The point about J&J is that it is being billed as a one and done vaccine, which it practically isn't. So assuming that you can convince people to take the J&J, because it is only one shot, but then turn around and say, BTW to get full protection, you need to take a second one in 2 months, you are doing a bait-and-switch. The problem is that hold-outs aren't likely paying attention to this change, and will feel tricked and less trusting if they are told this after their initial shot.We want them to fully vaccinate with 2 shots. They don't want any shots at all. I am willing to compromise at 1 shot if it gets the deal done.
1 shot should still keep most of them out of our hospitals.
Sure one shot of anything is better than nothing, but given the lower effectiveness, you'll see some get covid and then blame the vaccine.
