Given there are some organizations that are forcing you to get a vaccination. 1 in a million chance of dying from something you were forced to do is different than 1 in a million chance of a pseudo-random event. Makes no sense to continue with J&J given the other two don't have this issue at the moment.
Of course, the utilitarian approach is to simply continue vaccinating with J&J since surely more people are helped than harmed. I'm sure they'll reverse this decision soon enough.
