There is an important distinction that you're missing and is being deliberately obfuscated in how they conducted and determined' the results of the study. Ie - 'This is because, of the 827 pregnancies that were completed, 700 (or 86%) of the women had received a dose of the Pfizer or Moderna Covid-19 vaccination during the third trimester. Because miscarriages are regarded to occur prior to week 20, it is impossible to have one during the third trimester of pregnancy, which runs from weeks 27 to 40. This means that only 127 women received the Pfizer or Moderna Covid-19 vaccine during their first or second trimester, with 104 of them miscarrying. As a result, the rate of miscarriage is 82 percent, not the 12.6 percent reported in the study’s conclusions.' So the true results are as stated by OP.
