A timeline of how long vaccine boosters take to build immunity, according to experts

“Detectable antibodies peak around two to three months after full immunization, and then begin to wane thereafter,” explains Shruti Gohil, M.D., University of California Irvine Health’s associate director of epidemiology and infection prevention as well a professor at the UCI School of Medicine. … “Boosting should result in antibody production within days of the booster vaccine, but peak levels still occur around the two-week mark, similar to initial vaccines,” she tells Good Housekeeping.
