In the first two months of 2021, the production of COVID-19 vaccines has suffered setbacks delaying the implementation of national inoculation strategies. These delays have revealed the concentration of vaccine manufacture in a small club of producer nations, which in turn has implications for the degree to which cross-border value chains can deter more aggressive forms of Vaccine Nationalism, such as export curbs. This paper documents the existence of this club, taking account of not just the production of final vaccines but also the ingredients of and items needed to manufacture and distribute COVID-19 vaccines. During 2017-19, vaccine producing nations sourced 88 percent of their key vaccine ingredients from other vaccine producing trading partners. Combined with the growing number of mutations of COVID-19 and the realization that this coronavirus is likely to become a permanent endemic global health threat, this finding calls for a rethink of the policy calculus towards ramping up the production and distribution of COVID-19 vaccines, its ingredients, and the various items needed to deliver them. The more approved vaccines that are safely produced, the smaller will be the temptation to succumb to zero-sum Vaccine Nationalism.

Social Networks, Drug Injectors' Lives, and HIV/AIDS recognizes HIV as a socially structured disease - its transmission usually requires intimate contact between individuals - and shows how social networks shape high-risk behaviors and the spread of HIV. The authors recount the groundbreaking use of social network methods, ethnographic direct-observation techniques, and in-depth interviews in their study of a drug-using community in Brooklyn, New York. They provide a detailed documentary of the lives of community members. They describe drug-use, the affects of poverty and homelessness, the acquisition of money and drugs, and social relationships within the group. Social Networks, Drug Injectors' Lives, and HIV/AIDS shows that social networks and contexts are of crucial importance in understanding and fighting the AIDS epidemic. These findings should revitalize prevention efforts and reshape social policy.

This book is a collection of 13 innovative papers describing the state of the art and the future perspectives in solid-phase extraction covering several analytical fields prior to the use of gas or liquid chromatographic analysis. New sorptive materials are presented including carbon nanohorn suprastructures on paper support, melamine sponge functionalized with urea–formaldehyde co-oligomers, chiral metal–organic frameworks, UiO-66-based metal–organic frameworks, and fabric phase sorptive media for various applications. Solid-phase extraction can be applied in several formats aside from the conventional cartridges or mini-column approach, e.g., online solid-phase extraction, dispersive solid-phase microextraction, and in-syringe micro-solid-phase extraction can be very helpful for analyte pre-concentration and sample clean-up. Polycyclic musks in aqueous samples, 8-Nitroguanine in DNA by chemical derivatization antibacterial diterpenes from the roots of salvia prattii, perfluoroalkyl substances (PFASs) in aater samples by bamboo charcoal-based SPE, parabens in environmental water samples, benzotriazoles as environmental pollutants, organochlorine pesticide residues in various fruit juices and water samples and synthetic peptide purification are among the applications cited in this collection. All these outstanding contributions highlight the necessity of this analytical step, present the advantages and disadvantages of each method and focus on the green analytical chemistry guidelines that have to be fulfilled in current analytical practices.
