If bitten by a dog, how many rabies shots are given to a person? - briefly
If bitten by a dog, the standard course of treatment for rabies involves five doses of the vaccine. The initial dose is administered immediately after the bite, followed by four additional doses on days 3, 7, and 14.

If a person is bitten by a dog and there is a risk of rabies exposure, it is crucial to seek immediate medical attention. The number of rabies shots, also known as post-exposure prophylaxis (PEP), required depends on several factors including the vaccination status of the dog, the severity of the bite, and the overall health condition of the person bitten.
In most cases, a standard regimen consists of four doses of rabies vaccine administered over a period of 14 days. The first dose is typically given as soon as possible after the exposure, ideally within 24 hours. This initial dose serves to jump-start the immune system's response to the potential infection. Subsequent doses are then administered on days 3, 7, and 14.
However, if the person has previously been vaccinated against rabies or is in a region where rabies is not endemic, a different regimen may be followed. For pre-vaccinated individuals, two doses of vaccine are usually sufficient—one dose on day 0 and another on day 3 or 7. This approach leverages the existing immunity from previous vaccinations to provide rapid protection.
In addition to the rabies vaccine, medical professionals may also administer human rabies immune globulin (HRIG) for individuals who have not been previously vaccinated. HRIG is typically given at the time of the first vaccine dose and provides immediate passive antibodies to fight off the virus until the person's own immune system can produce enough antibodies through vaccination.
It is essential to complete the entire course of rabies shots as prescribed by a healthcare provider, even if symptoms do not appear. Skipping doses or not completing the full series can leave the individual vulnerable to the potentially fatal disease.
In summary, the number of rabies shots required after a dog bite depends on various factors but generally ranges from two to four doses over a period of 14 days. Immediate medical intervention and adherence to the prescribed vaccination schedule are critical for effective prevention of rabies.
