The future of vaccinations against COVID and other viruses will probably mimic what has already happened with computers. Symantec and other security companies constantly monitor the environment for potential threats. Once a new virus is identified, the antivirus software gets updated and all computers instantly are immune to it. With the new mRNA technology, new vaccines can be developed in a matter of a few days. So the vaccinations will take much shorter time than what’s possible now.
美国药厂辉瑞(Pfizer)今(25)日宣布,该公司已开始研究施打第三剂新冠疫苗是否增强功效,这是预防变种病毒策略的一部分。
《美联社》报导,尽管卫生部门指第一代武肺疫苗仍然有效对抗变种,但疫苗生产商已开始做下一步准备,以防出现抗药性更高的变种病毒。
辉瑞宣布已展开研究第三剂增强疫苗对预防变种病毒的影响,将向去年参加美国初期试验的144志愿者施打第三剂疫苗。
研究旨在确定在施打前2剂疫苗后的6到12个月内再注射一次补充疫苗,能否增强接种者的免疫力,以抵御突变病毒。
辉瑞及其德国合作伙伴BioNTech也正在调整其疫苗配方。2家公司正在与美国和欧洲监管机构讨论一项研究,评估更新后的疫苗剂量是否能抵抗变体种,例如在南非首次发现的变体病毒。
