I was born with active chickenpox, I contracted TB as a 4 year old, and spent 9 months on an isolation ward in Germany. I had no visitors during that time due to it being in lockdown and there being no proper treatment during the TB epidemic after WWII ended, I have come into close contact with active carriers of TB since but had natural immunity, I still cannot donate blood as result, I have had all 3 MMR diseases naturally, and bouts of flu of various strains including Asian Flu, I have been in contact with malaria, dengue fever, typhus, and paratyphoid when I lived in Africa but had been vaccinated before I went, so was safe, I have had the smallpox vaccination. The only vaccines I had in my early years were Polio (there was an epidemic in UK when I was at school, but we all missed it, Also Pertussis vaccination although I did suffer Croup as a baby. So I am familiar with vaccinations, and the need for them. This SARS one is no different in my view, so I will take it when offered next year,
