1) About 15% of all pregnancies end in miscarriage so 12% is fine. 2) Dividing 100 by 800 as you did is utterly pointless because there are approximately 3,000 incomplete pregnancies. Those could all result in miscarriages tomorrow. They could not. The data is simply immature and it's useless to draw any conclusions from it other than "The vaccine doesn't immediately kill the mother or child".
