Only Comirnaty has a safety signal for spontaneous abortion.

It is curious that Vaxzevria has the highest incidence of thrombosis, but the lowest incidence of Cardiac symptoms. They must be two distinct processes. What causes the thrombosis cannot be what causes the heart issues.

Looking at ALL uterine disorders, the pattern continues with Comirnaty showing a significantly higher level of Uterine symptoms.

Because Comirnaty showed a much higher incidence of menstrual disorder, I decided to look at the effects on ovulation. As expected, Comirnaty also had much higher incidence of ovulatory disorders. Though these effects were shared by Tozinameran and Spikevax, the scores were much smaller. Curiously, Vaxzevria showed no effects (for lower confidence interval > 1)

It looks as if Comirnaty was focused on reproductive effects to do with the menstrual cycle. Not only does it have a larger number of different symptoms, but it also has much higher scores for each symptom. Vaxzevria shows a conspicuous absence of this symptom.

It looks to me that VAXZEVRIA was the thrombosis jab. The other brands were not focused on this. The number is the lower confidence limit of PRR.

In contrast Vaxzevria is dominated by thrombosis symptoms -

This is a continuation of the table above. As you can see - menstrual disorder occurs and also there is an effect on ovulation.
