Vaccine nationalism and its implications to vaccine supply were a huge concern globally when COVID-19 vaccines first became available in 2021. At the time, vaccine supply was limited and it was difficult for many countries around the world to get adequate supply of the COVID-19 vaccine to inoculate their people. At its most benign, vaccine nationalism delayed the access of poorer countries to vaccines that are widely considered as the long-term solution to the COVID-19 pandemic. Poorer countries needed to resort to diplomacy to wrangle early access to vaccine supply from vaccine-producing countries like the United States, the United Kingdom and others. In particular, Philippine President Rodrigo Duterte leveraged his country's Visiting Forces Agreement (VFA) with the United States and the need for Filipino nurses by countries like the United Kingdom and Germany to secure early access to COVID-19 vaccines. It all seems trivial now (in 2022) because of better global vaccine supply, but in 2021 when countries scrambled for access to scarce COVID-19 vaccines, Rodrigo Duterte leveraged the Philippines' assets to gain early access to vaccine supply.

Renewable energy (RE) is essential to comprise sustainable societies, especially, in rural villages of developing countries. Furthermore, application of off-grid RE systems to health care can improve the quality of life. In this research, a RE-based vaccination supply management system was constructed to enlarge the cold-chain in developing countries for the safe storage and delivery of vaccines. The system was comprised of the construction of RE plants and development of vaccine carriers. RE plants were constructed and connected to health posts in local villages. The cooling mechanism of vaccine carriers was improved and monitoring devices were installed. The effect of the system on vaccine cold-chain was evaluated from the field test and topographical analysis in the southern village of Nepal. RE plants were normally operated for the vaccine refrigerator in the health post. The modified vaccine carriers had a longer operation time and better temperature control via monitoring and RE-based recharging functionality. The topographical analysis estimated that the system can cover larger region. The system prototype showed great potential regarding the possibility of a sustainable and enlarged cold-chain. Thus, RE-based vaccine supply management is expected to facilitate vaccine availability while minimizing waste in the supply chain.

This study conducted a survey using Google Survey targeting 415 college students over the age of 20 to investigate college students' perceptions of the COVID-19 vaccine. As a result, the average result of 'I think the COVID-19 vaccination is necessary' for herd immunity was 3.90, and 65.8% of the 'necessity of vaccination' recognized the 'necessity of vaccination', but 35.4% negatively evaluated 'the safety of the vaccine'. showed. As for the intention to vaccinate against COVID-19, 34.7% said 'I will vaccinate as soon as the order arrives'. This showed that the current COVID-19 vaccination is not positive. As the reasons for not wanting to be vaccinated, 65.3% answered 'adverse reaction to the vaccine' and 25.8% 'distrust of the vaccine itself'. In addition, they perceived the vaccine supply between developed and underdeveloped countries as unequal, and the average was 3.94, indicating that they were afraid of adverse reactions to the COVID-19 vaccine. Therefore, in order to more effectively acquire information about the COVID-19 vaccine, research, platform development, and education on publicity methods through the media frequently used by college students are required.

The inventory routing problem (IRP) is an important area of Supply Chain Management. The objective function of IRP is the sum of transportation cost and inventory cost. We propose an Artificial Immune System(AIS) to solve the IRP. AIS is one of natural computing algorithm. An hyper mutation and an vaccine operator are introduced in our research. Computation results show that the hyper mutation is useful to improve the solution quality and the vaccine is useful to reduce the calculation time.

