Objective: This study aims to determine the acceptability of a COVID-19 vaccine among healthcare workers in Saudi Arabia and the factors affecting their intention to accept the vaccine.Methods: The study used data from an online cross-sectional survey that was conducted in Saudi Arabia between 8 December 2020 and 14 December 2020. This study employed bivariate and multivariable regression analyses. The bivariate was used to describe and tabulate the frequency of all the variables, including the sociodemographic characteristics, the risk perception and the acceptance of the COVID-19 vaccination and a chi-squared test of independence was calculated. Multivariable logistic regression models were employed to examine and identify the factors associated with an intention to have the COVID-19 vaccination and the factors associated with its immediate acceptance.Results: Of the total of 736 healthcare workers who began the online questionnaire, 673 completed it (a 91.44% completion rate). Among the study participants, 50.52% were willing to have the COVID-19 vaccine, of which 49.71% intended to have the vaccine as soon as it becomes available in the country, while 50.29% would delay until the vaccine's safety is confirmed. Being a male healthcare worker, perceiving a high risk of infection, and believing that the COVID-19 vaccine should be compulsory for all citizens and residents in the country increased the probability of intention to vaccinate against COVID-19 and the probability of accepting the COVID-19 vaccination as soon as possible.Conclusion: This study calls for more health-related education among healthcare workers to alleviate any fears that might be associated with the COVID-19 vaccine.

The purpose of this study is to review recent developments pertaining to risk management in Islamic banking and finance literature. The study explores the fundamental features of risks associated with Islamic banks (IBs) as compared to those associated with conventional banks (CBs) in order to determine the extent to which IBs engage in effective risk mitigation. The study includes a consideration of the major studies in which the fundamental features of Islamic banks and finance (IBF) and the main characteristics of risk management in IBs are analyzed in comparison with those of CBs. Specifically, these two kinds of banks are compared in relation to the types of risks faced, the characteristics of those risks, and the nature and extent of exposure to those risks. A tabular methodology approach is used in concert with a comparative literature review approach for the analysis. The results show that there is weak support for Shariah-based product development due to the lack of risk mitigation expertise in IBs. The conclusion presented is that in comparison with CBs, IBs are more risk-sensitive due to the nature of their products, contract structure, legal costing, governance practices, and liquidity infrastructure. Furthermore, the determinants of the credit risk of Islamic banks in Malaysia (MIBs) are examined. Overall, bank capital and financing expansion have a significant negative impact on the credit risk level of IBs in Malaysia.

Purpose The purpose of this paper is to compare the return performance and persistence of ethical and conventional mutual funds during two extreme events, the Asian and the global financial crises under Shariah constraints. Design/methodology/approach The overall sample comprises of 129 Islamic mutual funds (IMFs) and 350 conventional mutual funds (CMFs) in Malaysia, and the average monthly data cover two periods of market cycles, before and during a financial crisis. The net of all expenses data is obtained from the Morningstar Database. This study employs various market risk-adjusted performance measures (ratios) to estimate the funds’ overall performance during the crises, and then it uses CAPM model to estimate the parameters via panel data approach. Moreover, paper employs the two persistence performance measures on IMFs and CMFs through contingency tables. It tests for the performance persistence effects for IMFs, CMFs using repeat winner and the cross-product ratio (CPR) tests proposed by Malkiel (1995) and Brown and Goetzmann (1995), respectively. Findings The main findings of the paper are: on average, both funds IMF and the CMF outperform the market return during the entire sample period; none of the funds is better than the “others” during the financial crises and the pre-crisis periods; the ethical fund – IMF outperforms the CMF over the study period. This outcome also indicates that ethical funds are more persistent especially during and the pre-crisis AFC and the GFC periods. Research limitations/implications The finding of this study is limited to only Malaysian data because the objective was to guideline investors and market players in Malaysia to prefer investing in Islamic ethical funds to diversify their investment portfolio. Practical implications Cautions to use existing ratio measures and CAPM model rather persistence measures may be used with existing methodologies in light of extreme events which influenced investor decision making for better returns at lower risks. Social implications A class of ethical funds consists of religious sustainable, socially responsible and impact-investing (SRI) funds but Shariah implications of halal investment must be observed to avoid prohibited practices within the class of SRI funds. Originality/value The work done in this paper are original in the sense that the authors employed various ratios to measure fund performance in conjunction with CAPM model and then tested for two persistence performance measures; the repeat winner and CPR tests.
