I'm pretty sure I have made it clear and many Dr's have that Covid is far more likely the cause than any vaccine. The infection attacks the venous and arterial system, including post recovery. It causes massive metabolic issues in many who have recovered and can continue to cause havoc for years the data has shown. It causes massive inflammation in the body, and again it can last for a long time post recovery. With this being a novel virus, it hit the majority of the population in less than 18 months, which leads to a much larger percentage of people with these issues than a typical illness. Hell, it was so transmissible it nearly wiped out the flu for a whole year. This was all over the world, not just in the US. And yes, we were still testing for it. The data is available as it always has been on state and government public health sites.
Plus, you can get it, not know you have it, and still have issues. You can get it multiple times a year due to how many mutations were occuring because of the rapid spread, especially if you were not vaccinated and in some cases even if you were. I know many doctors who treated patients who had it multiple times, even with PPE on. It's like a really good offense in the NFL, you can slow them down but it's almost impossible to stop.
All of this data is out there. The cardiovascular issues post recovery are probably the worst. Many have arrhythmias they never had before being infected. The crazy thing is this isn't unique to Covid. Many viruses and even bacterial infections due very similar things.
My father died of an extremely rare clotting disorder he had no idea he had called antiphospholipid syndrome or APS. He had the catastrophic version where you have clots in four or more different organs at the same time and onset is extremely rapid. His clotting event was likely triggered by an infection post recovery. It's one of the huge reasons I learned so much about Covid and became a community advocate, especially in regard to transparency of the testing, hospital, and death data. In the beginning, we were getting none of that and I had to track it myself and demand that SCDHEC get their shit together. Because hell, if I could do it, they sure as hell could.
With all of that being said, I'm sure the vaccine has caused some of the events, as it was always a known risk. However, all of the data points to it being much safer than getting Covid, which means the benefits outweighed the risk. One thing this has made me understand is there are so many people who simply don't understand how science works and surely didn't pay enough attention in science class. Science is about asking questions though, so I get it. However, the data set is pretty clear and will only get clearer the further we are out from it. Maybe it will change, but I wouldn't bet on it. The way mRNA vaccines work, long term effects are just highly unlikely.
