Yes. I did a test last year to check for antibodies generated through the vaccine and antibodies generated through an infection.
Vaccine was positive, infection negative.
“In participants that had COVID-19 and were tested one week after symptoms developed, antibody tests detected only 27% to 41% of infections. In week 2 after first symptoms, 64% to 79% of infections were detected, rising to 78% to 88% in week 3. Tests that specifically detected IgG or IgM antibodies were the most accurate and, when testing people from 21 days after first symptoms, they detected 93% of people with COVID-19. Tests gave false positive results for 1% of those without COVID-19.”
You might also want to check out https://wasp-lang.dev/ - it lets you use React & Node.js (although it seems you prefer php), but you don't have to write API endpoints + everything works out-of-the-box

Frontend frameworks like React are used everywhere. For real web applications like Facebook, they totally make sense. But for a lot of other projects, they don't because those projects do not have a complex UI/UX and so the framework adds more complexity than needed.
No, there is no missed rule, the comma is the only official decimal separator in these parts.
But I can relate to the the OP.
Us here in the comma world are forever converting numbers in CSV and Excel files back and forth so as to display them in a proper number format.
It’s like that darned USB port, you have to flip it 3 times to get it right.
Since it's a big "moat" for parts manufacturing (mainly for defense industry)... I predict the USA will give up imperial units when it's empire finally collapses.
Perhaps in the next few decades as China builds its own economic sphere.
I was about to comment that feet, yards and miles are not imperial measure; but I checked, and WP says they are in fact imperial units. So i learned something today.
We also use apostrophe as the thousands separator, so: 1'234'567.89 which I personally always found much more readable that using commas and dots. Is there any other country that uses this combination?
While OP here made a mistake, some countries use mixed systems depending on what it is used for . Switzerland for example uses comma for normal numbers and dot for currency alone.
The GDPR-compliant export tool they offer should also encode your albums, I don't think it will be easy to port them somewhere else, but it should be possible
I am now using my Flipper Zero for such things including entering passwords at our Dashboards.
