Covid is very often asymptomatic but still spreads. There is no way you can know that you haven't had it again, haven't spread it to others, and won't continue to do so without a vaccine.
And while it may be asymptomatic for you, you can still spread it to others who it will be very symptomatic for - including others who have been diligent and have taken the vaccine. You can kill people without knowing it.
The longer people go unvaccinated, the more likely mutations are to catch on, which may defeat the vaccine.
You are placing your general dislike of "putting things into my body" above all of our safety and welfare, and you are interfering with our collective efforts to end this pandemic and move on for the sake of our health and economy.
Please don't be so selfish.
