Perhaps British people have not had to do this, but there are polio and meningitis vaccinations required for citizens of many developing countries, and TB tests required to enter the UK
I'm from a country with a very high rate of TB however I entered the UK without any requirement for checks. Many countries do lung screens rather than asking for vaccine proof (that was required when I got residency in a Middle Eastern country) for the simple reason that the BCG vaccine does not provide anything like sterilising immunity from contracting TB.
I do think some people are being very harsh here, by suggesting that the OP risk anaphalaxys and death, or basically shrugging and saying tough shit your choice. I can completely understand why OP turned up at the vaccination centre - there's this awful desperation at present between fear of catastrophic health consequences vs fear of catastrophic life consequences that makes those of us in that position feel utterly desperate.
It's not as simple as saying if your GP says you're officially exempt then fine otherwise it's just you making a choice and you need to suffer the conseqeunces. Medics aren't gods and people, especially with chronic health conditions, often know their own health and bodies best. Just think of how many threads there have been on here of people being completely dismissed and giving appalling medical treatment, for everything from thyroid issues, to childbirth injuries, to being sent home from A&E seriously unwell. You often have to advocate very hard for yourself and to get taken seriously.
And it's utterly mad that someone like the OP, who has had covid and has no reason to be seriously concerned about it, and who has previously had life-threatening adverse side effects from vaccinations, should even be considered as suitable to receive this vaccination. Because if it wasn't this highly politicised vaccine, no medic in their right minds would even suggest never mind attempt to insist on a medical intervention with that poor a risk benefit profile. It would be utterly poor practice, and unethical.
It is a truly horrible time for those of us in this position. I have genuinely sometimes thought oh well at least if I'm dead I won't have to worry about this any more.
Several of the people in my support group, who did chose to get the vaccine, have suffered relapses of their condition and I cannot go through that again. I just can't. And it is hurtful that there are a lot of people that, should my gp and consultant not agree with me (and there might well be tremendous managerial/political pressure not to grant exemptions), would be quite happy to see me, the OP and others like us live diminished, excluded lives on top of what we have already suffered.
I cannot face more months of neurological issues, pain, seizures, tendon breakages. My hasband cannot face more months of not being able to go to work and support us as he then has to care for me. I cannot lose the little life, as dimished as it is from the one I enjoyed previously, that I have worked so hard to build for myself after my old life was blown apart four years ago. Because when that happens, the gp is nowhere. Random people and their opinions online are nowhere.Most friends are nowhere. It's just DH and I in hell and alone.
I might never see my family again because of this. I never asked for any of this.
@MrsFelicianoLopez sorry about the derail. I think unfortunately unless people have lived it, they are generally not going to understand. It just feels so fucking unfair, we go through hell though no fault of our own and now this.
