In nature, antibodies are produced after infection to the human body, however, a vaccination leads to the same effect. The standard RNA vaccine has a RNA molecule encoding the full lengh of the spike protein. After injection of the RNA vaccine, a human cell translates many spike proteins from the RNA molecule in the vaccine. Then, a human immune system starts to produce antibodies, which bind to the spike proteins. Most of the generated antibodies can prevent spikes to bind human receptors, and can protect us against the virus infection.
