>>Findings In this cross-sectional analysis of 26 823 adults from the population-based French CONSTANCES cohort during the COVID-19 pandemic, self-reported COVID-19 infection was associated with most persistent physical symptoms, whereas laboratory-confirmed COVID-19 infection was associated only with anosmia. Those associations were independent from self-rated health or depressive symptoms.

There are a lot of people who report they had covid but never had it confirmed via PCR test or serology. This is a problem because data from this group purportedly about covid, such as "long covid" symptoms or the robustness of natural immunity, is seriously compromised. You can see that idea here in this study and also in the difference between natural immunity studies which use self-reported data (which may indicate weak, declining or no protection), compared to studies which use PCR or serological confirmation. The studies in the latter group unanimously confirm the robustness and longevity of natural immunity.

  I can't believe natural immunity was ever in doubt. Is there a single disease for which natural immunity is not superior to acquired (via vaccine) immunity? I can't find one.

    You're not supposed to ask those types of questions - you're not a scientist. Leave the health mandates and questions to the scientists that we trust to lead us through the pandemic.

      I really hope this is sarcasm.

        I took it as such.

    I don't know if it has been studied much, but it stands to reason that a vaccine might impart superior immunity, especially considering variants and the fact that the vaccine is given in separate doses spread out long enough to induce more memory.
