I think you need to step outside your bubble actually and get in the real world.
Postcode lottery for Cancer treatment has been going on for decades, I had to go to a panel to be approved for the treatment that I receive, fundraising takes place left, right and centre for treatments to take place abroad for some that are not approved in the UK.
Why would I not be able to get treatment I need by not having a vaccine?
Not one member of the public went and had a flu jab to protect me for the last few years did they, nor would I expect them to. Except my husband who had to PAY for it, because do you know what I was told when I enquired about it? Well you are protected because you have had the flu jab
Stop worrying so much if you have had the vaccine. I'm not worried about getting an illness and dying so don't you worry on my behalf.
