Because you're not a rabid anti-vaxer? Or because you aren't someone who selfishly thinks that because they haven't had it, or have a God-given immunity to it, it's nothing to do with them?

Being an asymptomatic carrier may be the explanation as to why you've been exposed to it so many times. Stop acting like a second hand Trump - get jabbed, for the sake of everybody else, even if you don't care about yourself.
