Anti-Rabies Vaccine: The anti-rabies vaccine is administered following a dog bite; however, people often either forget to take all the required doses or fail to take them at the correct intervals, resulting in a gap in the vaccination schedule. Consequently, in many cases, this leads to dire consequences. The patient contracts rabies, and—given that this disease is 100% fatal—the ensuing death is extremely agonizing. Nevertheless, if people possess accurate information, the likelihood of making such errors is significantly reduced, and this highly dangerous disease can be effectively prevented.

The guidelines issued by the National Rabies Control Program (NRCP) state that the sooner the Anti-Rabies Vaccine (ARV) is administered after a dog bite, the better. Any delay in doing so increases the risk of contracting rabies. Vaccination should ideally commence on the very day the dog bite occurs. While rabies is 100% fatal, it is a completely preventable disease.
The guidelines recommend that immediately after a dog bite, the wound should be thoroughly cleaned (Wound Washing) using soap and running water. After washing the wound with soap and running water for 15 minutes, an antiseptic cream may be applied; the next immediate step should be to proceed to a vaccination center to receive the vaccine as quickly as possible.
Most importantly—whether the individuals are pregnant women, children, or people with compromised immunity battling other illnesses—it is mandatory for everyone to complete the full course of vaccination. Let us explore the answers to some key questions regarding the vaccine below:
Within how many hours of a dog bite should the vaccine be administered?
If bitten by a dog, it is imperative to get vaccinated immediately. The sooner the anti-rabies vaccine is administered, the stronger the protection against the disease. Even if there is an unavoidable delay for any reason, it remains crucial to receive the vaccine within 24 hours to ensure protection against rabies.
How many doses of the vaccine are required?
If a person has been bitten by a dog, a course of 4 to 5 doses of the anti-rabies vaccine is administered. However, if there is only a minor scratch or marks from a dog's claws, a doctor may increase the dosage to three shots. Nevertheless, one should not decide independently how many doses of the vaccine are required; it is imperative to visit a medical professional to receive the vaccine following a dog bite.
**Where is this vaccine administered?**
According to the National Rabies Control Program, the anti-rabies vaccine is administered in the arm. This vaccine can be given via two routes: Intradermal (ID) and Intramuscular (IM). However, in India, the preferred and most widely used method—being both cost-effective and efficient—is the Intradermal route.
**When is this vaccine administered?**
Typically, four doses of the Intradermal vaccine are administered, involving a total of eight injections. These doses are given on Day 0, Day 3, Day 7, and Day 28. In contrast, for the Intramuscular (IM) route, an additional dose is administered on Day 14 (in addition to the aforementioned days), bringing the total number of doses to five.
**Does taking the vaccine guarantee protection against rabies?**
According to the Union Ministry of Health—and as affirmed by medical professionals—regardless of the severity of the dog bite, if a patient receives the rabies vaccine at the prescribed times and strictly adheres to the complete vaccination schedule, they will not contract rabies and are afforded 100% protection.
**Are there adverse consequences to skipping a vaccine dose or creating a gap in the schedule?**
It is essential to complete the full course of the vaccination. It is crucial to receive the vaccine without any gaps or interruptions to effectively eliminate the risk of rabies. Failure to receive all the required doses may leave one vulnerable to the risk of contracting rabies.
