Is a booster needed for no COVID-19 antibodies post-vaccination?
CHARLOTTE, N.C.  Sandy, a WCNC Charlotte viewer, recently reached out with a vaccination dilemma. Sandy's mother got her COVID-19 shots, but continues to test negative for coronavirus antibodies. Sandy wanted to know whether a booster shot is needed. First, a reminder, that not every antibody test will accurately show if the vaccine worked. Dr. Brannon Traxler, Public Health Director for South Carolina's Department of Health and Environmental Control, said a negative antibody result is not always a reason to panic. "Most of these tests look for whether you have antibodies from a previous infection, not necessarily the same ones that might have been made by the vaccine," Traxler said.

In fact, the experts say this is why they do not recommend antibody testing after vaccination. "When people don't make antibodies, it doesn't mean they don't have any protection, but they may have less protection than we may have hoped for from vaccination," Priest said. "We don't have any guidance on timing a booster, how do we mix products or not mix products. So, our guidance is: if you have issues with your immune system and you think you might not respond to the vaccine, you still need to be very careful to avoid COVID." While doctors do not know what other steps can be taken to boost a person's immune response, researchers are working to find the answer. "There are studies going on right now to look at whether there's value in getting a third vaccine dose, but we just don't have the results from those studies," Traxler said.
