Cell therapies are hard to get through FDA approval and expensive to develop. With mRNA side stepping the gene therapy safety testing, the flood gates have been opened. All big pharma is chasing this full speed for everything.
The does makes the poison. I've worked around a chemist who had a hook for a hand. She blew her hand off with sodium azide powder. I'd never want to be around a bottle with 50 g of it in powder. However, a bit of azide to keep microbial growth down in a 1 mL solution is not a big deal. But yes, caution is cheap and there is no reason to take the risk. Use PPE.
These sodium azide worries seem way overblown. I used to use it daily working in a research lab to keep microbial growth out of the samples. Sodium azide powder is a bad chemical but 20 mg/kg is eating ~1.6 grams for a 175 dude to kill half of the dudes. The solution is likely < 0.1% sodium azide. Nothing to worry about. This is not the issue to worry about.
Great question. You are correct in one instance, but it isn't surprising that this works in the other places.
antibody based tests like LFT, Rapid antigen tests, and all other tests that are like this pregnancy pee test us lab made antibodies stuck to a cotton strip to feel for the virus particles and (with some biochemistry 'magic') turn pink if they find the target. Many or most of these tests use a pool of antibodies to look for multiple different parts of the virus. This is similar to how natural immunity uses many different antibodies each looking for a different part of the virus. So if one tiny part of the virus changes natural immunity still works.
The 'vaccines' produce just 1 small part of the virus (the spike protein). Most of this protein is useless for antibodies to become sensitive to but other parts will work great for antibodies to stick to. Once these few small parts of the larger spike protein mutate (change slightly), the antibodies generated by the vaccines will no longer work against this new variant of covid-19 (Covid-21K to be more specific).
Antibody and the rapid tests that use antibodies physically feel for unique pasterns on the target object. A metaphorical example would be the tread pattern on a car's tires are very unique, but if you are only able to look are a tire tread pattern as a way to identify a car and the next model year of the car has different tires, you won't be able to identify the car anymore (i.e. vaccine failure). However, the stitching on the seats, and the texture of volume knob, weld on the trunk hinge all still feel the same in the new model year as the old model year so you can still identify the car (antibody based tests like lateral flow tests). [The tiny size of these features is ~proportional.]
PCR works by looking for two specific ~30 base pair sequences (A T C & G) that are a specific distance apart. The covid test looks for 3 of these pairs. Omicron only has 2 of these pairs. So, one of the pairs changed enough to no longer work like you speculated.
Great question.
Additional interesting things...
Table #1 shows the % positive test rate is 1.1% with many testing setting being below 0.5% positive. What is the false positive rate for these lateral flow tests?
Figure #13 shows that for cases there was very little difference between vaccine free & vaccinated even before Omicron. This would kill the vaccine mandate usefulness argument.
Figure #15 shows an interesting peak in the boosted when boosters just started. They presumably have some really interesting data that we'd like to see.

Funny how they are starting off with 3 injections for the pure bloods in the trial. That gives them a 6 week window before the are "vaccinated". What % of the total test time will they be in the strange 6 week window.
Now put this together with the leaked mouse data that showed this shit targets the ovaries. If this happened to an egg cell that becomes a person, that person would have that modified genome in every cell of their body including half their eggs or sperm cells. Or that person would just die in utero.
