I’m not saying that I love catching Covid because I can’t help but ignore public health guidance - it’s because I’ll be the only one to catch it out of a group of people every. Damn. Time.
I’m also not trying to get people sick, I work entirely remote and really only see friends and family - but won’t go anywhere socially if I’m sick with anything.
At the end of the day, you could live in an antiviral bubble filled with bleach but some random person could cough or touch something they interacted with and make your grandparents sick.
All you and your grandparents can really do is take precautions, and enjoy your loved ones.
Also, I’d say your comment is pretty disingenuous and condescending, it assumes the only way to not kill your grandparents is by getting vaccinated.
Unless they live in a vault, they’re gonna be exposed to everything life can throw at them. If you’re healthy, but still worried about being asymptotic you can take Covid tests, or if you’re their only caretaker you can wrap yourself up hazmat style, it’s not like everyone working at a hospital died to Covid exposure, or made 100% of everyone they interacted with sick.
I’m definitely pro vaccine, but it’s not some magic security blanket - It’s a risk mitigation tool at best
