A new study reveals that the human body’s immune response to COVID-19 may vary significantly depending on the presence of pre-existing antibodies from prior infections or vaccinations. Researchers found that individuals with pre-existing immunity exhibited stronger and more rapid antibody production after exposure to the virus, suggesting potential differences in how the immune system reacts in vaccinated versus unvaccinated populations. The findings could have implications for understanding long-term immunity and the effectiveness of booster doses. The study also highlights the role of memory B cells in sustaining antibody levels over time, offering insights into why some people experience waning protection.
