The vaccine manufacturers have never claimed it to be 100% effective. If you compared the number of deaths from the vaccine or of the vaccinated to other medications including over the counter standards like aspirin, you'd see that there is no 100% cure for everything. Thousands of people die from taking aspirin every year. It's like seat belts, seat belts save lives but not every time, but you are far better off wearing one. But that's nuance, and we can't have nuance (or as some would spell it newontz).
