The avg phase 3 trial size is far smaller than the Pfizer or Moderna trials. Less than the normal max of 5,000 compared to 30,000+.
To find a 1 in 50,000 or 100,000 problem it would take several hundred thousand in a trial. And that doesn't happen
Phase IV is where the rare conditions are found. That is where it ultimately was shown.
