NJ website draws a distinction between third dose and booster, with third dose needed for the immune-compromised, but a potential booster being for the genera public. I haven’t followed too closely, but is it likely the booster would at a different strength than the 3rd dose? If that’s the case, then “jumping the line” might not be a good idea.
I’m Moderna, so I’m definitely going to wait to see what is said about their need. Unfortunately, the local hospital where I got Moderna last January is now exclusively Pfizer, so I’ll have to track down a Moderna site when my time comes.
