Is the potential damage to DNA the same for the Phizer and AZ shots. We hear everything about Phizer and Moderna but very little about AZ anymore. Many people in BC took AZ early on when we were told it was “safe” for a certain age group (I believe mid 50’s to early 60’s). Many got one AZ and then took a PZ or Mod for their second as the “science changed”within one month which showed that was “safe to mix and match” (though I do not believe there was ever any trials done to validate this claim). Is there anything g known about those who took only 2 AZ and no more shots or are long term studies not being done at all since it seems most of the original group is corrupted by mix match policy?
