The spike protein is the part of the virus that it uses to penetrate human cells so that it can bind with the cells more effectively and cause infection. When the antigenicity changes, vaccines that use the new mRNA technology such as Pfizer-BioNTech cannot recognise the mutant variant such as the B1617 one. Only a vaccine such as Sinovac that has an inactivated virus “with all its seven antigens” can still produce an immune response even when one antigen of the active invading virus is affected by mutation, Dr Oon wrote. He added that the B1617 variant had successfully infected vaccinated frontliners and airport staff members, as well as school children in Singapore. “Pfizer is useless now and obsolete in the presence of mutations on (the) spike gene,” the message read.

在这个方面 有个叫harvard2bighouse的人 有一些很奇特的猜想
88% effectiveness
这是研发时已经知道变种了，还是歪打正着，还是忽悠人打疫苗啊？任何一种都细思极恐。
对，Az 比较低， pfizer 保护率还行
Mrna 是针对spike protein 开发出来的疫苗，只要变异不在spike protein上, 就不太会影响到疫苗的有效率。
有人猜spike protein 因为是binding site ， 变异几率相对低些。不过现在很难说
现在的变种突变的程度还没那么厉害呗
你这引得是某论坛网友写的帖子。。。
有link，引用也是link里的段落，你没事吧

对啊，之前印度人可真是回国度探亲相亲结婚一点不耽误，完全视疫情为无物
我周围的印度人只有一个去年年初去了dubai 其他的都很守规矩
其他疫苗后果不自负？
卧槽，太同意了。推特上好多新加坡华人真的从内心认为科兴更好的。。。那脑子跟被轮子活摘了似的
也很公平，小部份民意照顧到了又以法律規範責任界線
其他國家都只能是變種
祖國的名字 不能亂題
大家心裡有數
alpha 變種 英國 beta 南非 gamma 巴西 delta 印度 變種
alpha 英國 beta 南非 gamma 巴西 delta 印度
當然 祖國是 中文 就稱為 祖國病毒
你能核实这些人是真的新加坡人？
大外宣正在积极制造出新加坡人渴求科兴疫苗的假象。一个习总不敢打的疫苗。
哈哈可能因为不是印度自己engineer的，所以不会踩到尾巴
左右胳膊各一针，左右大腿各一针么？
辉瑞小白鼠你好
