The real virus does not stay confined to your lungs, nor even mostly confined to your lungs
Of course not - but it is a long way from the blood and the heart.
That's simply not true. COVID caused a 30% increase in heart attack deaths among young adults during the first two years of the pandemic, with undiagnosed myocarditis believed to be the primary culprit. Myocarditis and pericarditis are, respectively, inflammation of the heart muscle and the area around it, caused by an immune response to an infection.
So COVID absolutely can get into your blood, can infect blood cells, and can spread anywhere in your body. It isn't guaranteed to reach your heart, and in fact, serious heart complications are relatively rare, but it can, and COVID-infection-induced myocarditis and pericarditis are both well-documented at this point.
Also, I think you're also misunderstanding how intramuscular injection works. The vaccine isn't put into your bloodstream like an IV. It is put into a muscle. And unlike the virus, which is self-replicating and can move around your body over time, the vaccine infects a cell once and produces output for a specific amount of time before it self-destructs, so unless you get very unlucky and end up with some of the vaccine getting somewhere that it doesn't belong, the overwhelming majority of the vaccine stays confined to the muscle into which it is injected, as do most of the spike proteins. To the extent that it spreads, it mainly ends up in the local lymph nodes. The amount that ends up in random parts of your body is normally very small.
That's why the statistical risk from the virus is considerably higher than the risk from the vaccines. Even though your immune system is attacking those foreign proteins, it almost never is happening in your heart with the vaccine, whereas it is much more likely to be happening in your heart with a natural infection, and that risk increases by something like 11x if you have never been vaccinated because it takes longer for your immune system to realize that it needs to kick into gear and attack the virus.
Why do you think one of the most common first symptoms of COVID (*before* respiratory symptoms) is diarrhea?
Because mucus full of the virus goes down the throat. Epithelial spreading from top to bottom.
If the actual virus was getting to your heart muscles it's already a very serious infection, even if it is relatively asymptomatic.
Yes, that's certainly one way that it can get there, but once something is in your nose, gut, or lungs, the barrier to your bloodstream is minimal. After all, if that were not the case, you would not be able to breathe or absorb nutrients from food.
Either way, the point of that comment wasn't that it gets to your digestive system through the blood, but rather that it doesn't stay mostly confined to your lungs, and can spread anywhere in your body. The lungs aren't really even the primary target/symptom area at this point.
The lungs are the direct conduit to the bloodstream, of course, but what do you think causes the clotting? The binding of the spike protein to the ACE2 receptor.
Actually, no. It is believed to be caused by the virus attacking and damaging the epithelial cells that line the blood vessels. The ACE2 receptor just happens to be how the virus gets into those cells, and that's also what makes it sometimes attack the heart muscle in young people and cause myocarditis.
That, coupled with lower bloodstream involvement in general, explains why there's no sign of increased heart attacks or strokes after mRNA-based COVID vaccination. The shots that did potentially cause clotting issues were the ones built around attenuated viruses.
If you forgot the main point I was making, it's that the vaccine platform isn't the cause of the clotting - it's the proteins it produces that mimic the virus structure.
Except it isn't, as I said above.
But even if what you're saying turned out to be correct, the virus would still do exactly the same thing, but with an actual virus behind those spike proteins. So instead of just causing your body to temporarily act like it has gotten a low dose of an ACE inhibitor and have slightly lower blood pressure, it also attacks the cells it hits and kills or damages them. Instead of rare cases of mild myocarditis from those spike proteins interacting with the heart muscle that mostly resolve on their own, you have cases of acute myocarditis often resulting in death.
Any time you have a vaccine whether weakened or mRNA, there's a chance that the symptoms caused by the virus will also be caused by the vaccine, just typically with much lower severity. And the whole point of that vaccination is to expose you at a lower level so that when your body sees it for real, it attacks it more quickly and prevents you from having those bad outcomes.
