Why rabies vaccines can fail: Former Army Doctor warns of critical gaps in treatment

Kolhapur: Rabies is among the deadliest infectious diseases, yet it is also one of the most preventable when timely and correct post-exposure treatment is followed. A former Army doctor has explained why rabies vaccination, despite being highly effective, can sometimes fail and highlighted the critical steps that must be taken to prevent avoidable deaths.

The explanation follows a reported case from Maharashtra's Kolhapur, where a 21-year-old woman died of rabies despite receiving a full five-dose anti-rabies vaccine schedule along with rabies immunoglobulin (RIG) after a dog bite.

In a recent post on X, former Army doctor DR AK explained that anti-rabies treatment is a carefully coordinated process involving immediate wound care, proper administration of RIG, correct vaccine technique, and maintaining vaccine quality. Mistakes at any stage can reduce the chances of preventing the disease.

Key Reasons Why Anti-Rabies Treatment Can Fail

1. Improper stitching of bite wounds

The doctor warned that stitching a dog bite wound too early can increase the risk of trapping the virus inside the tissues. Deep bite wounds should generally be avoided from being stitched immediately, and if closure is required, proper administration of rabies immunoglobulin should be ensured first.

2. Cold-chain failure affecting vaccine potency

Rabies vaccines are temperature-sensitive biological products. Exposure to excessive heat or freezing conditions can reduce their effectiveness.

Healthcare facilities must maintain strict cold-chain systems, regularly monitor storage temperatures, and ensure that vaccines are properly stored before administration.

3. Improper administration of Rabies Immunoglobulin (RIG)

RIG plays a crucial role in severe animal bite exposures, especially during the early phase after infection. The doctor explained that RIG should be infiltrated directly into and around the bite wound rather than being given only at a distant site, as the virus is initially present at the wound area.

4. Inadequate Wound Cleaning

The bite area should be washed immediately with soap and running water for at least 15 minutes. This simple action can remove a large amount of virus from the wound and significantly reduce the risk of infection.

Most people and even some hospitals skip this and lose a crucial opportunity to reduce viral exposure.

5. Vaccine Must Be Given Correctly

The rabies vaccine must be administered correctly to generate an effective immune response. In adults, it is generally given in the upper arm (deltoid region).

Injection at inappropriate sites, such as the buttocks, may result in inadequate protection and should be avoided. The doctor said, “Wrong place = poor protection.”

6. Severe bites with high viral exposure

Some bites carry a higher risk because of the amount of virus introduced into the body. The doctor noted that cases where an infected dog bites multiple people in a short period require especially careful assessment and treatment.

7. Correct Timing of All Vaccine Doses Matters

Patients must complete the recommended vaccination schedule on time. Missing doses or significant delays can reduce the effectiveness of protection.

8. Overlooking small scratches or puncture wounds

Minor injuries are often ignored, but even tiny breaks in the skin can allow the rabies virus to enter the body. The doctor stressed the importance of a complete examination after a dog bite, including checking for hidden wounds and ensuring every injury is properly cleaned and managed.

9. Reduced immune response in some individuals

In rare cases, certain individuals may not develop an adequate antibody response after vaccination due to underlying immune-related issues.

10. Vaccine quality and storage issues

The doctor also raised concerns about vaccine quality, including expired, improperly stored, or sub-potent vaccine batches. Proper training of healthcare workers, real-time monitoring of vaccine stocks, and accountability in storage practices can help reduce such risks.

The doctor stressed that rabies is almost entirely preventable when post-exposure measures are followed correctly.

“Wash the wound with soap and water for 15 minutes. Ensure RIG is properly administered when indicated. Complete all vaccine doses on time. Never ignore even a small dog bite,” the doctor added.
