People have serious side affects from getting Tattoos every year. For example you can catch hepatitis from getting a Tattoo.
Yet look around you, and you will see lots of people with Tattoos.
My point being that the medical risks of getting a Tattoo is far greater than getting a Covid Shot.
If you are willing to risk your health for vanity's sake, maybe you would be willing to take a smaller risk to save your own life???
