Ignoring the higher risk of major long-term damage incurred by letting yourself get sick when you could've been vaccinated, I don't understand how this thought process accounts for anyone else.

What if my main reason for getting vaccinated is to lower my chance of infecting an immunocompromised person I care about? Even if I could somehow be 100% certain that if I were to be infected it'd be fully asymptomatic, the vaccine still helps me avoid spreading COVID-19 further.

Do you imagine young people who get flu shots do so only because they're worried about dying from influenza at 20?
