  “Experts not involved with the study said the VA population does not reflect the general population.”

    Indeed, but this can be seen as a signal for the wider population for further investigation - certainly we'd now like to prove the negative.

    That isn’t going to change the core basic facts of how the immune system responds or slowly wears away upon repeat infections.
    • anonuser123456 4y ago
      I’m not sure what basic facts you are talking about. The VA population is a lot older and sicker than the general population and will contain a large number of immunodeficient individuals. Further, the population of multiply-reinfected and symptomatic people is biased towards the immunodeficient since immunocompetent people tend not to get symptomatically reinfected. Extrapolating the general case from these populations makes zero sense.
