If the rabies vaccine is used for pre-exposure prophylaxis, it is mostly limited to people in high-risk occupations, and regular antibody checks are required before judging whether or not to administer the vaccine; for post-exposure prophylaxis, the vaccine is administered on days 0, 3, 7, 14, and 28, with one intramuscular injection each, and is usually effective within 24 hours. If the four-dose method is used, one dose each is given on days 0, 3, and 7, and one dose is given on any of days 14-28 for a total of four doses. Under normal circumstances, rabies vaccine is only used for post-exposure prophylaxis. If scratched or bitten by cats, dogs and other animals, the vaccination is administered according to a course of treatment to stimulate the body to produce specific antibodies to neutralize the virus. The production of rabies antibodies is approximately 100% 45 days after the first vaccination, and rabies can be prevented with five doses of regular vaccination. During the rabies vaccination period, it is important to prohibit smoking, alcohol, tea and spicy and irritating foods, and to drink plenty of water and rest. If a dog or cat scratches or bites you again within six months after receiving the rabies vaccine, you usually do not need to receive the vaccination again, but if you have been vaccinated for more than six months, you should receive five more doses.
