Goodluck.
To my knowledge, trials on these types of vaccines have ever been performed on animals and failed miserably. I'm sure Astra Zenica and others have been able to tweek things a bit in their experiments on Uyghurs, as Pfizer did in Africa, still, I can't help but think you're being a guinea pig. Thousands of health professionals have refused the vaccine in Europe, but if you want to roll the dice it's your choice.

Vaccines create the conditions to cause your body to create antibodies for that particular bug - but! Your body may not create a lot, or do it slowly, or may even not work because the vaccine is "dead" and your body recognizes it as such, which are all why vaccines tend to be somewhere between 20 and 80% effective. The idea that a vaccine is 95% effective is VERY unusual.

So, once your body has antibodies, the infection can still get in, it is just that your body doesn't have to go through all the motions of creating a correct antibody - the vaccine helps speed up the process. But it still takes time for the body to ramp up production which can happen slower than the virus spread. And that process can still allow for symptoms to arise.

Clinical trails have 4 phases, there hasn't been enough time since it's discovery to complete one phase successfully. Clinical trials normally take 6-7 years.
I agree the language is misguiding, but so is the plague of false positives being touted as fact, even after the inventor of the PCR test stated back in May that it would give false positives at the rate of 88-92%.
I would be more worried that the producers have been offered immunity from prosecution, if there are any dire irreversible side effects. ( Here in the UK at least ).
