It's a long post I'll try reply.Agreed. Each case is different and people should be allowed to take advice and make a risk judgment call.
I can understand boosters every few months if you can't afford to take a few days off as risk of infection is apparently somewhat reduced. However you are likely adding other risks too.
In your case everyone else on the whole planet might have to vaccines every 3 months to reduce risks to minimum so you might not have to take boosters to avoid infection.
Its not reasonable to expect everyone to take boosters every few months to avoid isolation while the background antibodies get to 99% or whatever.
Lastly it should not be critical to have a vaccine whether you have antibodies or not in order to maintain a livelihood especially when so many are already protected against severe outcomes.
We are literally a few percent away from having 90% antibodies and protection against severe outcomes but some people are saying force everyone to vaccinate or take their jobs, houses, cars, lives....its insane.
As is forcing everyone to have vaccine passports to travel which will probably mean bi-annual boosters.
I hope as the antibody levels rise the general panic, knee jerk reactions, insane virtue signalling and vaccine zealotry subsides.
Right now to me the vaccine zealots are slightly more insane and damaging than the 5g anti-vaxxers as they are willing to give up everyone's freedoms for absolutely nothing.
Once those freedoms are gone its going to be much harder to get them back...ask google about your right to privacy for example.
The problem we have with Covid is no prior immunity to SARS CoV2. Once we have been fully vaccinated or infected we will have prior immunity and the potential for serious illness is not zero but quite low. I mentioned coronavirus OC43, there is evidence emerging that it caused a similar epidemic when it emerged around 1890. We all have been infected by it initially in childhood, then occasionally repeatedly in adulthood causing the common cold.
So I repeat I am not advocating repeated booster except for a small subset of people for whom it will be advantageous.
All that is required is people have prior immunity, then when you get your booster infection you will not develop a viral pneumonia, rather just a snotty nose.
You asked in your original question if vaccine passports are supported. Yes in the manner imposed in Europe, where vaccination, prior infection or within 48hrs of a negative test are equally accepted.
I know you have put a lot of faith in discovery numbers of infected at 80% I hope you are correct, but have you looked at how they arrived at that number and what faith discovery has in that number. My understanding is it was one of a number of scenarios in a scenario planning meeting but was jumped upon by the press.
Doing a quick calculation of my close family and friends I would put infection at no more than 50% What is your number.
