Coronavirus
In England we are still wearing masks and there is still talk of people having to have Covid_19 passports to show that they have been vaccinated to enter some venues.
As far as mask wearing, I think that most people are accepting it but if it becomes like wearing a seat belt it would be a problem. That is because many people find it hard doing things while wearing a mask. Personally, I have tripped over a couple of times, got knocked down by a bike once, and knocked over items on shelves because I can't see what I am doing. That is because the mask steams up my glasses. I even sometimes stop wearing my glasses in shops because it becomes so hard to see.
Also, we don't know how much protection masks provide really. They only protect others rather than the wearer and it is not as if there have been scientific studies to show that masks have stopped transmission of the virus. It probably only stops the spread of germs if people cough.
As far as enforcing vaccines, I think it is starting to happen. If people are forced to show proof that they have been vaccinated to do many activities, I think that this would be going too far, and would restrict civil liberties. On the other hand, if loads of people choose to not be vaccinated there is no end to the spread of the virus, so it will go on indefinitely. Another problem is that even people who have been vaccinated can still get the virus, but it definitely does offer some hope.
So, generally, I would argue that mask wearing may be useful for stopping some transmission but it should not be enforced in the same way as seatbelts. Also, it will help if most people have vaccines but I am not sure that it can be enforced through people being only allowed to enter public places through proof of having been vaccinated.
On the other hand, we will probably get to the point where people can't get jobs in health care without agreeing to being vaccinated and, perhaps, that may be acceptable because it is to protect the public. This may be acceptable as a way of risk minimization in the same way as it being necessary to agree to police clearance in order to work with vulnerable people.
