That's not what I was saying. If you are dead you don't have any long term concerns. People in high risk categories (the elderly and disabled) shouldn't use (likely rare) long term side effects as an excuse to remain unvaccinated when they are much more likely to die in the short term from covid. But hey, if they don't want to get vaccinated more power to them, society will be better off without them. Less money given out in state pensions and disability pay checks. Are they seeing record numbers of serious illness and death? The US is an excellent example of how these covid vaccines work. We have a very large pocket of idiots that have refused vaccines based on party lies...err I mean lines. You don't have to go to small countries or city states to try to find data, the US has all the demographics, population densities and varying vaccination rates. The vaccines prevent people from getting seriously ill and dying. We know this. That is not up for debate. What is in question is how long this protection lasts. Boosters are nothing new. The anthrax vaccine doesn't stop you from getting anthrax. It increases your chance of surviving the infection. Yearly boosters are required to maintain immunity. While the vaccine is not a common one it is an example of one that needs boosters and doesn't really prevent infection. Also: Hepatitis A Hepatitis B Haemophilus influenzae type B (Hib) Measles-mumps-rubella (MMR) Tetanus, diphtheria, and pertussis (Tdap) Varicella Shingles Pneumonia Varicella MMR All may require boosters at some point in a person's life.
