Just to point out there isn't 'a good chance' ... statistically there's 'a small chance'.
In any medical procedure we have to evaluate the risk/benefits, and when dealing with populations, yes, the greater good wins every time.
There is every chance that the govts over-react to pandemics, but if they waited until people were dying faster than the bodies could be cleared away, then it would be a different story and those who choose not to immunise would find themselves pariah in their own communities.
There is every indication that western governments were all too slow to react, because of underlying libertarian political principles (as was the case in the UK), and so the early death rates were higher then they need have been. In the UK's case there was an exercise which highlighted shortcomings in the case of a pandemic, but of course nothing was done.
Asian and Far Eastern countries generally fare better because they have a stronger social conscience, so they mask up as a matter of good manners whenever they're ill, whereas we in the west bleat on about 'civil liberties' because we're generally under the misguided assumption that the state is there for my benefit and is out of order when it acts in ways contrary to my perceived benefit.

There will invariably always be the risk of side-effects, known and unknown. The job is to ensure Big Pharma is not 'getting away with murder', literally as well as figuratively. While people might be naive in trusting 'the authorities', the tendency for 'conspiracy theories' to emerge in regard to almost any contentious scenario, actually does more harm than good, as the germ of truth tends to get swamped in an outpouring of nonsense ... and 'empty vessels make the most noise'.
