Moreover, regarding how long does rabies vaccine work in humans, it can give protection for 7 to 10 days before the induced antibodies are formed. See also Figure S1 . They are formed when the body’s immune system comes into contact with a ‘foreign’ substance, for example bacteria, viruses, a vaccination or, during pregnancy or transfusion, a different HPA. The adaptive, or acquired, immune response takes days or even weeks to become established—much longer than the innate response; however, adaptive immunity is more specific to an invading pathogen. The Red Cross says donors will receive news about their antibody status about seven to 10 days after they donate. So please know that 3-4 days of symptoms after the vaccine is nothing.
