I like to check things for myself. The miscarriage rate in the Pfizer trial was not 44%.

Naomi Wolf's group used this file from the Pfizer FOIA:
pdata0916.s3.us-east-2.amazonaws.com/pdocs/070122/1…

It has this table at the end of the file listing total of 50 pregnancies "after dose 1" in the trial.

There are 22 line items in the file showing miscarriages. But they are from two different tables.

16.2.7.4.1 shows all adverse events.
16.2.7.5 shows serious adverse events.

The 11 miscarriages are in BOTH tables, so the 22 was a double count.

If we go back to the table of 50 pregnancies and mark the miscarriages we find only 3 of the 11 subject IDs. Presumably the other 8 were pregnant before dose 1. But we don't have the denominator for that to figure a rate.

So really all we can say is that at the timepoint when the file was generated there had been 11 miscarriages after Pfizer vaccine.

To further clarify, we cannot say 22% because it's not 11 out of 50. It's only 3 out of 50; the 11 is out of an unknown denominator.

I found a potential 12th miscarriage in the file.

There are also about 83 subjects with "exposure during pregnancy" line items. But not all the miscarriages have that line, so I'm not sure we can try to use that as a denominator.
