How Many Rabies Shots Do You Need If Bitten?
If you’ve been bitten by an animal suspected of carrying rabies, the number of shots you need depends on whether you’ve been previously vaccinated. Most people who have never been vaccinated for rabies require one dose of rabies immunoglobulin (RIG) and a series of four rabies vaccinations, administered over a 14-day period.
Understanding Rabies: A Deadly Threat
Rabies is a viral disease that attacks the central nervous system, ultimately leading to death if left untreated. It’s primarily transmitted through the saliva of infected animals, typically via a bite or scratch. The virus travels through the nerves to the brain, causing inflammation and neurological damage. While rabies is preventable with prompt treatment, it’s crucial to understand the risks and act quickly if exposed.
The Post-Exposure Prophylaxis (PEP) Regimen
Post-exposure prophylaxis (PEP) is the recommended treatment after a potential rabies exposure. This consists of two key components:
- Rabies Immunoglobulin (RIG): RIG provides immediate, passive immunity by injecting antibodies directly into the wound site and surrounding tissues. This helps neutralize the virus before it can reach the brain.
- Rabies Vaccine: The rabies vaccine stimulates the body to produce its own antibodies against the rabies virus, providing long-term protection. This is administered as a series of intramuscular injections.
Who Needs Rabies Shots?
If you’ve been bitten or scratched by an animal, particularly a wild animal or an unvaccinated domestic animal, it’s crucial to seek medical attention immediately. Your healthcare provider will assess the risk of rabies exposure and determine if PEP is necessary. Factors considered include:
- The type of animal involved (e.g., bat, raccoon, fox, skunk, dog, cat).
- Whether the animal was provoked or unprovoked.
- The severity and location of the wound.
- The vaccination status of the animal (if known).
The Treatment Schedule: How Many Rabies Shots Do You Need?
The treatment schedule depends on your vaccination history:
Individuals Never Previously Vaccinated for Rabies:
- Rabies Immunoglobulin (RIG): A single dose, administered as soon as possible after exposure. The full dose is infiltrated around the wound, if anatomically feasible. If not, the remaining volume should be injected intramuscularly at a site distant from vaccine administration.
- Rabies Vaccine: A series of four intramuscular injections, typically given on days 0, 3, 7, and 14. Day 0 refers to the day you receive the first dose.
Individuals Previously Vaccinated for Rabies (Pre-exposure Prophylaxis or Previous PEP):
- Rabies Immunoglobulin (RIG): Not necessary. Previous vaccination provides immunological memory.
- Rabies Vaccine: A series of two intramuscular injections, given on days 0 and 3.
| Treatment | Never Vaccinated | Previously Vaccinated |
|---|---|---|
| Rabies Immunoglobulin (RIG) | Single Dose | Not Required |
| Rabies Vaccine Series | 4 Doses | 2 Doses |

Common Misconceptions About Rabies Treatment
- Myth: Rabies is only a problem in developing countries.
- Fact: Rabies exists worldwide, including in developed countries like the United States. While human rabies cases are rare in the US, animal rabies is still a concern.
- Myth: You only need rabies shots if you’re bitten by a dog.
- Fact: Rabies can be transmitted by various animals, including bats, raccoons, foxes, and skunks. Any mammal can potentially carry rabies.
- Myth: Rabies treatment is extremely painful and outdated.
- Fact: Modern rabies vaccines are much less painful than older versions and are administered intramuscularly. PEP is highly effective when administered promptly.
The Importance of Wound Care
Proper wound care is crucial in addition to PEP. This includes:
- Washing the wound thoroughly with soap and water for at least 10-15 minutes.
- Applying an antiseptic solution, such as iodine or alcohol.
- Seeking immediate medical attention to assess the need for further treatment, such as antibiotics or tetanus prophylaxis.
Finding a Rabies Vaccination Provider
Contact your local health department or primary care physician to locate a rabies vaccination provider near you. Hospitals and urgent care centers can also administer PEP. Time is of the essence, so don’t delay seeking treatment.
Prevention is Key
Preventing rabies exposure is the best defense. This includes:
- Vaccinating your pets regularly.
