If there was evidence, that "is thought to" would've been replaced with "is proven to".

"At day 119, the binding and neutralizing GMTs exceeded the median GMTs in a panel of 41 controls who were convalescing from Covid-19, with a median of 34 days since diagnosis (range, 23 to 54)." There's also data showing much higher neutralization titers against variants in those vaccinated vs. those naturally infected. Of course, this is only one measure of immune response. Many other things are more difficult to measure, so we don't know too much about e.g. T cell responses from natural infection vs. vaccination. So it's hardly proven but there is some highly suggestive evidence.
