Summary

Urgent vaccine development plus the characteristics of the coronavirus have caused the relatively more safety problems in COVID-19 vaccines than other classic vaccines and unavoidably raises more concerns among those who accept or consider to be vaccinated. Mulberry juice consists of a large amount of anthocyanin. The abnormally high interleukin-17A level is frequently seen in patients with inflammation status or diseases with inflammation features. Some specific anthocyanins can reduce cyclooxygenase and nitrogen oxide, and the pharmacological effect of the major anthocyanin in mulberry juice imitates that of interleukin-17A antagonists. These features make mulberry juice a potential crude material for reducing inflammation and pain induced by COVID-19 vaccinations. The investigators propose a randomized control trial to explore the dose-response effects of three different volumes of mulberry juice on the incidence and severity of COVID-19 induced side effects. The findings should be helpful for nutrition supplementation in COVID-19 vaccinations and may improve public coordination of COVID-19 vaccinations.

Mulberry juice

Mulberry is a common macrophanerophyte that can be found in fields or farms. Mulberry fruits contain a large amount of anthocyanins and a relatively small amount of pro-anthocyanins. The plant is easy to grow and the fruit price is low compared with other types of plants producing anthocyanins, and thus a reliable source for anthocyanin supplements. Current laboratory evidence has shown that specific anthocyanins can reduce inflammation status, and potentially thrombosis. One of the enzymes inhibited by specific anthocyanins is cyclooxygenase which catalyzes the synthesis of prostanoids, including thromboxane and prostaglandins. Moreover, a critical study has shown that cyanidin 3-O-glucoside, the main anthocyanin in mulberry fruit, is an allosteric regulator of interleukin-17A.
