It is usually okay to be a day late for the second dose of rabies vaccine. The rabies vaccine protects against rabies, and individuals who have been bitten or scratched by an animal suspected of having rabies should more often than not be immunized with this preventive vaccine. If the rabies vaccine is administered after an exposure, there are two immunization programs to choose from, one requiring five doses and the other requiring three, both of which have the same immunization effect. And individuals who are a day late for the second dose can continue to be immunized as normal. According to the rabies vaccine vaccination guidelines, if for some reason one’s injection is delayed, subsequent injections can be postponed according to the original schedule and do not need to be revaccinated. Individuals who need rabies vaccination should go to the CDC or a hospital and get vaccinated on time. If you experience any discomfort after vaccination, please visit the hospital in time to avoid delays.
