Parent however qualified that they were considering the risk to themselves and their own contacts, who are also vaccinated. For them and their associates, treating this like the flu seems more reasonable. Assuming they’re in the USA, everyone who is unvaccinated at this point (except children, who have low risk of death) is doing so by choice. We can’t be expected to put our lives on hold for conspiracy theorists forever.
But my point wasn't about op, it was about the population as a whole, hence the "especially in vulnerable population" part.
