Hesitancy of COVID-19 vaccines: Rapid systematic review of the measurement, predictors, and preventive strategies.

Vaccine hesitancy is one of the top ten global health threats and the first threat to fighting COVID-19 through vaccination. With the increasing level of COVID-19 vaccine hesitancy amidst the rising level of confirmed cases and death tolls, this paper provides rapid systematic literature reviews on the measurement of COVID-19 vaccine hesitancy, key determinants and evidence-based strategies to prevent COVID-19 vaccine hesitancy. The findings reveal three standard measures of vaccine hesitancy: optional response questions, Likert scale, and linear scale measurements. Factors such as sociodemographic/economic factors, occupational factors, knowledge on the vaccine, vaccine attributes, conspiracy belief and psychological factors are the major predictors of COVID-19 vaccine hesitancy. Evidence-based findings identified measures such as effective education on the vaccine, clear and consistent communication to build public confidence and trust, health education on vaccination and its social benefit, outreach program and targeted messaging to minimize COVID-19 vaccine hesitancy.

Business response to COVID-19 impact: Effectiveness analysis in South Africa

Background: Following the outbreak of Coronavirus disease 2019 (COVID-19), many businesses have put out measures to counter the impact of the outbreak and its related reactions from economic actors (individuals, authorities and other businesses) on their business operations. However, nearly no empirical studies or reports have been carried out to investigate the effectiveness of those measures. Aim: This study aimed at examining the effectiveness of business response measures to COVID-19 impact on business outcome. Setting: This study focused on businesses that are value-added tax (VAT) registered. Methods: A cross-sectional survey design was used. The authors applied logistic regression technique to analyse the effectiveness of business response measures on business outcome. Results: The authors found evidence that business responses such as virtual connection, innovative e-commerce and increasing working hours are more effective business responses, whilst decreasing work hours, laying off workers temporarily and ordinary e-commerce are less effective measures against the impact of the outbreak. Furthermore, business characteristics such as industry type (e.g. ‘agriculture, hunting, forestry and fishing’ and ‘electricity, gas and water supply’) are more resilient to COVID-19 shock, whilst pure export market and small businesses, secondary and tertiary, are significantly less resilient. Conclusions: Firstly, the study shows that some business responses are more effective in remediating the adverse impact of COVID-19 and therefore recommends policy intervention and industrial actions to promote them. Secondly, it is also recommended that financial bailout and/or Internet infrastructure and domestic support for small and export businesses could make them more resilient to the adverse impact of the outbreak.
