I am curious why you (your health authorities) don't run a trial first? Why would you not expect the Pfizer vaccine to have the same variant troubles as the AZ?

- _djo_ 6y agoThere wasn’t enough time for a full new trial, especially as the first phase was meant to be a trial in and of itself and was intended for crucial high risk individuals like healthcare workers. So the country had to rely on what data was available, which showed much better effectiveness against B.1351 from the Pfizer and J&J vaccines.
