The immune system can take a few days to produce antibodies against any given invader. Evidence suggests most people who catch SARS--2 have an antibody response between 10 and 14 days after being infected. Antibodies are detected in some patients a long time after symptoms have passed, and not at all in a small number of cases in the timescales of those studies, according to the review.that cause common colds, people have been known to be reinfected after just 80 days.
