The validity of rabies vaccine is calculated from the day of the last injection, and the effective protection period is generally 6 months.
The rabies vaccine is only effective for 6 months, during this period, if you are licked, scratched or bitten by a dog or cat again, you do not need to be vaccinated again. After six months of rabies vaccination and less than one year, two booster shots are needed to obtain sufficient antibody protection. After more than one year, the rabies vaccine needs to be revaccinated.
Therefore, rabies vaccine is not a lifelong vaccine. After 6 months of rabies vaccination, if you have been licked, scratched or bitten by a dog or cat, you need to go to an immunization station as soon as possible to receive rabies vaccine, in addition to cleaning and disinfecting the wound immediately.
In addition, rabies is an incurable disease, the death rate is close to 100%, so this disease is prevention-oriented, once the rabies exposure, must be timely vaccinated against rabies.
