All a vaccine needs to do is show the immune system a (hopefully useful) antigen. Your immune system doesn’t know or Big face coffee owner shirt really how that antigen got there, just that it wants to kill it right now. That’s what’s being referred to as “receptors of the virus’ own spike protein”. That’s receptors on cells that mediate the immune system response and decide if it needs to murder itFor COVID, the spike protein is the antigen of choice. Pfizer and Moderna use mRNA suspended lipid so your cells will take it in and manufacture that spike protein to trigger your immune system. The Johnson & Johnson vaccine uses a modified adenovirus that’s been rendered incapable of replication and just makes your cells produce those spike proteins. In this it’s a protein subunit vaccine, and they seem to have modified yeast to produce the spike protein which they tend extract to produce the vaccine.iirc this is the same kind of vaccine (or very similar_ as is used for Hep B. So it may have the same downside as that, where you need 3-4 doses for long term immunity.Im going off a tangent here regarding the statement “science tends to follow the money”. DO NOT take this as anti-vax rhetoricYes it is true but this is also how we get shit “science” popularized like the ones about food/nutrition sponsored by companies like coca cola. Or the ones about fossil fuels and plastic waste by the oil industry. Cherry picked research that promotes the sponsors’ brand and products.I just wish we stop hanging everything on the money, and by extension, to where it is accumulated (hint: corporations). But yeah, i know most people would defend them because it’s all they have ever known in their lives and that it is blasphemy to think about another perspectiveThis confused me as well. I didn’t think vaccines were supposed to bind to viruses. I thought they were supposed to trigger an immune response which would then attack the virus at a much later date, when the host is infected. At that time i’m assuming the vaccine itself would no longer be in the body to interact with the virus.

Cuban refugees are an excuse. They’re deep republicans and dems going anti socialist will do little Big face coffee owner shirt most of them. Democrats, much like republicans, are staunch capitalists, mind you being liberal literally means supporting capitalism. The Biden admin just released a paper saying those against global capitalism are considered domestic terrorists. America still dismantles socialist/communist countries. Leaving these countries to thrive are a direct threat to the success of capitalismMy take on it has been that the staunch anti-socialist powers in the US are afraid that if the embargo is lifted, Cuba might actually do well. Considering, they‘ve managed to somehow (more or less) been able to stay afloat for 30 years since Soviet financial support has dried up and, all things considered, are actually doing better economically than most comparable states in that region, that isn‘t completely out of the question.Granted, chances are that the whole regime unravels quickly because the US as a common enemy is what‘s holding the place together.
