How does one determine and or prove immunity to Covid?
My question also. Where do you got to get tested for prior infection antibodies? Wife is looking at losing her job and I may follow soon after.
The same way Covid is proven...
Can’t be too safe with something that is 99.9% survivable.
This whole thing is BONKERS.
Antibody testing. If you have already had Covid (whether you knew it or not) you have natural antibodies. His suit argued that he should not have to take the jab, since he already had natural antibodies.
Probably either from antibody tests, or, in other countries, because they keep records of those who were infected and recovered. Not sure how you’d prove it here in the USA or get that onto some kind of “passport” here due to HIPPA and lack of coordination and systems integration.
Our leaders’ saying that those recovered need a vaccine are little bit silly but I suspect that they don’t want to send mixed or nuanced signals so they just want to create one mandate for all.
Due to the spike of Delta in Israel - which is a highly vaccinated country - they re-started their vaccine passport system for public gatherings. However, they recognize “previous infection and recovered” as equal to a vaccine. If you are recovered you get the passport regardless of vaccine status. There are probably more than double the official covid numbers of people who were infected and recovered. Nobody knows for sure especially those who were asymptomatic but the Red Cross tested donated blood and found 20% of it contained antibodies. If that is representative of the population (it may not be since many blood donors are front line workers, police, EMT etc) then the number of people infected in the USA is twice that of the official stats... pushing us closer to herd immunity.
In Oregon, you have to get a Dr.’s prescription to get a test and receive a card. Then you have to wave it in front of your woke democrat employer with a hint of legal action.
That is the experience of someone I know.
I donated a pint of blood at the Red Cross a month after recovering. They sent me back a notice through the app that I was positive for antibodies. Free process.
There probably is some elaborate test to determine amount of anti-bodies present.
But, why are a minority of Americans scared of this nothing burger covid vaccine? Common sense is lacking is what I conclude. Just think, nearing 200,000,000 Americans are on schedule to be jabbed in just a few weeks. Hospitals are required to report any adverse effects from vaccine to VAERS. Recent count of adverse effects (Death or Serious hospitalization) is running at 0.006% of those jabbed. To be scared of something proven safe by 99.994% borders on some psychotic illness.
I had it before it even had a name, and I have the IgG and IgM antibodies to prove it.

I believe they can test for the Anti-Bodies.
The way I see it. If you are still alive, then you are good.
Viruses mutate over time to a weaker form and burn out.
All the “variants” is still Covid 19 from different countries. For instance, the “delta” variant is Covid 19 from India. The “lambda” variant is from Peru.
We give it the geek alphabet names (which should be offensive to Greeks), vs. naming the country of origin. There is no way Covid 19 is still around at this point. Viruses are seasonal.
They will never stop unless people do not comply and push back legally and lawfully. It’s been about 19 months since 2 weeks to stop the spread. See how the game works?
Think about it this way. Did a the same flue virus from a year and half ago stick around before Covid.
Answer: No it dies in the Spring and Summer time.
We have had 2 Springs and 2 Summers and there are still playing the same Covid 19 fear card by calling all these variants. It’s nonsense.
