This is interesting. I have worsening allergies to certain nuts, as in each time I am exposed (inadvertantly I assure you) I feel more ill. Originally it was simply vomiting, then it became severe vomiting and nausea and the last time my blood pressure dropped so low I was only able to see in monochrome - my colour vision had disappeared completely. I had to remain prone for over an hour. When the manager of the residential home where I work mentioned it to the Home GP (who incidentally is also my own GP) she said that I would be exempt from having the vaccination. Hopefully this will continue to hold true. I wonder if having parents who both had pulmonary emboli and had to be hospitalised would also help my case.
It certainly won't hurt to try and wriggle out of the vaccine going down the official route rather than just stubborn refusal. I intend to push for a written guarantee that I won't experience health issues that will prevent me from working at my current level of productivity. My sick pay won't even cover my rent, let alone other expenses so I cannot be off sick for more than a week. The government has indemnified vaccine producers so I'm going to push for them to take responsibility in writing for any decline in my health for as long as I have symptoms, and for covering my salary for however long it's needed.
Apart from that, there are studies showing this vaccine increases susceptibility to other viruses. See this example. Given that I haven't had even one day off sick in 3 years, and only 2 in the past 5 years, I want a written guarantee I won't be ill more often after the jab. If I am, I want both full salary reimbursement and compensation, adjusted for inflation if it's longer term.
It's a far shot but last time I tried that approach I got a mask exemption letter from my GP so it's not like I have no reason to suspect it may work. I was polite and I made sure I sounded apologetic, concerned and stressed, but willing to go ahead with whatever they suggest provided that I have that guarantee in writing. Worked like a charm.
