The irresponsible thing about healthy, low-risk people not taking vaccines is that it puts high risk individuals at higher risk of catching the virus because high risk people are the ones that can't take the vaccine.

Vaccines are not 100% effective but they don't have to be. The goal here is to reduce transmission in the population to a level where the virus can no longer spread. That is only possible if enough people take the vaccine and healthy people should absolutely be in the front of that line.

This is not a purely personal choice. You have to understand that by deciding not to immunize yourself you are making a decision for everyone else.
