疫苗打莫德納的人也不能慶幸,昨晚看到李艷秋公開問衛福部幾個問題,其中最關鍵的是,美國CDC對莫德納打第二劑效用最好的時機是相隔4-6周,台灣擅自改成10-12周,李艷秋有附上原英文說明,她要求衛福部延後施打的依據為何?!這些事項我們一般民眾都還被瞞住,好在有人質疑,不然原本預估的94%保護力或許降低至AZ的70%,大家還不知道呢!

李艷秋確實有透過〈李艷秋的新聞夜總會〉臉書提出相關質疑。[見出處1]

但此訊息中所謂「台灣擅自改成10-12周」的說法與事實不符。

一、根據 WHO 於 2021 年 6 月 15 日更新的莫德納疫苗施打指引,WHO 確實已建議,對於高危險族群的(第一劑)疫苗覆蓋率還不夠高的國家,應該透過延長兩劑間隔至 12 週的方式,來專注於提高疫苗覆蓋率。[見出處2]

二、目前確實已有相關的科學研究顯示,若將莫德納的兩劑間隔時間延長到至少 9 週以上,反而能增加整體疫苗施打的效力並減少 COVID-19 的傳播、住院與死亡率。[見出處3]

三、以加拿大的做法為例,加拿大政府為了提高第一劑疫苗的覆蓋率,於 2021 年 3 月起,把所有已核准的疫苗(包括莫德納、輝瑞BNT、AZ 疫苗)的兩劑間隔時間皆延長為四個月。[見出處4、5]
