My body, my choice. I wouldn’t be able to sleep at night if I had the vaccine, knowing what I know about them. The regulators and doctors know that there’s no way to know the long term sides because they test for auto immune diseases and cancers for 3 years in animals prior to giving to humans. The vaccinated are the animals.
Nobody should argue that it is your choice what your put into your body including vaccines. I just don't get why you think you have special knowledge about these vaccines much of the rest of the world does not. You may know people who have had negative experiences that influence your thinking, but unless you are an expert in virology and pharmacology, I rather doubt you know more than the rest of us do.
One thing you are absolutely correct about is the speed at which these vaccines have been approved for use against COVID as compared to other medications for other ailments and diseases. No doubt there is a huge gamble involved. If people who have been vaccinated start dropping off like flies, the lawsuits will put these manufacturers out of business.
With everything in life there are trade offs. If someone is confident they are healthy enough to survive COVID and they fear the unknown long-term effects of the vaccine greatly then they will probably make the decision you have. It's all a matter of what you fear more. Of course other issue might contribute to one's decision about the vaccine. Such as, if you need to travel for work and travel is restricted for folks not vaccinated, then they would have to choose between their fears and their livelihood. Or if like me, half your family lives in a different country and either your country or theirs restricts travel based on being vaccinated, some like me would rather be able to visit family than worry about unknown side effects from vaccinations.
