> while a previous infection will cause your body to produce antibodies for a much larger set of targets on the virus, which in practice leads to a more robust immunity.

That is simply not a statement you can make without supporting evidence.

Your immune systems binds to irrelevant targets all the time. People normally got measles once, but lots of people got it multiple times.

It is entirely possible that your immune system will bind to something that mutates rapidly and have worse response than the vaccine.

As someone who got the Covid19 in Original Flavor(tm), I still went and got the vaccine. I don't want to be one of the unlucky ones whose immune system didn't flag the spike protein for destruction.
