AstraZeneca’s prophylactic drug Evusheld, which has been cleared for use in Hainan, is currently the only COVID-19 prophylactic drug in the world. The treatment consists of two injections, and its total price is 13,300 RMB. Several studies have shown that Evusheld has a strong preventive effect and can significantly reduce lung inflammation, however the effect lasts for a period of around only 6 months. People with a weaker immune system are advised to choose preventive treatment under the guidance of medical professionals.
