Not a fan of mandatory vaccines in general (more on that below), but especially this particular one at this time. I think the better way is very robust public education to try to get people to take them. Yes, I understand that people won't get vaccinated if it's not mandatory, and I admit my views may be a little idealistic/pie in the sky.
There is something a little off putting about the concept of being forced to have a needle stuck in the arm and possibly having side effects like chills, fever, fatigue, etc. even though it's more of a temporary nuisance than anything. There is nothing else quite like that in life. You are required to have car insurance in most places, but they don't stick it in your body (well, some may argue they stick you in a certain part of the body )
