Well CMM has had his Covid booster shot! The timing has been great since he'd been off his chemo for a week due to low platelets, and although they are coming up, they're not high enough to go back on chemo this week, so it was kind of the ideal window to get the booster. (His previous two shots were during heavy duty chemo and he doesn't test positive for the antibodies, so he's the ideal candidate for the booster shot.) Hopefully his immune system will mount a better immune response this time.
