这位医生自己说的：OTTAWA - Dr. Joss Reimer, medical lead for Manitoba’s Vaccine Implementation Task Force, says that new vaccine recommendations from the National Advisory Committee on Immunization on mixing mRNA vaccines will be a form of trial and error.
“Well in some ways, during a pandemic everything we do is a big human experiment,” she said in an interview with CTV’s Question Period airing Sunday. “Because we're all having to learn together at the same time, about what works the best.” Reimer says that mixing and matching vaccines is a not a new practice in the medical field.
“We have a lot of experience doing this in the past,” said Reimer. “And what these small trials did is reassure us that it doesn't look like the COVID vaccines will be different than our previous experience.” 看不懂英文可以用翻译，别指鹿为马，混淆是非，显不出你智商高，只能说明你又蠢又坏。
