When I got my boosters with Novavax ..
at Mayo they opened a vial as I was first..they had a set time to use it during the day..then had to destroy. What was not used..same thing for he MRNA shots..
if Novavax gets a single syringe dose approved that can stay on the shelf so to speak for 10 months, let’s say another huge advantage! Using them we needed one of the time hasn’t been talked about