- Avoiding contact with wild animals.
- Supervising children when they are outdoors to prevent them from approaching unfamiliar animals.
- Reporting any stray or aggressive animals to animal control.
How Many Rabies Shots Do You Need If Bitten? – A Final Word
Understanding the importance of prompt treatment after a potential rabies exposure is critical. Familiarize yourself with the PEP regimen and seek immediate medical attention if you’ve been bitten or scratched by a potentially rabid animal.
FAQs
How long can you wait to get a rabies shot after being bitten?
The sooner you start post-exposure prophylaxis (PEP), the better. Ideally, PEP should be initiated as soon as possible after exposure, preferably within 24-48 hours. Delaying treatment increases the risk of the virus reaching the brain, making the infection more difficult to control. However, PEP can still be effective even if started later, though its effectiveness may be reduced.
What are the side effects of rabies shots?
Modern rabies vaccines are generally safe and well-tolerated. Common side effects include pain, redness, swelling, or itching at the injection site. Some people may also experience mild systemic symptoms like headache, muscle aches, fatigue, or nausea. Serious side effects are rare.
What happens if you don’t get rabies shots after being bitten?
If you are exposed to rabies and do not receive PEP, the consequences can be fatal. Rabies is almost always fatal once symptoms develop. The virus attacks the brain and nervous system, leading to neurological dysfunction, paralysis, coma, and ultimately death.
Is rabies treatment more painful now than in the past?
No, modern rabies vaccines are significantly less painful than older vaccines. Previous rabies vaccines were administered as a series of painful injections into the abdomen. Current vaccines are given intramuscularly, and the injections are generally well-tolerated.
Can you be tested for rabies before getting the shots?
There is no readily available or reliable test to determine if a person has been infected with rabies before symptoms appear. The decision to administer PEP is based on the risk of exposure, not on a diagnostic test. If the animal is available, it can be tested for rabies. If the animal tests positive, PEP is essential. If the animal tests negative, PEP can be stopped.
What if the animal that bit me is captured and tests negative for rabies?
If the animal that bit you is captured and tests negative for rabies, your healthcare provider may discontinue PEP. This eliminates the need for further vaccinations, provided the test results are reliable and the animal shows no signs of rabies.
Can you get rabies from a scratch?
Yes, rabies can be transmitted through a scratch if the animal’s saliva comes into contact with the wound. The virus is present in the saliva of infected animals, and any break in the skin can provide an entry point. Therefore, even a scratch should be treated as a potential exposure and evaluated by a healthcare professional.
Are rabies shots safe during pregnancy?
Yes, rabies shots are considered safe during pregnancy. The benefits of preventing rabies outweigh the potential risks of vaccination. If a pregnant woman is exposed to rabies, she should receive PEP without delay.
How effective are rabies shots?
Post-exposure prophylaxis (PEP) is highly effective in preventing rabies if administered promptly and correctly. PEP has a near 100% success rate when given before the onset of symptoms. The combination of RIG and the rabies vaccine provides both immediate and long-term protection.
Do I need a booster shot if I received pre-exposure rabies vaccination years ago?
People who received pre-exposure rabies vaccination (PrEP) may need a booster shot if they are exposed to rabies again. However, instead of the full four-dose series, they will usually only need two booster doses given on days 0 and 3. Your healthcare provider will determine the need for a booster based on your individual circumstances and exposure history.
Is it safe to drink alcohol after getting rabies shots?
While there isn’t specific evidence that alcohol directly interferes with the rabies vaccine, it is generally recommended to avoid excessive alcohol consumption during the vaccination series. Alcohol can suppress the immune system and may potentially affect the body’s response to the vaccine. It’s best to consult with your healthcare provider for personalized advice.
How much does rabies post-exposure treatment (PEP) cost?
The cost of rabies PEP can vary significantly depending on several factors, including the type of vaccine used, the number of doses required, the cost of rabies immunoglobulin (RIG), and the healthcare provider’s fees. It can range from several hundred to several thousand dollars. Health insurance may cover some or all of the costs. Contact your insurance provider for details on coverage.
