The sanctioning of different coronavirus vaccines (with some approved by regulators for public delivery, and others in the pipeline) has met with relief by many sections of the public and the government. However, partly due to the damages associated with the pandemic and the ensuing euphoria over vaccines’ arrival, some of the challenges are mostly being ignored or are not recognized. This paper identifies some pitfalls and drawbacks in vaccine delivery. We argue that the somewhat unique tension between the speed of vaccine delivery and its scale can create opportunities for corrupt behavior that are often at odds with effective means to check abuse. While data on instances of abuse will emerge over time, it is useful to point out different avenues of abuse so that some preventive government actions can be undertaken. Specifically, we argue that the potential for out of turn delivery of vaccines and the stockpiling by unauthorized agents creates incentives for corruption, with the public or bureaucrats initiating corrupt transactions. An understanding of the potential avenues for corruption should guide the formulation of appropriate corruption-control policies and similar challenges that will be faced by policy makers in addressing future pandemics.

对不同冠状病毒疫苗的批准（有些已获得监管机构批准用于公共交付，有些正在筹备中）让许多公众和政府部门松了一口气。然而，部分由于与大流行相关的损害以及随之而来的对疫苗到来的兴奋，一些挑战大多被忽视或未被认识到。本文确定了疫苗交付中的一些陷阱和缺点。我们认为，疫苗交付速度与其规模之间有些独特的紧张关系可能为腐败行为创造机会，而这些腐败行为往往与有效的防止滥用手段相矛盾。虽然滥用实例的数据会随着时间的推移而出现，但指出不同的滥用途径是有用的，以便可以采取一些预防性政府行动。具体来说，我们认为，疫苗的不按顺序交付和未经授权的代理人储存的可能性会刺激腐败，公众或官僚机构会发起腐败交易。了解腐败的潜在途径应指导制定适当的腐败控制政策和决策者在应对未来流行病时将面临的类似挑战。
