This. It gets old seeing people post that getting the vaccination if you're under (insert age here) isn't necessary. I get tired of saying if you are a younger asymptomatic carrier and you infect my 80 year-old-grandmother who dies as a result, that it's the equivalent of involuntary manslaughter. Before anyone gets up in arms because I'm spewing hyperbole, If you cause a death due to negligence (a carnival ride malfunction due to lack of inspections, texting while driving, etc.), you are guilty.
In other words, if you don't do it for yourself, do it for others. It's just sad that so many people have no compassion for others.
