Mice who received more than four Covid vaccine jabs had a collapse in their ability to fight the coronavirus, Chinese researchers have found.
The damage extended past antibodies, the immune system’s front line of defense against viruses and bacteria, to the T-cells that form the crucial backup.
The researchers reported the finding in a peer-reviewed paper published December 22 in the journal iScience. In surprisingly clear language, they warned:
Our findings demonstrate potential risks with the continuous use of SARS-CoV-2 vaccine boosters, providing immediate implications [emphasis added] for the global COVID-19 vaccination enhancement strategies.
Later in the paper, the researchers were even more direct:
We found that the protective effects from the humoral immunity and cellular immunity established by the conventional immunization were both profoundly impaired during the extended vaccination course.
