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.
This other linked above is the Pfizer clinical trial report: STN 125742_0_0 Section 2.7.4 summary-clin-safety.pdf
Thanks for your correction to my post 28.
So we don't have any published data on the effects of the vaccine on pregnant women.
