How do you know the vax did not kill Betty White?
Because she's 99 and most that are 99 could die from natural causes or age-related problems literally at any time.
Assuming it was the vaccine with no evidence whatsoever isn't rational. It diminishes every other opinion express. It's too bad you're not grasping that. The average person thinks you're nuts.
You're supposed to be a Christian. You're consumed with paranoia and fear. And, that doesn't come from God. Check your Bible.
