At the end of the day it comes down to personal responsibility and if certain people still choose not to accept it there's little more the government can do.
Let me draw a parallel example: A lot of people resisted a seat belt law because it should be "personal responsibility" or an infringement on their "freedoms" etc.
In 1982, the year before the seat belt law was introduced, 2,443 people were killed in accidents on Britain’s roads. 30 years later, that figure had dropped to 816. Now that might not all have been due to seatbelts, but they were certainly contributory to it and yet people's "freedoms" are still intact.
Not wearing a seatbelt only affects you, but someone who is (for whatever reason) not vaccinated, can spread the virus to others and may even have a variant that the vaccine may not work on.
Now, yes, their decision not to be vaccinated may *also* be selfish, but demanding that the rules be changed because of what the majority have done (let alone because someone has declared an arbitrary date as "Freedom Day") when there is still a risk of new outbreaks, as is happening at the moment, will just make the situation worse, so decisions that affect the whole population have to consider this fact.
There will ALWAYS be a risk of new outbreaks, this is one virus that is not going away for a very long time. But surely being on a small island like ours, and with the undoubtedly fantastic vaccine programme that we had the privilege to be a part of, does it not make total sense to want to "keep it at bay" as much as possible?
When you have the bulk of people doing their thing to try and get a grip on the virus, why should a minority spoil it for everyone by leaving themselves totally open for infection and further spreading, as is about to happen again by the sounds of things?
The vaccines work, it's a proven fact now. They're not perfect by any means, i recently heard a mate of mines dad has tested Positive and he'd had both of his jabs, so a few will slip through the net, but in the same breath he's not "very ill" at all, it was just a random test with an unexpected result, but then again we always knew they weren't touted as 100% effective.
Our main downfall will generally come from people bringing the virus in from outside of the UK, seeing as some countries are still in a right state and out of control and it's no surprise that people want to run away from these areas, but if you're going to reside here then i think it's only fair that you get vaccinated.
