I had gotten the flu one back in early October as well. We waited on the new version of the Covid vaccine until late October; indeed I had gotten mine precisely one day before Memsahib was sent home, starting all this. Kind of a waste in retrospect as the vaccine had no time to work before I got nailed.

Now that we both have had the latest and greatest, they told her she might just as well skip her's simply because the same antibodies have been now generated.

Ah, virology!
