Just weighing in here about the booster. My cardiologist had mentioned she has heard reports from her patients that the booster, more than the initial vaccinations, can trigger PVCs. I was wary but went ahead and got the Moderna booster this week anyway. Happy to report no extra PVCs (beyond those I might normally have!) I know it's hard to draw conclusions from anecdotal stories, but I myself find comfort in reading about individual peoples' experiences, so I hope this reassures someone reading this. Aside from a slightly sore arm and shoulder, I feel great!
