【橙新闻】新冠重症月增86宗 專家籲速補疫苗防線 香港疫情呈波動上升趨勢，據衞生防護中心最新通報，過去四周累計錄得86宗新冠重症個案，包括81名成人及5名兒童，其中30宗死亡病例涉及長期病患長者。病毒學界關注到JN.1變異株已佔本地個案72%，較上月提升23個百分點。 「現有疫苗對防重症效力仍超75%，接種三劑者住院風險降低89%。」港大醫學院公共衞生學院病毒學講座教授潘烈文強調，當前感染潮源於免疫衰減而非病毒增強。 疫苗接種數據顯示，60歲以上群組第四針覆蓋率停滯在58%，18至59歲工作人群加強劑接種率更不足四成。醫管局已啟動急症室分流機制，對出現血氧低於94%或持續高熱患者實施優先處置。 值得注意的風險點在學童群體，5宗兒童重症中3宗未完成基礎免疫。教育局證實正與學界研議，考慮將疫苗接種證明納入新學年入學註冊要件。呼吸系統科專科醫生梁子超提醒，暑期跨境人流增加可能加劇病毒傳播，建議出入境高峰前完成疫苗補種。
