How many injections are given from rabies after a dog bite to a person? - briefly
After a dog bite, typically four to five doses of anti-rabies vaccine are administered for post-exposure prophylaxis against rabies. The first dose is given immediately, followed by three or four additional doses on days 3, 7, and 14.

The number of injections required for post-exposure prophylaxis (PEP) against rabies depends on several factors, including the type of vaccine used and the immunization schedule followed. Typically, two main vaccination regimens are employed: the Essen regimen and the Zagreb regimen.
The Essen regimen involves administering five doses of vaccine over a period of 21 days. The first dose is given immediately after exposure, with subsequent doses on days 3, 7, and 14, and the final dose on day 21. This regimen is widely used and has been shown to be effective in preventing rabies.
The Zagreb regimen, on the other hand, requires four doses of vaccine. The first dose is administered immediately after exposure, followed by doses on days 3, 7, and 28. This regimen has also demonstrated efficacy in preventing rabies infection.
In addition to these standard regimens, a single-dose vaccination protocol may be used in some cases where the vaccine is administered immediately after exposure, along with passive immunization using human rabies immunoglobulin (HRIG). This approach can be particularly useful when resources are limited or when compliance with the full vaccination series is uncertain.
It is crucial to note that the success of these regimens depends on prompt administration of the vaccine and, in some cases, HRIG. The sooner the treatment is initiated after exposure, the more effective it is likely to be. Furthermore, adherence to the complete vaccination schedule is essential for ensuring full protection against rabies.
In summary, the number of injections required for rabies PEP typically ranges from four to five doses, depending on the specific vaccination regimen employed. However, prompt initiation and strict adherence to the prescribed schedule are vital for achieving optimal results.
