In the only study so far [81], which dealt with the chemokine responses following an entirely inactivated Covaxin COVID-19 vaccine administration, manufactured in India, it was clearly demonstrated that there was an elevated induction of CCL4, CXCL1, CXCL2, and CX3CL1chemokines, a fact that indicates the activation of innate immune cells. The gene discussed is CCL4; the disease is COVID-19.
