Antibodies and Immunity

Recent studies reveal that while most patients develop antibodies after recovering from the coronavirus, a significant portion may not produce them at all. However, the immune system is complex, and other components, like killer T cells, play a crucial role in fighting off reinfections. It's suggested that the presence of low antibody levels doesn't necessarily indicate a long-term problem, as the body can ramp up its defenses upon re-exposure to the virus.
