Quercetin is an antioxidant, detox, and anti-inflammatory agent, which may help lower inflammation as well as reduce toxic effects. It has been argued that vaccines have potential risks of local and systemic inflammatory responses and toxic effects of synthetic nucleosides and components for vaccine delivery. Administration of substances such as Quercetin may then mitigate these effects. It has similarly been argued that substances such as Quercetin may reduce the efficacy of vaccines, which works in building an immune response to produce antibodies. Under this other perspective, the assumption of Quercetin should be avoided when receiving vaccines. The purpose of this paper is to analyze the information available to understand if Quercetin may mitigate the damage from novel coronavirus disease 2019 (COVID-19) vaccines, or also reduce their efficacy.

槲皮素是一种抗氧化剂、排毒剂和抗炎剂，可能有助于降低炎症并减少毒性作用。有人认为，疫苗具有局部和全身炎症反应的潜在风险，以及用于疫苗递送的合成核苷和成分的毒性作用。服用槲皮素等物质可能会减轻这些影响。同样有人认为，槲皮素等物质可能会降低疫苗的效力，疫苗可用于构建免疫反应以产生抗体。从另一个角度来看，接种疫苗时应避免假设槲皮素。本文的目的是分析现有信息，以了解槲皮素是否可以减轻新型冠状病毒病 2019 (COVID-19) 疫苗的损害，
