I’m in CA, so I’m not familiar with that site in particular, but the similar tracker sites here also say there are tons of appointments available, but once you actually try to sign up there’s nothing available. I’d be surprised if 10% of those “available” vaccines are actually available.

I've helped a number of people get appointments in MA and had zero issues securing probably a half-dozen appts for people in the last 10 days. If the trackers are showing say >3-5 appts then there are usually some actually available (the macovidvaccine site is scraping/updating quite frequently).

Also, because of the way the MA state reservation system works -- they give you 25 minutes to fill out the appointment details once you "claim" a slot, often times you'll find a decent number of timed-out appointments showing up after the fact. Not to mention there are plenty cancellations (as presumably people are booking for family or maybe just vaccine shopping).
