Massachusetts Mandates Flu Vaccine

In the midst of coronavirus panic, the Massachusetts legislature passed in the veil of night, and without notice or opportunity for public comment, that all students age 6 months (daycare) - 30 must have a flu vaccine. I hear Arizonan’s complain that our legislators haven’t returned to session since the shutdown. But I’m now wondering if it’s a good thing. If they were in session, would we be permitted at the capital to oppose any such legislation?
