My wife was pregnant when the vaccines came out and we had to make a decision on whether to get her vaccinated, which might provide COVID protection to our newborn, or to avoid the risk of a relatively new vaccine and pregnancy complications. This was further complicated by the fact that initially our doctor advised against talking the vaccine while pregnant, and then suddenly flipped to strongly encouraging us to take it without any new evidence - pressuring us by warning that our child might catch COVID in the hospital at birth. All this complicated still more by the fact that I know the medical establishment in the US repeatedly lied and got major things wrong with respect to COVID.
COVID, and the vaccine, are very difficult decisions for people. I can't imagine the loss for this family or how horrible it would be to try to make the best decision to keep your child safe and wind up with this - against all odds.
I found it interesting that there's such a wide discrepancy between myocarditis numbers in the US versus the Nordic countries. I wonder what phenomenon explains that.
