The recommended time to get a rabies vaccination after a dog bite is within 24 hours. However, it is not that the recommendation is to race to get the first shot as soon as possible within 24 hours. Rather, 24 hours is enough for most people to get their first rabies vaccination at the nearest vaccination station. After the first rabies vaccine is administered, and regularly thereafter, the corresponding rabies neutralizing antibodies will be produced 1-2 weeks after the first shot is administered. If the injection is given 2-3 days late, it is likely to be able to exert a rabies preventive effect as well. If there is an increased likelihood of rabies, which mainly refers to a bite that has reached the level of tertiary exposure, rabies serum or immunoglobulin will also be administered. Because it takes time for the rabies virus to enter the peripheral nerves from the wound site, if rabies immunoglobulin or serum is administered locally to the wound site within 24 hours, it is likely to prevent the spread of the rabies virus to the peripheral nerves at the end. Therefore, it is still recommended that rabies vaccination be administered within one day, and rabies serum or immunoglobulin be administered if necessary.
