前两天看到这个了，新的双价booster跟老booster没区别。。。 Scientists at Columbia University in New York City found the new boosters did not produce a better antibody response in humans against BA.5 than the first-generation vaccines. A separate study by scientists at Harvard essentially came to the same conclusion. The studies indicate that the new boosters do not perform better than the old shots, though they are also probably not worse, said Dr. Paul Offit, a member of the FDA’s independent vaccine advisory committee. In other words, vaccine recipients probably get the same level of protection that would come from a fourth dose with the first generation shots, he said.

其结论是：完整接种疫苗后感染一次，免疫系统会有记忆，比较牢靠。。。
咱顶着钢盔等医界达人狂喷。。。
您这裸奔太牛了.... 防不了感染 至少防重症啊
可是政府继续捧mRNA疫苗，说新的二价mRNA疫苗 great，需要funding推广让每个美国人都打上一针。
其实小孩子打疫苗的好处vs 不打没有任何区别。我觉得不打也行吧
小孩重症的本身也很少吧
不用说疫苗防重症可能是个传说，即使是真的，不要忘记了，小孩子感染covid几乎无重症。
哪里有数据支持防重症的？
大人群数据是小孩重症少 可是身边好几个小娃2-5没打疫苗 结果都病的很厉害.....有个1岁的 被nanny（出去浪）传染 结果呼吸困难 进icu.... 我算疫苗党 大家不用和我争 :)
1岁左右小孩各种疫苗每隔几个月就扎一次，免疫系统本来就过载了。
一直强调中和抗体，就是因为没有任何别的证据啊。现在你说看中和抗体也不行，不是砸人饭碗吗
如果只是记忆的话，流感打过几年是不是就根本不用打了？每年的流感疫苗都是cover好几种流感病毒
八只老鼠不能白死不是？
对普通人而言，流感疫苗本来就不用打，不是嘛。多少人活了半辈子，从不打流感疫苗，活的好好的。
