For rabies vaccination, those who choose the 4-dose regimen can receive only four doses. In addition to the 4-dose program, there is also a 5-dose vaccination program, and it is recommended to follow the vaccine regimen. Rabies vaccination prevents rabies, and due to the high mortality rate, it is recommended to get a rabies vaccination as soon as possible after being scratched or bitten by a dog or cat. The number of shots varies depending on the type of vaccine. There is the 4-dose rabies vaccine type, which is given as two shots together at the 1st vaccination, and then one shot each at the 1st and 2nd week. There is also the 5-dose rabies vaccine type, which is usually given as a single rabies shot on the day of injury, week 1, week 2, week 3, and week 4. Theoretically, 4 rabies vaccinations are about as effective as 5 rabies vaccinations because of the differences in manufacturers and dosages, which lead to differences in the way the shots are given.
