This will be coming to all western countries, just in a different manner. It will be "voluntary", but you will need it to go on planes, go to the movies, and even go to the supermarket to get food.
You will need it to live.
Since there is still not enough supply of the vaccines right now, most of the government and employer messaging is that the "vaccine" is voluntary. But they have already hinted that when they get enough supply, it could become a "Voluntold" situation. It's voluntary, but you can't go grocery shopping, or to work, or to the park, or on a plane, train, or bus. You can't go and get your driver's licence renewed either.
So at this point is the vaccine really "Voluntary"? No, it's not.
Watch for this later this year. Along with new "Varients" which will require more restrictions and control of your freedoms.
