Many here have already gotten their boosters. If you haven't, I would urge you to get it. Breakthrough deaths are not rare.
However, there may be a downside. I had very bad side effects from my initial 2 Modernas including 3.5" lymph node and worsening blood counts. I deliberately waited for the Moderna 50 mcg, eschewing the standard 100 mcg originals. Alas, the side-effects with the 50 mcg are just as bad.
We CLLers are stuck between a rock and a hard place because too many people in the US and UK refuse to vax and mask. I may have to opt for the MAB route if the situation does not improve 6 months from now.
