I volunteered for a fascinating COVID-19 study sponsored by Serimmune, a company in Southern California that is working on some low-cost antibody tests. The study is free, and every six months they’ll send you a home blood-testing kit and a few weeks later give you the results.

Here’s my first sample:

Oddly, despite being fully-vaxxed and boosted, I apparently have antibodies to only one of the proteins on the virus. Update from second test in Jun 2022: no changes, exact same results as last time.

Does this make me more susceptible to a real-life exposure?

I compared myself to an unvaccinated friend who unfortunately succumbed to the virus recently. Thankfully now fully-recovered, here are those test results for comparison:

As you can see, this person’s immune system appears way more knowledgeable about the various COVID-related proteins. Compared to those results, am I more vulnerable now to future variants than if I had been naturally infected?
