I'm wondering if anyone in this group has discussed with their doctor the possibility of taking the J&J vaccine which - even with the very serious, rare TTS risk - is not an mRNA vaccine. Or has anyone discussed the new plant-based vaccine with their cardiologists. It is still in trials and not known when/if it would be available, but it could perhaps be an alternative. https://www.yahoo.com/lifestyle/everything-know-plant-based-covid-130000446.html
I also developed tachycardia/flutter some weeks after dose two of pfizer and have since had to have two ablations. There are many reasons, other than the vaccine, that it could have been caused, but obviously, I am feeling cautious.
