The length of coronavirus immunity after being infected can vary greatly from person to person, a new study suggests. Researchers found that some individuals who had neutralizing antibodies against COVID-19 antibodies saw levels wane after just a few days or even a few weeks. But at least one-third of participants had no changes in levels after at least six months and some even saw levels rise, suggesting their immunity could last for decades. The data was then used to help create an algorithm to predict the trajectories of neutralizing antibodies over time. This implies that individuals may still be protected if they have a strong T cell response, despite low levels of neutralizing antibodies.
