries have a significant vaccination hesitancy rate regardless of vaccine prosperity. This study aims to identify factors restricting hesitancy and fostering vaccination intention and uptake against coronavirus in Vietnam.

The study has proposed an extended COM-B model based on the Theoretical Domains Framework to explore critical factors influencing vaccination intention and uptake in Vietnam. A database was collected from 1,015 suitable respondents who had received at least one dose of the COVID-19 vaccine, and ten hypotheses were tested by the partial least squares structural equation model.

The findings showed that six factors, including knowledge, experience, resource, social influence, belief and reinforcement, have either direct or indirect positive effects on COVID-19 vaccine uptake behavior. The output also indicated that personal experience positively affects vaccination intention and uptake.

This study contributes to understanding COVID-19 vaccine uptake behavior by identifying several direct and indirect factors of the extended COM-B model that include “knowledge” and “reinforcement” in shaping behavior change. The study adds to the literature on COVID-19 vaccine uptake behavior and could help achieve higher vaccination rates, ultimately leading to better control of the pandemic.

Several countries, such as South Africa and India, believe that intellectual property rights (IPRs), including patents, impede the efficient increase in vaccine production to inoculate the global population as they scramble to recover from the COVID-19 pandemic. Their proposal at the World Trade Organization (WTO) to waive these pharmaceutical patents has been met with resistance from a few developed countries, who believe that the abrogation of IPRs is unnecessary, even during a pandemic. The purpose of this paper is to discuss the impact of a potential waiver of medical patents at the WTO versus the status quo of IPR laws in the global economy.

This study examines key arguments from economic and moral standpoints regarding the provisions of the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement and other related international agreements and their validity based on the premise of the internalisation of positive externalities posed by vaccines.

The effectiveness of the TRIPS agreement in securing medical access is weak on account of the ability of profit-making multinationals to secure IP rights and on account of the Trans-Pacific Partnership, a multilateral agreement that supports patent evergreening and a period of protection on test data which challenges the access to medicines and the fundamental human right to health.

This study examines international IPRs through the lens of human rights and proposes a new system that balances the two.

This study investigate urban migrant dwellers’ gender and age differences in response to the specific phobia of COVID-19 and hesitancy toward vaccines in the slum settlements.

The study anchored on the two-factor model proposed by Mowrer (1939) and used a quantitative design approach with a convenience sampling method for data gathering among 362 urban migrants residing and working in the cities of Ghana. The study used the Mann–Whitney U test and the regression analysis for the analysis.

The result showed that there is a significant difference between males and females in their understanding of economic phobia, thoughts on social phobia and perception level of vaccine hesitancy. Additionally, there is a significant difference between age groups in their level of thoughts of psychological phobia, economic phobia and thoughts of vaccine hesitancy. Finally, the specific of phobias of COVID-19 are significant predictors of vaccine hesitancy.

This research is slum-specific, which implies that the outcome cannot be generalized to other geographical settings.

The study demonstrates how a pandemic manifests itself to dwellers in slums. The outcome of the study sheds light on how policymakers appreciate the dynamics of the pandemic in a developing country, which may guide future responses to pandemics.

The purpose of this paper is to critically assess the function of the media during the COVID-19 pandemic. It tries to understand how media corporations selectively polish a certain narrative against the other. It will also take into consideration the role of fact-checking agencies and its reliability in determining what is right and wrong.

This study uses qualitative methods and relies on secondary data available in academic domains. In this paper, a specific case related with the COVID-19 pandemic is taken up. Conflicting accounts of health professionals both in academic and industry are compared and analysed. Professional integrity of fact-checking agencies as well goes through scrutiny.

After conducting a critical analysis, it is observed that media houses have violated certain ethics while presenting news and opinions during the COVID-19 pandemic. Without any consideration of fair presentation, the mainstream media resorted to presenting vaccine hesitancy as conspiracy and deplatformed such voice from the media. This violates one’s freedom to free speech and expression.

It is a viewpoint from the side of a free speech abolitionist.

Press will realize that it failed in a number of occasions to uphold and protect its ethical values.

