全球飽受新冠疫情肆虐，前後已累計近2億人感染，然而先前的「大魔王」印度Delta變種病毒，號稱傳染力又強又快，且即便完成疫苗接種者也無法完全抵抗，但近日竟又驚傳出現「哥倫比亞變異株」，造成各國人心惶惶，再釀一波疫苗搶打潮來再增強保護力，只是沒想到，未來將出現的這個強大變種株，「恐讓現今所有疫苗都失效」，完全無解藥。
根據英國政府「緊急情況科學顧問小組（SAGE）」在7月26日發表的報告指出，病毒幾乎不太可能根除，因此他們非常相信新變異株會持續出現，且隨著病毒突變的一點一點累積，最終恐會出現讓「所有疫苗都失效的變異株」，難道被視為疫情「唯一解方」的疫苗，也沒用了嗎？
報告提及，全球各牌疫苗在過去幾個月以來，逐漸發現對抗變異株方面，保護力都有不同程度下降，且部分變異株在疫苗普及前就已漸漸出現，以致於隨著疫苗普及，可能再進而產生傳播力更強的變種病毒，因此報告建議，各國政府應盡可能做好防疫，減少變異株對現有疫苗產生耐藥性，特別是減少「已接種疫苗個體」的染疫尤為重要，這樣才能防堵病毒再次變異。
不過，SAGE這份報告並未經其他醫療相關組織審查，且研究處於早期階段，目前仍尚未證明會使所有疫苗失效的變異株已出現，但從歐美國家已廣泛施打疫苗之下卻無法阻擋變異病毒蔓延來看，此報告依舊不可輕忽，專家正直言「這是場疫苗與人類的競速賽」，科學家們不斷研發全新技術，但病毒每分每秒都在變異，想要終結疫情恐還有很長的路要走。
