I'll try to respond to your post with something a little more positive. Have you noted any side effects? If not, depending upon when and where you received your dose, and whether you were a "one and done" or got boosters as well, can all change the probabilities for you.

When they were first rolled out for the general public early in 2021, there were a large number of saline doses. I have it on pretty good authority that quite a few of these saline doses, in the beginning, were sent to Walgreens. (The inventory was low, the logistics were just getting up to speed, and Walgreens didn't want to appear like they were behind the curve for potential customers.) Also, the Jannsen doses were quite a bit different from Pfizer, Astra-Zeneca, and Moderna. If you received a Jannsen dose, even if it was "potent," you didn't receive mRNA.

Unfortunately, for those who opted to receive boosters after the initial dose, that places those patients on the probability wheel for a harmful dose.

If you don't already know about this site, you can research whether the dose you received was part of a bad batch: http://howbad.info/
