Difference between antibodies made after infection and antibodies made after vaccination?

When someone is infected by Covid-19 what part(s) of the virus does their immune system make antibodies against? I’m aware that the mRNA vaccine will be translated into the spike protein so that our immune system will make antibodies against that. I’m assuming that when getting infected by the virus our bodies make antibodies against numerous parts of the virus. But considering antibodies only protect people for a few months, it probably targets parts of the virus that mutate very often and the amount of spike protein antibodies made are too few to offer lasting protection?

Disclamer: Don’t quote me on this one.

It’s been shown that the most effective antibodies that neutralize the SARS-CoV-2 virus are antibodies that bind against the s-protein on the surface of teh virus, which is the protein that the virus SARS-CoV-2 uses to infect our cells. For the most part, it seems that people infected with the virus will make antibodies that will recognize the s-protein on the surface of SARS-CoV-2. Now, the virus does have other surface proteins that our immune cells could recognize and form antibodies against as well, so there is the chance that your immune system could make antibodies against sars-cov-2 that do not necessarily bind against the s-protein. 

The vaccine will induce your cells to produce and present the s-proteins, allowing your immune system to respond to it and make antibodies against the SARS-CoV-2 s-protein.
