Research led by scientists at Emory University in Atlanta found that while tetanus and influenza vaccines prompt the body to produce long-lived plasma cells that generate antibodies, COVID-19 vaccines do not.

They found that these participants had durable plasma cells—a type of cell that provides lifelong immunity—that generate antibodies to influenza and tetanus but no or few durable plasma cells working against COVID-19 spike proteins.
Frances Eun-Hyung Lee, professor of medicine and director of Emory University’s Asthma, Allergy, and Immunology program, told The Epoch Times that it is still unclear why COVID-19 vaccines do not confer durable antibody immunity, though there are several possibilities.
“They undergo changes in their RNA and changes in their DNA so that they can become resistant to apoptosis (cell death).” “There’re many other factors and mechanisms and programs, and we’re trying to study those and unravel those steps so that we can figure out how to make the SARS-CoV-2 mRNA vaccine better.” Having long-term immunity also does not “guarantee complete protection against future infections,” Dr.
Lee agreed, adding that while her study found that antibody protection is short-lived, there are other cells in the body, like T-cells, by which vaccinations confer long-lived immunity and could, therefore, still be helpful for people at a higher risk of infection.
The mRNA vaccines cause the body to produce short-lived plasma cells that can only generate antibodies for a period of time before dying off.
Boosting Did Not Increase Durable Antibodies Some study participants took several doses of COVID-19 mRNA vaccines during the study period.
Infections Did Not Enhance Immunity Some participants likely contracted COVID-19 throughout the study period, indicated by a sudden spike in COVID-19 antibody levels despite a lack of immunization.
