Everyone’s first question after getting a COVID-19 vaccine is whether their body is producing antibodies that offer effective protection.
Most antibody tests that are currently available look at IgG and IgM. However, if you have recently encountered other viruses, your body will produce more of these and increase the level of antibodies in the blood, so such tests are unable to evaluate the efficacy of the COVID-19 vaccine in a targeted manner.
Carelink has already begun offering a Covid-19 Vaccine Neutralising Antibody Test. Anybody can be tested for neutralising antibodies using just 3ml of blood taken two weeks after receiving a second dose of vaccine.
Under normal circumstances, the immune system will begin producing antibodies after the virus infects the body. These antibodies are described as either binding antibodies or neutralising antibodies depending on how they interact with the virus. Binding antibodies bind to the virus, but cannot stop the virus infecting cells, while neutralising antibodies bind with the virus, identify the location of the cell, and reduce its ability to infect other cells. For this reason, neutralising antibodies are an indispensable part of the equation if you want to find out whether your COVID-19 vaccine is working.
