A lie is a lie, obi wan....it is not more deadly to an individual. You aren't 10,000 people, you are one person. More people have died with COVID across all age groups, that is not the same thing as COVID being more deadly than polio to a person of any age group. How many more people caught COVID and had nothing happen?
If you got the first shot, you had a few months to benefit from it. The second shot, same thing. Now each booster buys you about ten weeks. Each time is a gamble that the effects of the shot are less than the effects of getting the virus, over the time that you are protected. Right now, if you were to get a first round J&J shot, it would be essentially pointless on its own. In twelve weeks, even if you have five shots right now, you will be behind the virus. This is why we have never vaccinated against a coronavirus.
