Which methods can be used to evaluate a person’s level of immunity or protection from COVID-19? How do I know if my 2nd (or 3rd) dose worked? Are there any ongoing trials (for immunity tests)?

Any biological effects the vaccines have are essentially irrelevant, they're a tribal sign and "sacrifice ritual".
So there's no point in worrying about it.
