AFAIK, you can actually test blood reactivity to virus protein, proving a positive.
I'm not sure how you would prove that a person actually got vaccinated and it wasn't the case of doctor pouring vaccine down the drain, someone else taking the vaccine instead etc.
I don't have time to explain to you the intricacies of antibody testing. However, it is much more difficult than to standardize on what antigens and what titres to pick and how to correlate that for a "positive" result. Testing for neutralizing antibodies is even harder, because it involves isolating the antibodies and testing them against live virus particles and a cell culture.
And yes, standardizing such testing, as complicated and expensive as it is, across all the relevant labs across the country would be a bureaucratic nightmare.
I'm not going to engage with your bullshit about doctors faking vaccinations.
Iceland accepts either vaccine or previous infection certificates[1][2]. They seemed to handle covid well, being fairly strict.
Fake vaccinations[3], including fake certificates are popular, especially when they are forced. If you want a fake vaccination, I know a guy who knows a guy. Point is - it's not bullshit.
Yes, checking certificates is easier than testing for antibodies. While harder, I still think antibody tests would have less false positives and I most certainly don't think the relative easiness to administer vaccines is a good reason to require everyone to take them, even when they are more immune then those who only got the vaccine.
A friend had an antibody test as he already had covid and didn't want to go for a vaccine. It was no big deal.
Did you notice that Iceland is a slightly smaller country, with probably quite a bit fewer medical labs? Also an island, with islands generally having an easier time with all the pandemic restrictions stuff?
I don't even know how Iceland's health system is organized. But it would be a good bet that it is light years ahead of the mess of the 52 states plus territories and whatever! Much different story.
