Having SARS-CoV-2 once confers much greater immunity than a vaccine—but vaccination remains vital

Source: Science.

One of the more distressing consequences of the push for universal Covid-19 vaccination is the emergence of in-group/out-group thinking. The vaccinated became the cool people (in-group) and the unvaccinated became the uncool people (out-group). This is distressing because witch hunts, systemic prejudice and totalitarianism all begin with similar thought processes.

The instant report may help defuse the social psychology a bit by showing that the vaccinated can cause the same social problems as the unvaccinated:

The new analysis relies on the database of Maccabi Healthcare Services, which enrolls about 2.5 million Israelis. The study, led by Tal Patalon and Sivan Gazit at KSM, the system’s research and innovation arm, found in two analyses that people who were vaccinated in January and February were, in June, July, and the first half of August, six to 13 times more likely to get infected than unvaccinated people who were previously infected with the coronavirus. In one analysis, comparing more than 32,000 people in the health system, the risk of developing symptomatic COVID-19 was 27 times higher among the vaccinated, and the risk of hospitalization eight times higher.

This headline finding comes with significant caveats. Note, for example, that the comparison at hand is between vaccinated immunity and infected immunity, not between vaccination and the absence of vaccination. The finding is that natural immunity appears to be more robust than vaccinated immunity.

This result should change the Covid-19 narrative (and public policy) in significant ways. Simplistic in-group/out-group thinking no longer applies because the efficacy of natural immunity changes the categories. Where once we had vaccinated/unvaccinated groups, now we must account for:

  • Naturally immune/vaccinated
  • Naturally immune/unvaccinated
  • Not-naturally immune/vaccinated
  • Not-naturally immune/unvaccinated

  1. Nor unexpected, as we know that the vaccine does to produce IgA antibodies and infection does. IgG saves you but IgA helps shut the door.

    There may also be a difference between those infected and then vaccinated and those vaccinated who get a breakthrough infection.


  2. In-group/Out-group logic and systemic prejudicial consequences. I see this very concept actively deployed in the cancel culture crowd. Attempts to suppress or punish any cultural observation or comment no matter how playful or innocent is immediately scorned with sensationalism and claims of “racial or cultural insensitivity” unless of course observations or comments originate from the cancel culture crowd. Gee, I wonder who they consider the out-crowd.


  3. Israel was Pfizer only. Moderna? And immunity from an infection fades. So, lemme see… it’s been 18 months since my infection. I need a booster. Hang around the local ER? Or, get a vaccine? Tough choice.

  4. Speaking of “in/out” groups, where do these folks fit in the arc of insanity.

    “The mobile vaccination event that was shut down was set to take place in north Georgia, where a group of protestors showed up to harass public health professionals, according to the Journal-Constitution.”


    I guess it is tit for tat. Mandating a vaccine followed by street justice vigilantism to shut down a vaccination site.

    Whatever happened to the “my body, my choice” chants of the anti-vax group. So now it is “your body, my choice”.

    Of course, this is Georgia, the state that sends Greene to be their representative, so it kind of fits, I suppose.

  5. I’m sure this makes Len happy but the biggest problem I see is government placing responsibility for enforcement on business owners. I think we all know government attempting to enforce it’s mandates would result in a civil war so it chickens out and makes others responsible at their own expense.


    1. I have no problem letting businesses decide. What I do have a problem with is the government trying to stop businesses from doing what they consider best for them.
      Or telling localities they cannot take steps to control the pandemic as they see changing situations.

      Without naming names, FL comes to mind.
