saab6212: 我上面放的 CNN 報導指出目前補打(第三劑)疫苗沒有確切的時間或需求(而且也沒有建議如此做)
Currently, "the need for and timing for COVID-19 booster doses have not been established. No additional doses are recommended at this time," the US Centers for Disease Control and Prevention notes on its website.
之前看到報導引述未來八個月或一年內可能需要補打(就是一年一度接種,跟流感疫苗一樣)
