There are other reasons but I thought I would present this one from the NIH first.
You can read the study at the link below. -CA

In this sample, 1493 people (24.3%) thought they had had COVID-19 but only 245 (4.0%) reported having received a positive test result. Reported test results were often incongruent with participantsí belief that they had had COVID-19. People who believed that they had had COVID-19 were: more likely to agree that they had some immunity to COVID-19; less likely to report adhering to lockdown measures; less worried about COVID-19; and less likely to know that cough and high temperature / fever are two of the most common symptoms of COVID-19.

At the time of data collection, the percentage of people in the UK who thought they had already had COVID-19 was about twice the estimated infection rate. Those who believed they had had COVID-19 were more likely to report leaving home. This may contribute to transmission of the virus. Clear communications to this growing group are needed to explain why protective measures continue to be important and to encourage sustained adherence.

    I thought the question had to do with whether or not a bonafide COVID-19 infection gives the person the level of immunity a vaccine does.

    This is why I said Iíve been searching for reliable sources regarding natural immunity vs vaccine immunity and found many conflicting opinions although the majority seem to feel that the natural immunity from having had Covid is less reliable than the immunity from the vaccine

    My doctor friends tell me that natural immunity is a shorter term and more variable prevention from COVID than the vaccine. I recently mentioned a case a doctor friend told about in which the person had COVID earlier this Summer and died with second bout of COVID. See link.

    For the sake argument, let us assume the anti-vaxxers' self-reported cases of COVID are all bona fide and that natural immunity protects against contracting and spreading COVID for a full year. Will these anti-vaxxers in year's time be amenable to being vaccinated? I doubt it.

    By the way, I discussed the issue of natural immunity with my doctor friend this weekend. He confirmed that not all cases of Covid are equal. A light case of Covid provides light immunity. To get the sort of immunity that a vaccination or two provides, you need to survive a hospitalized case of Covid.

    I remember listening to podcast last year in which a doctor was speculating that it would probably be possible to catch Covid-19 more than once, but that each follow-up illness would be less severe than the previous one.

    Your example of a person having a mild case earlier this year then dying from a more severe case this summer would probably contradict that thesis. Unless... the first case was one variant, and the second case was Delta.

    I don't mean to quibble over details, but I raise this as a reminder -- the virus can mute again, and future variants could cause more severe illness than the others.

    The best way to keep the virus from mutating is to create herd immunity -- as quickly as possible, worldwide. And I would think it's faster and more effective to do that through vaccination.
