So sorry to hear about your sister. I watched this presentation and I am mad as hell. My first statement when they brought out this Coronavirus was 'It's a bio weapon'. I hope these people get put under the prison. We have six prisons in my county and they wouldn't like any one of those facilities! I visited all of them when I was selected to serve on the County Grand Jury (served 3 terms). N

That idea had flashed thru my mind, some kind of antidote to the vax. It has the job of wiping out the vax, not interfering with the evidence that you have actually been vaxed, and not as naive as a sponge pad up your sleeve.
Likely there would be some risk but balanced by reducing the risk of the vax.

I'd prefer a counter vax, but something like a flesh color stick-on may suffice. How long is the needle?

Vaccine-passport, papers? Solved.
The bad news is how to explain in 5 years why you are still alive! I'll take that problem when it comes.

Some way of twiddling the computer data may be better but I like the counter-vax as it could help those who have changed their minds.

I have a lot of sympathy with anti-vaxers but I am not one of them, I have had many vaccinations, for this virus I would go along when the animal trials and other trials and long term data is released and all the usual requirements are met. Even if my doc quotes the data I need to have some comfort that the numbers apply to my demographic and condition.
