He learned from his mistakes. Look at the kooky liberal states that still force COVID vaxxes at their state colleges like PA, NY, Mich, VT, mass, Md. Like it still start of the pandemic.
CT no longer requires the jab, at least at Community or State Colleges, however UConn is somehow separate and I believe still requires it.
As you said Mass still has a jab mandate for colleges, but not a booster. However, if you don’t have the booster and are near someone with the Coof, and test negative for the Coof, you are still forced to quarantine for 5 days, but if you are boosted and don’t feel sick no test needed just pretend it didn’t happen.
