It doesn't sound great tbh mate, I feel for you. Never knew it could cause deafness although like I said, it's not a condition I know much about.
I suppose your answer though explains why I don't think there's a need to criminalise or sack somebody for not getting the vaccine. There's still a lot of things we don't know about it and the proposed dosage regimen for the AZ vaccine hasn't even been trialled on over 55s as far as I know.
I honestly think there'll be a struggle to get over 70% of the population vaccinated for it because I think a lot of the younger generation, with next-to-no risk of suffering from Covid, will view the risk of getting a relatively unknown vaccine greater than getting Covid. Hopefully though, if there's a big uptake of the vaccine (and it's safe) from most other age groups, that should shield people who would like to get vaccinated but can't for medical reasons.
