NORTHERN IRELAND,might find itself in a position where uk health workers leave to work in Rep of Ireland Or Wales or Scotland which have not adopted this rule.

Although it might result in a reduction in the number of health workers I agree (in principle) that health workers should be vaccinated.
At the moment Covid is more likely to lead to hospitalisation, and possibly death, for the unvaccinated. I doubt that health workers would be unaffected by this, meaning that their possibility of death if they catch Covid is greater than for vaccinated health workers. This would also reduce the health service work force, but would increase the possibility of having passed on the disease to colleagues and patients.

We hear a lot of campaigners saying that this infringes their rights, and they should be allowed to make their own choice. Fine, but that choice is whether to work in the health service, or to avoid having the vaccine. Except for those with medical exemptions there is no reason to have unvaccinated people working in the front-line health service.
