mRNA vaccine side effects on long term health are the talk of the town nowadays, and sources of information are plentiful enough, but I'm finding NOTHING on long term effects from J&J / Janssen (or AstraZeneca).
We've all heard of the dreaded thrombotic thrombocytopenia issues that occurred within 30 days of J&J / AZ administration, but if one makes it past the danger zone for this, are there any further worrying long term issues being seen with the adenovirus vector vaccines?
I know that spike generated from either vaccination or infection has adverse effects on vascular endothelium. Do we know if J&J / AZ generate more spike than mRNA, or for a longer period of time? Is there the same immune suppression with J&J / AZ as we see with mRNA?
I recall seeing data on all cause mortality being lower for J&J (and AstraZeneca) vaccinated, compared to mRNA a while back, but am having trouble finding any other info on long term effects with the adenovirus vector vaccines.
I expect since AstraZeneca was a similar (and more widely used) adenovirus vector vaccine, any long term effects from A/Z might also apply to J&J, but again, I can't find any long term issues associated with A/Z either.
Any help with this would be greatly appreciated!
