My aunt was an antivaxxer. She died of covid in 2022. To your point, I guess she can't regret not getting it. To regret something a person has to be alive to begin with.

Because they're dead, you dolt, I lost my sister to covid19, it was an unspeakable horrible death. She was vehemently against the vaccine, until she cried when she was taken off the respirator, with the understanding she was about to die! Please stop being stupid!😥
