I'm not sure what to think about this preprint. It seems to be contrary to most of the other information I've seen about natural immunity vs immunity from vaccines. The only thing that is consistent is the conclusion that previous infection followed by vaccination provides additional protection.
Either way, if I was to be infected I'd much rather get infected after being vaccinated than with no vaccine.
>>>Conclusions: This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity. Individuals who were both previously infected with SARS-CoV-2 and given a single dose of the vaccine gained additional protection against the Delta variant.<<<
Background Reports of waning vaccine-induced immunity against COVID-19 have begun to surface. With that, the comparable long-term protection conferred by previous infection with SARS-CoV-2 remains unclear. Methods We conducted a retrospective observational study comparing three groups...
