“If indeed a feature of Coronavirus Vaccines is a hypersensitivity to future Coronaviruses”

What is the relationship between a vaccine developed in 2012 and one developed in 2020?

The new vaccines may, or may not mimic the behavior of a 2012 vaccine.

And this virus may, or may not mimic the behavior or the virus tested then.

Fair enough. Assuming that immunology is a feature (which it may or may not), it would explain why we are being prepped for a yearly coronavirus booster

The operative word is “may”.

Nobody knows and I am not willing to take that risk.

And this virus may, or may not mimic the behavior or the virus tested then.

Sounds like something you'd want to know before a mass "vaccination" program.
