Reminder: Over 60% of the Vaccinated ALREADY Had COVID

How do you calculate the ongoing efficacy of a vaccine against a disease you're already immune to?

By now the world (minus the ladies on The View) has come to accept that natural immunity provides VERY ROBUST protection against SARS-CoV-2 (the virus which causes COVID-19).

Be sure you visit our immunity cheatsheet from a month ago! We’ll update that shortly. And if you’re not a subscriber throw us a dime or two.

I emailed the CDC some time ago asking for information about the survey they conduct around vaccine hesitancy. I was asking about cross-tabs when low and behold they sent me to a special “COVIDVaxView Managers Page” which allowed me to drill into the survey in ways I can’t do with the raw table.

I had never laid eyes on that table before but there are ALL KINDS of things to drill into. Here’s the most important stat to look at right now.

62% of respondents self-reported that they were 1) fully-vaxxed and 2) had gone through Covid ALREADY!

Now there are some weird things in the data here but regardless — the question is — how do you calculate the effectiveness of ANYTHING when a majority of people getting the vax were likely ALREADY immune to it?

  • When they compare cases for “fully vaccinated” vs. “not fully vaccinated” are they taking this into account?

  • When they log hospitalizations are they asking previous immunity question?

  • When they denote “not fully vaccinated” why don’t we have a breakdown of 1 shot, 2 shot, 2 shot+14 days or previously infected?

Honestly, this is just the tip of the iceberg. More on this “hidden” tool later.
