There are two ways you can look at this. What I expect is people will mock and call citizens and lawmakers ignorant, and call for some tougher mechanism to make sure people get vaccinated.

The other is that when you push too hard, you get pushback, you catch more flies with honey than vinegar, etc. We are seeing this in other areas too, where pushing too hard on a liberal democratic (for lack of a better term) agenda leads to populist revolt, and effectively swings the pendulum way back past where most agree it reasonably should be. Until recently, it would only have been an extreme fringe group that was against long standing childhood vaccines. But it's not a surprise that when you start pushing people to do something, they start to become more wary and reject things that they previously would have accepted at face value. There is a pathway to authoritarianism where resistant is met by more and harsher rules, and one to a more enlightened society where people are treated like adults and mostly make the right choice.
