Summary: In this study, a novel mathematical model is developed to address the equitable allocation of COVID-19 vaccines within countries. The model takes into account multiple priority groups, vaccine types, and regional characteristics to propose fair distribution alternatives in a short time. The model minimizes deviations from fair coverage levels and sets minimum coverage thresholds to ensure equitable allocation to higher priority groups and regions. The research provides equity and effectiveness metrics and compares the model's performance to similar models in the literature. A comprehensive numerical study based on actual data from Turkey is conducted to illustrate the model's performance in practice.

Summary: The study presents a solution for the challenges in the vaccine supply chain through a robust optimization model, considering various costs and risks in the public vaccination program. Numerical experiments based on the vaccine supply chain in Kermanshah, Iran, show that the proposed model significantly reduces mortality risk, inequality in vaccine distribution, and total cost.

Summary: Equitable access to COVID-19 vaccines is crucial for ending the pandemic. Disparities in vaccine coverage exist both among low-income and high-income countries, mainly due to limited supply, unequal distribution, production constraints in low-income countries, weak health systems, vaccine hesitancy, and misconceptions. To address this inequity, efforts should focus on expanding COVAX, waiving intellectual property rights, technology transfer, and conducting mass vaccination campaigns.

Summary: With almost 11 billion COVID-19 vaccine doses administered, there are significant disparities in vaccination rates. Initiatives such as COVAX and AVAT were established to ensure equitable distribution, but differences remain. This review analyzes the initial vaccination efforts and the impact of different distribution initiatives, revealing inequities among countries of different income groups. Future efforts should focus on addressing these disparities and improving global vaccine distribution.

Summary: By surveying adolescents and their parents, we found that parental concerns about vaccine safety increased significantly before and after the availability of the COVID-19 vaccine. Social media negatively influenced opinions about vaccine safety. Demographic variables were associated with vaccination rates, highlighting inequalities in vaccine access. Most parents supported simultaneous COVID-19 vaccination with other vaccines. Addressing vaccine hesitancy is crucial for increasing COVID-19 vaccine coverage rates.

Summary: This study examines the accessibility to COVID-19 vaccination resources in two counties surrounding Newark, NJ in the New York Metropolitan Area. The study found clear spatial heterogeneity in accessibility to vaccine resources across different population groups. The introduction of county mass vaccination sites and a FEMA community vaccination center impacted accessibility patterns. Local health departments and the federal government played important roles in mitigating pre-existing inequalities during the vaccination campaign.

Summary: In the current world, firms face numerous challenges that can disrupt business continuity. The recent outbreak of the coronavirus has posed problems for supply chain networks, particularly in perishable product industries such as pharmaceuticals, dairy, blood, and food. Risk assessment is a valuable tool for mitigating the impact of the virus on these networks. This study utilized a decision-making trial and evaluation laboratory approach to evaluate the risks to perishable product supply chain networks during the pandemic. The analysis highlighted the importance of product perishability, unhealthy working conditions, supply-side risks, and work hours in influencing other risk factors. Competitive risks were found to be particularly susceptible during this era of the coronavirus outbreak.

Summary: The present study investigates a joint inventory-pricing control problem in a dual-channel supply chain network for deteriorating products under carbon tax regulations. A mathematical model is developed to maximize the total profit. The model is solved using a hybrid algorithm combined with the simulated annealing (SA) and Gradient descent search. The findings show that the developed model is concave. An increase in the deterioration rate reduces the total profit. Moreover, an increase in carbon tax leads the manufacturer to decrease the number of deliveries while increasing the amount of delivered products.

Summary: The asymmetric market power between a firm and its partners negatively affects the firm's financial performance. Building relationships with suppliers or customers that have matched market power is the best approach. The strength of the buyer-supplier relationship amplifies the negative impact of asymmetric market power, while the level of relationship embeddedness reduces its negative effect. Moreover, firm-specific institutional, industry, and regional economic heterogeneities also influence the financial impact of asymmetric market power.
