Also, the mRNA vaccines are "replicas of the spike protein".

"your body reads that mRNA and uses its natural machinery to produce a specific protein that would naturally be on the virus that you are vaccinating against — in this case, the spike protein"

The two authorized mRNA vaccines instruct your cells to reproduce a protein that is part of the SARS-CoV-2 coronavirus, which helps your body recognize and fight the virus, if it comes along. The COVID-19 vaccine does not contain the SARS-Co-2 virus, so you cannot get COVID-19 from the vaccine. The protein that helps your immune system recognize and fight the virus does not cause infection of any sort.

The cell would then turn this mRNA into a viral protein. A single viral protein would not be enough to cause the cell harm or the host to become sick. Given the right mRNA and the right protein, however, it may activate the immune response. In this case, the immune system could begin mounting a response and deploying antibodies against the virus without being infected.
