这个是整个西方最强的组合，疫苗效果依然远远差于中国疫苗...不容乐观

Pfizer reported safety data for 5,664 people ages 18 to 64 and 1,816 people ages 65 to 85 who received one dose. In the younger group, 38% reported fatigue afterward, while 35% reported headache and 16% had chills. Eleven percent or fewer suffered joint pain, diarrhea or chills. The side effects percentages were lower among the older age group.

After the second dose, 36% of trial participants aged 18 to 64 reported fatigue, while 28% reported a headache and 18% reported muscle pain. Again, the data were blinded between placebo and the vaccine candidate.

Most side effects after the second dose were mild to moderate, but some participants did experience severe or grade 4 side effects, according to the presentation. There were more severe side effects after the second dose as compared with the first dose, even though a smaller number of participants—1,682—were in that group.

是的， 是一种比较热门的mRNA 疫苗技术， 如果搞成， 生产速度快成本很低， 蛋是： 从来没有在病毒上真正大范围成功的先例， 这种超过1/3 接种患者大面积副作用的结果放在以前， 3期直接终止。。。不过， 现在非常时期，老川急眼压迫fda 批准， 只要不死人或许还真批准呢。
