The pdf file of the Pfizer Safety report (5.3.6 Cumulative Analysis of Post-Authorization Adverse Event Reports...) posted at the link showed some high miscarriage, or still-born, events associated with the pregnant cohort in their vaccine trial.
Table 6, Page 12.
The data could have certainly been summarized more clearly, but what I read:
274 pregnant cases. 23 miscarriages ("spontaneous abortions"), 4 other deaths (still-born?); 5 "outcome pending" (?? I don't know what this means); and 238 with 'no outcome provided'.
So, at a minimum there was a 10% miscarriage, or stillborn, death rate amongst the pregnant women that were subjected to the Pfizer shots. I believe the 'typical' rate for such deaths in the United States is 1% -- so the Pfizer cohort apparently experienced a 10x higher fatality rate than the norm. And that is assuming that "no outcome provided", and 'outcome pending' turned out to mean 'successful delivery'.
That is NOT the Pfizer clinical trial report. It's right there in the title, (the Post-Authorization) report. It is data extracted by Pfizer from the VAERS database from December 2020 to February 2021. There is no data in that report which shows the number of people who were vaxxed.
