Abstract Ensuring a more equitable distribution of vaccines worldwide is an effective strategy to control the COVID-19 pandemic and support global economic recovery. Here, we analyze the socioeconomic effects - defined as health gains, lockdown-easing benefit, and supply-chain rebuilding benefit - of a set of idealized vaccine distribution scenarios, by coupling an epidemiological model with a global trade-modeling framework. We find that overall a perfectly equitable vaccine distribution across the world (Altruistic Age-informed Distribution Strategy) would increase global economic benefits by 11.7% ($950 billion) per year, compared to a strategy focusing on vaccinating the entire population within vaccine-producing countries first and then distributing vaccines to non-vaccine-producing countries (Selfish Distribution Strategy). With limited doses among mid- and low-income countries, prioritizing the elderly who are at high risk of dying, together with the key workforce who are at high risk of exposure, is found to be economically beneficial. We further show that such a strategy would cascade the protection to other production sectors while rebuilding the supply chains. Our results point to a benefit-sharing mechanism which highlights the potential of collaboration between vaccine-producing and other countries to guide an economically preferable vaccine distribution worldwide.

While discussion of vaccine allocation has centered around who should be prioritized (e.g., health care personnel and the elderly), we argue that vaccines should also be allocated to jurisdictions (e.g., counties within the USA) with the greatest immunization thresholds needed for ending the epidemic. At the current rate of vaccine distribution (March 15, 2021), universal herd immunity in the USA could be reached in roughly 4.5 months. However, distributing vaccines according to where the virus spreads more easily (dense counties with high R0 values), herd immunity would be reached simultaneously in all counties almost two months earlier and would require roughly 40% fewer vaccine doses. Furthermore, under the current distribution strategy densely populated counties would reach herd immunity last, with negative epidemiological and socio-economic consequences. In sum, it would be more fair and efficient to distribute vaccines to jurisdictions that need them most to reach herd immunity.

AbstractPresent hopes to conquer the Covid-19 epidemic are largely based on the expectation of a rapid availability of vaccines. However, once vaccine production starts, it will probably take time before there is enough vaccine for everyone, evoking the question how to distribute it best. While present vaccination guidelines largely focus on individual-based factors, i.e. on the question to whom vaccines should be provided first, e.g. to risk groups or to individuals with a strong social-mixing tendency, here we ask if a strategic spatiotemporal distribution of vaccines, e.g. to prioritize certain cities, can help to increase the overall survival rate of a population subject to an epidemic disease. To this end, we propose a strategy for the distribution of vaccines in time and space, which sequentially prioritizes regions with the most new cases of infection during a certain time frame and compare it with the standard practice of distributing vaccines demographically. Using a simple statistical model we find that, for a locally well-mixed population, the proposed strategy strongly reduces the number of deaths (by about a factor of two for basic reproduction numbers of $$R_0\sim 1.5-4$$ R 0 ∼ 1.5 - 4 and by about 35% for $$R_0\sim 1$$ R 0 ∼ 1 ). The proposed vaccine distribution strategy establishes the idea that prioritizing individuals not only regarding individual factors, such as their risk of spreading the disease, but also according to the region in which they live can help saving lives. The suggested vaccine distribution strategy can be tested in more detailed models in the future and might inspire discussions regarding the importance of spatiotemporal distribution rules for vaccination guidelines.

Vaccination is one of the effective ways for protecting susceptible individuals from infectious diseases. Different age groups of population have different vulnerability to the disease and different contact frequencies. In order to achieve the maximum effects, the distribution of vaccine doses to the groups of individuals needs to be optimized. In this paper, a differential evolution (DE) algorithm is proposed to address the problem. The performance of the proposed algorithm has been tested by a classical infectious disease transmission model and a series of simulations have been made. The results show that the proposed algorithm can always obtain the best vaccine distribution strategy which can minimize the number of infectious individuals during the epidemic outbreak. Furthermore, the effects of vaccination on different days and the vaccine coverage percentages have also been discussed.

Penelitian yang dilakukan mempunyai sebuah tujuan untuk mengetahui bagaimana strategi di Swalayan Surya Gondang dengan menggunakan jenis pendekatan secara langsung atau lapangan (field research), sedangkan jenis penelitian adalah kualitatif. Data yang diperoleh berupa data primer dan sekunder, sebagaimana yang terdapat dalam metode pengumpulan data dengan cara wawancara dan telaah dokumentasi. Dalam menganalisis data, peneliti menggunakan teknik analisis data kualitatif. Dari hasil penelitian yang dilakukan oleh peneliti bahwa Swalayan Surya Gondang mempunyai 2 strategi untuk menarik minat konsumen (pelanggan) yaitu berupa penetapan harga yang ada pada POP (Point of Price) tidak sesuai dengan database komputer sehingga terjadi perubahan lafal ijab dan qabul. Strategi  selanjutnya  yaitu  berupa promo yang terdapat pada barang komoditas berupa promo diskon di mana telah ditemukan adanya ketidakjujuran terhadap barang yang mendapat promo diskon, yang ditemukan penutupan logo promo pada masa kadaluwarsa yang menyebabkan pihak konsumen (pelanggan) tidak megetahui kapan masa kadaluwarsa akan habis. Kata Kunci: Strategi, Penjualan Barang, Swalayan.ABSTRACT:The sales or marketing strategy is a target selection that determines the position of competition and mix in buying and selling transactions. In the strategy applied sales or marketing in supermarkets can be divided into several types; a) Product Strategy, b) Price Strategy, c) Distribution Strategy, d) Promotion Strategy. Surya Gondang Supermarket has two strategies that can be implemented, the price strategy in pricing in the form of POP (Pont of Price) and in the form of a promotion strategy for certain goods with the promo system in commodity goods. Pricing in the form of a Point (POP) that is contained in a commodity shop window where it is a price agreement between a supermarket and a customer. While the strategy that occurred in the promotion was implemented in the promo system divided into 10 kinds of promos (discounts, cheap, just 3 days, the beginning of the month, the end of the month, home care, beauty fair, kitchen fair, kids and baby fair, and excited).

The research conducted has a purpose to find out how the strategy in Surya Gondang Supermarkets uses the type of approach directly or in the field (field research), while the type of research is qualitative. Data obtained in the form of primary and secondary data, as contained in the method of data collection by means of interviews and documentation. In analyzing data, researchers used qualitative data analysis techniques. From the results of research conducted by researchers that Surya Gondang Supermarket has 2 strategies to attract consumers (customers), they are; in the form of pricing in the POP (Point Of Price) that is not in accordance with computer databases so that changes in lafadz ijab and qabul occur. The next strategy is in the form of promos contained in commodity goods in the form of discount promos where there has been a dishonesty of the goods that received a discount promo, which found closure of the promo logo on expiration which causes the consumer (customer) not to know when the expiration will expire.
