"It is discriminatory to treat natural immunity differently to vaccine mediated immunity, and this is something that ethical, evidence-based public health policy should reflect. This argument implies that the UK government should allow care home workers and frontline healthcare staff with sufficient proof of natural immunity to continue working for as long as that immunity can reasonably be expected to endure. Such an exemption would prevent the unnecessary loss of valuable employees who do not pose an increased risk of transmitting coronavirus to vulnerable individuals." I would also like to see this equality reflected  in the self isolation policy. Where an individual with natural immunity is not forced to self isolate for 10 days after contact with a positive case.
