We have a proposal in the UK that vaccine passports should be created. This seems to be under serious consideration by our government. The passports will certify that a person has received a Covid vaccination, or that he/she has developed natural immunity, or has recovered from a recent Covid infection. Some virologists are of the opinion that as many as 95% of the population have innate immunity to the whole family of Corona viruses. If this is born out by the passport testing, will it lead to a realisation that vaccinations are not required for protection against the virus?
