Behind the Science
The production of antibodies works a little differently when dealing with a vaccine and not a natural infection. When individuals take the COVID-19 vaccine, the antibodies produced after being administered with the vaccine (such as the Pfizer vaccine) are the S and RBD, not the N.
Antibodies are what indicate your immune system is responding and working to protect your body from an antigen – a substance that is not recognised by the body. For example, if an individual contracts the coronavirus for the first time and/or has not been vaccinated, this virus will not be recognised by the body as yet. Along with antibodies, T and B cells will be produced. T and B cells may sometimes enable immunity of an individual, particularly the B cell as they can become memory cells.
However, antibody levels do decrease as time goes on therefore even if you have been vaccinated or have had COVID-19 in the past, boosters are still recommended to ensure you have an adequate number of antibodies in your system. It is similar to getting a flu vaccination during flu season each year.
Our COVID-19 Antibody Immunity Test can measure your antibody immunity profile letting you know the best time to get your booster.
