Last Saturday I thawed and used a vial that had been in the deep freezer for exactly one year. I had my second shot yesterday and I have to say I cannot tell any difference in efficacy to my unfrozen vial. I originally froze it because husband had got prescription and then decided he wasn’t going to follow through. (He did eventually start though). I froze a bit more after the panic buys as well.
