After yesterday's 2nd Pfizer shot my wife just asked me to bring her tea in a smaller cup because the regular mug was too heavy to lift. It will be a rough day or three for her. She likely (it was impossible to get tested, then testing wasn't reliable/didn't matter) had Covid back in January 2020 that lasted with low level symptoms for nearly a year. I had zero effects from my first Moderna, second one coming in a few days, crossing fingers.