A study questioning the role of media during the COVID-9 pandemic is rare. In this regard, adequate literature is always a difficulty considering the amount of censorship imposed by health agencies, academic institutions and the media. This particular study is built of limited yet reliable information made available by academicians and independent health professionals. As such, the value of work which focuses on the alternative perspectives is believed to add value to health professionals, policymakers, media professionals and the general population.

The present study empirically examines the impact of coronavirus disease 2019 (COVID-19) and policy uncertainty on stock prices in India during the COVID-19 pandemic.

To this end, the authors use the daily data by applying the autoregressive distributed lag (ARDL) model, which tests the short- and long-run relationship between stock price and its covariates.

The study finds that increased uncertainty has adverse short- and long-run effects on stock prices, while the vaccine index has favorable effects on stock market recovery.

From investors' perspectives, volatility in the Indian stock market has negative repercussions. Therefore, to protect investors' sentiments, policymakers should be concerned about the uncertainty induced by the COVID-19 pandemic and similar other uncertainty prevailing in the financial markets.

This study used the news-based COVID-19 index and vaccine index to measure recent pandemic-induced uncertainty. The result carries some policy implications for an emerging economy like India.

Crises, such as COVID-19 pandemic, are critical events that provoke important changes in organizational practices, regulations and actors' roles. The pharmaceutical sector has been strongly affected because of the urgency to produce drugs that are effective and safe. However, the validation process and regulations are historically restrictive in this sector. This study aims to study how biotechnology firms, small companies lacking resources, have undertaken strategic actions during crisis time to induce important changes to their advantage within such a highly regulated environment.

Interviews were conducted with 21 managers in four mRNA-based biotechnology firms.

Results showed that rhetorical strategies and institutional actions are used in order to manage change opportunities. Media attention, greater openness of state agencies and public willingness to accept new ways of treatment illustrated this opportunity of change in favor of biotechnology firms.

Highly regulated environments tend to be unfavorable to smaller firms with limited resources to overcome these constraints. The authors show that times of crisis can reverse this assumption through the provision of new opportunities as long as the smaller firms skillfully use strategic actions to exploit the institutional changes at play.

This paper aims to examine the impact of announcements related to 77 interventions by 46 listed Indian pharmaceutical firms during COVID-19 on the abnormal returns of the firms. The study also finds the variables which explain cumulative abnormal returns (CARs).

This study uses standard event methodology to compute the abnormal returns of firms announcing pharmaceutical interventions in 2020 and 2021. Besides this, the multilayer perceptron technique is applied to identify the variables that influence the CARs of the sample firms.

The results show the presence of abnormal returns of 0.64% one day before the announcement, indicating information leakage. The multilayer perceptron approach identifies five variables that explain the CARs of the sample companies, which are licensing_age, licensing_size, size, commercialization_age and approval_age.

The study contributes to the efficient market literature by revealing how firm-specific nonfinancial disclosures affect stock prices, especially in times of crisis like pandemics. Prior research focused on determining the effect of COVID-19 variables on abnormal returns. This is the first research to use artificial neural networks to determine which firm-specific variables and pharmaceutical interventions can influence CARs.

The purpose of this study focused on a global longitudinal bibliometric mapping of research in the field of health biotechnology between 1990 and 2023 to determine who is leading this field of knowledge and to estimate the sub-disciplines that are emerging and project those that will prevail in the future.

The study identified the most relevant countries, institutions and researchers, as well as the type of scientific collaborations. The applied steps applied in the study were the following: identification and selection of keyword terms by a panel of experts; design and application of an algorithm to identify these selected keywords in titles, abstracts and keywords using Web of Science terms to contrast them; performance of JCR data processing during 2023 using R, Python and VOSviewer.

Among the most relevant conclusions of the study are the following exponential growth has been observed in the study period; new branches of knowledge have emerged in which the subjects have been acquiring their own autonomous capabilities; and R&D in this field is still concentrated in a small group of core countries, and the trend is for it to remain so due to the capacity needs required.

This contribution seeks to systematize the existing scientific knowledge in the field of biotechnology, specifically in the area of health, using the technique of scientific mapping based on a logical model of indicators that aims to determine potential thematic ramifications.
