AHHHHROOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!! Vaccines could still protect against Omicron via powerful 'T cells' that are hard to measure but prevent severe illness and death https://www.businessinsider.com/omicron-vaccines-t-cells-despite-low-antibody-response-2021-12
AHHHROOOOOOOOOOOOOOOOOOOOOOOOOO!!!! Beyond the spike: Are T cell COVID-19 vaccines the future? https://news.trust.org/item/20211229201635-aif52/
By and large, antibodies are produced by activated B lymphocytes (a.k.a. humoral response) whereas T lymphocytes are responsible for the "cellular" response. Both responses are part of the immune system, but they act in different ways and even though I'm not familiar with the details of the articles mentioned, what is being asserted is perfectly possible. So your assumption is wrong. It is perfectly possible to have T Cell response with low or not measurable levels of Antibodies. Now, I'm not saying that this is the case with COVID or COVID vaccines, because, as I said, I'm not familiar with the details of the studies and articles quoted. I'm not an immunologist, but I am a physician and what I just wrote is pretty basic.
That's for those vaccinated who still have some viable T-cells left. Several researchers have reported "vaccines harm our immune systems"... mostly in regard to T-cells (some of them) either being destroyed or losing function... and negative effects appear to be cumulative. That is, the more shots/boosters, the greater the cumulative harm.
Sorry, but this is wrong. Even though there is an interaction between B and T Cell response, T Cells do not necessarily need antibodies to be activated.
Yes, that could be too. There has always been evidence and argument that the lifetime allotment of t-cells (and for antibody memory cells as well) is somewhat limited or can deplete so you have to be careful about triggering them with vaccinations unless the vaccination protection lasts for decades or so to justify the drawdown. Lots of arguments to be made about T-cells. I just don't buy into the idea that T-cells and their role cannot be talked about in the light of day here just because one forum member has a hissy fit. It can all be talked about.
[CITATION NEEDED} I posted a whole bunch of material for over a year from proper medical journals and sources explaining in detail how B and T-cell responses and antibodies interact and operate in regards to viruses. Have you suddenly discovered some new science? Are you going to parrot jem - claiming that T-cells would magically protect you against Covid even if you had no anti-bodies. It was all part of the anti-vaxxer "natural immunity" nonsense that these magical T-cells would show up and therefore we were close to "herd immunity". Scientists and fact checks have already refuted this nonsense in great detail. Explain to us why why they use anti-body tests (and not T-cell tests) to determine if you are protected against Covid (the same with other diseases such as measles, mumps, etc.).
AHHHROOOOOOOOOOOOO!!!!!! If antibodies fail, T cells in Covid-recovered people could shield from Omicron, says US study https://theprint.in/health/if-antib...red-people-from-omicron-says-us-study/780860/
"Yet to be peer-reviewed, the study has been conducted by US National Institute of Allergy and Infectious Diseases and Johns Hopkins University. It had a sample size of 30." LOL -- similar to a study in South Africa which had a sample size of 15 which studies if catching Omicron blocks Delta -- the sample size is so small that the results are not really meaningful from a broader perspective. Plus it is interesting to note the actual study shows that all 30 individuals had detectable antibody levels. All 30 individuals were previously infected. Proof of previous infection was established via anti-body tests.
