How many vaccinations are needed after a dog bite? - briefly
After a dog bite, the number of required vaccinations typically depends on the immunization status of both the dog and the person bitten. If the dog's vaccination history is unknown or incomplete, post-exposure prophylaxis (PEP) may be necessary, which usually involves a series of rabies shots over a period of 14 days.

How many vaccinations are needed after a dog bite?
When an individual is bitten by a dog, prompt medical attention is crucial to prevent potential infections and diseases. The primary concern following a dog bite is the risk of rabies, a viral disease that affects the nervous system and is almost always fatal once symptoms appear. Additionally, other bacterial infections can occur, such as those caused by Pasteurella multocida, Streptococcus, or Staphylococcus bacteria.
To mitigate these risks, a series of vaccinations may be necessary. The exact number and type of vaccinations required depend on several factors, including the severity of the bite, the health status of the victim, and whether the dog is known to be vaccinated against rabies or not.
Rabies Vaccination
If the dog that caused the bite is unknown or unvaccinated, a post-exposure prophylaxis (PEP) regimen for rabies is recommended. This typically involves a series of four vaccinations administered over a period of 14 days:
- Day 0: The first dose of the rabies vaccine is given immediately after the bite, along with human rabies immunoglobulin (HRIG) if available. HRIG provides immediate protection against rabies while the body develops antibodies from the vaccine.
- Day 3: The second dose of the vaccine is administered.
- Day 7: The third dose is given on this day.
- Day 14: The final, fourth dose completes the series.
Tetanus Vaccination
In addition to rabies vaccinations, a tetanus shot may also be recommended, especially if the individual's last tetanus booster was more than five years ago. Tetanus is caused by Clostridium tetani bacteria and can lead to severe muscle spasms and lockjaw.
Antibiotics
While not a vaccination per se, antibiotics are often prescribed to prevent bacterial infections that can occur from dog bites. Commonly used antibiotics include amoxicillin-clavulanate or doxycycline, depending on the specific bacteria involved and local resistance patterns.
Monitoring and Follow-ups
It is important for individuals who have received vaccinations after a dog bite to complete the full course of treatment as prescribed by their healthcare provider. Regular follow-ups may be necessary to monitor for any signs of infection or adverse reactions to the vaccines.
In summary, the number of vaccinations needed after a dog bite can vary but typically includes a series of four rabies vaccinations over 14 days. Additionally, a tetanus shot and antibiotics may be prescribed based on individual needs and local medical guidelines. Prompt and comprehensive treatment is essential to prevent serious complications from dog bites.
