Wow, wonderful news. 具体数据在这里：

“Of the 36,659 workers vaccinated, 379 tested positive after their first vaccine dose, with the majority of those individuals testing positive within two weeks of their first shot. After receiving both doses of the two-shot vaccine, 37 people tested positive, with the majority testing positive less than a week after their second dose. Only seven health workers tested positive 15 days or more after their second vaccination. ” 这个说明Pfizer or Moderna保护率在打完第二针两周之后接近100%！ 不知道这个研究是否有缺陷，是否需要等更长时间再看效果？
