Yes, that’s called pathogenic priming. It was the exact reason no SARS or MERS vaccines were brought to production.

I read it but I don’t understand it. My reading makes me think it is saying is that we might be training the bod to overreact when they get the virus. So a mutation to the SARS-Cov-2 might invoke a over reaction by the immune system of the vaccinated?
Am I reading that correctly or have 180 degrees backwards ?
Or is it saying that the protein the vaccine targets can cause a bad autoimmune response because vaccine might teach the immune system to attack a normal part of the body aka normal protein.