Annual epidemics of seasonal influenza occur during autumn and winter in temperate regions and have imposed substantial public health and economic burdens. At the global level, these epidemics cause about 3-5 million severe cases of illness and about 0.25-0.5 million deaths each year. Although annual vaccination is the most effective way to prevent the disease and its severe outcomes, influenza vaccination coverage rates have been at suboptimal levels in many countries. For instance, the coverage rates among the elderly in 20 developed nations in 2008 ranged from 21% to 78% (median 65%). In the U.S., influenza vaccination levels among elderly population appeared to reach a "plateau" of about 70% after the late 1990s, and levels among child populations have remained at less than 50%. In addition, disparities in the coverage rates across subpopulations within a country present another important public health issue. New approaches are needed for countries striving both to improve their overall coverage rates and to eliminate disparities. This review article aims to describe a broad conceptual framework of vaccination, and to illustrate four potential determinants of influenza vaccination based on empirical analyses of U.S. nationally representative populations. These determinants include the ongoing influenza epidemic level, mass media reporting on influenza-related topics, reimbursement rate for providers to administer influenza vaccination, and vaccine supply. It additionally proposes specific policy implications, derived from these empirical analyses, to improve the influenza vaccination coverage rate and associated disparities in the U.S., which could be generalizable to other countries.

Purpose: This study aimed to identify factors associated with nurses' vaccination acceptance in the initial stage of coronavirus infectious disease 2019 (COVID-19) vaccination in Korea. Methods: This cross-sectional study collected data from hospital-level or higher medical institutions from May 5 to May 7, 2021 with a total of 368 nurses via an online survey. Multiple regression analysis was used to identify factors associated with vaccination acceptance. Results: The acceptance of COVID-19 vaccination had an average score of 4.28 ± 0.80 out of 7 points. Among the sub-areas of acceptance, the safety of the vaccine exhibited the lowest score (average, 2.80 ± 0.83). The factors related to COVID-19 vaccination acceptance in nurses were age (over 40 compared to under 29) (β = .16, p = .008), experience (more than 11 years compared to under 5) (β = .16, p = .010), the absence of a preferred vaccine (β = -.14, p = .004), and educational background (a master's degree or higher compared to a bachelor's degree or lower) (β = .12, p = .042). Conclusion: In the initial stage of COVID-19 vaccination, nurses believed that the COVID-19 vaccine was important and that people should be vaccinated, but had concerns regarding the safety of the vaccine. Older age, more experience, the absence of a preferred vaccine, and a higher educational background were associated with higher acceptance of COVID-19 vaccination. Therefore, more active education on the necessity and value of vaccination for young people is required at the individual and socio-cultural level, and a sufficient supply of preferred vaccines at the national level is needed.

Background: 8,000 children in North Korea died before they reached the 1 year after births in 2013. The high mortality rate of children under five years of age is mainly caused by infectious diseases and malnutrition. The need for national pediatric immunization and supply of vaccines will be vital when the abrupt reunification occurs. Objective: The purpose of this study is to scrutinize the pediatric immunization coverage of North Korea. Additionally it is to estimate the amount and the costs needed to vaccinate. Methods: The target population is the children of North Korea. The method is based on a pre-survey and an interview of North Korea defectors. The target interviewees searched for are as follows; doctors, teachers, and others. The interview includes questions on mortality rates and immunization coverage. The analysis is largely based on the statements of the health care providers within the selected group. Results: The interviewees are 8; 7 female and 1 male. The birth years range from 1956 to 1982. 3 out of 8 are former health care providers; a doctor, a pharmacist, and a nurse. The morbidity rate of infectious diseases exceeds the data from WHO. The immunization coverage is nearly 0% after 1980s. In order to ensure the welfare of North Korean children, at least 8,234,000 vaccine doses, requiring over 105 million U.S. dollars, are needed. Conclusion: The morbidity rate of infectious disease in North Korea is conspicuous. The preparation for supply and expenditure of vaccines is vital.

To overcome the ongoing COVID-19 pandemic, vaccination campaigns are the highest priority of majority of countries. Limited supply and worldwide disproportionate availability issues for the approved vaccines, together with concerns about rare side-effects have recently initiated the switch to heterologous vaccination, commonly known as mixing of vaccines. The COVID-19 vaccines are highly effective in the general population. However, none of the vaccines is 100% efficacious or effective, with variants posing more challenges, resulting in breakthrough cases. This review summarizes the current knowledge of immune responses to variants of concern (VOC) and breakthrough infections. Furthermore, we discuss the scope of heterologous vaccination and future strategies to tackle the COVID-19 pandemic, including fractionation of vaccine doses and alternative route of vaccination.
