Sorry for hijacking the thread again but the antibody saga unfortunately continues! From the previous episodes: very low number of antibodies in a private lab result (blood test, antibodies against S spike protein). A similar test at Semmelweis University was clearly positive. I'm in the same boat with the people with the Sinopharm vaccine (mine was AZ), who received similarly contradictory results. Semmelweis University and some doctors say one thing (in agreement with the FDA, that this result doesn't really matter), other doctors and most immunologists I hear say the opposite (and two of them even published a preprint paper a few days ago about the high number of negative Sinopharm results
https://www.medrxiv.org/content/10.1101/2021.07.15.21260362v1). As I said I'm pretty much in the same boat of not knowing who to believe as the ones who got Sinopharm, even if for different reasons. Confusing.
So: new tests, at the same private lab, but with testing the T-cell immunity too this time. Results: for the antibodies against the spike protein, it was almost the same: 34, so at the very bottom of the "moderate" range again, which was called practically negative by a doctor previously. The T-cell immunity: absolutely zero, nothing for two of the categories measured (relative IFNG+CD4 cells/million cells, activation of cytotoxic cells and relative CD40L+Cd4 cells/million cells, support of antibody production), and 57 for one category, where the minimum should be 500 (relative IFNG+CD8 cells/million cells, destruction of virus-infected cells). So I'm a total negative as far as T cells go.
The good news is that (probably due to the ongoing Sinopharm controversy) GPs are allowed to administer the 3rd round of vaccines from 1st August, but at least 4 months after the second shot (which is still more than 2 months for me), but in special cases the GPs can make their own decisions about the timeline (and which vaccines to give).
I have posted my results in a Facebook group where doctors (real doctors) answer people's questions about the vaccines. They seem to be very conservative about this, they are fully on the side of the FDA and Semmelweis University. They said they don't want to get into a scientific debate about this because they say I still may be protected but probably in my case it is better to try to get the third vaccine before the four months end, just to be sure.
So this is my plan now. If I'm really unprotected, then I'm really lucky that the Sinopharm controversy happened at the same time and that may help me to the third vaccine quickly. (And my GP is usually quite cool about these things, he has been giving me the flu vaccine free of charge for years now.)
