The ‘Covid Vaccines’ are not vaccines but bioweapons designed to cause injury and death, Dr. Death.
Once again, a vaccine contains a substance called an "antigen" which stimulates the immune system into producing antigen-specific T-cells, B-cells, and antibodies.
There is ample evidence that the Covid vaccines do this. Part of the process of analyzing clinical trial data is to measure the production of antigen-specific antibodies in trial volunteers.
Here is a study published in one of the top scientific journals, Nature, which examines specifically antibody production following Covid vaccination: Predictors of long-term neutralizing antibody titers following COVID-19 vaccination by three vaccine types: the BOOST study.
Do you have a valid scientific source for your claim that people receiving Covid vaccine do not have a subsequent specific immune response? And no, Mercola, Sherry Tenpenny, RFK Jr., McCullough, or any of the others who have pushed antivax propaganda are not scientific sources. For the most part, a legitimate source is either catalogued at www.pubmed.gov or at the CDC.
