Does a person need a rabies vaccine after being scratched and bleeding from a vaccinated cat?

Being scratched by a cat is a very common occurrence in daily life. Many people are uncertain whether a cat scratch requires vaccination, nor do they know how to properly manage such injuries. So, if you are scratched and bleed from a cat that has been vaccinated, do you still need to receive injections? Below, we address this question.

Do you need injections after being scratched and bleeding from a vaccinated cat?

Generally speaking, yes—you still require post-exposure prophylaxis (PEP), including rabies vaccination, even if the cat has been vaccinated. Vaccination of the cat only protects the animal itself against rabies; it does not guarantee that the cat is free of rabies virus or other pathogens. Moreover, rabies is virtually 100% fatal once clinical symptoms develop; therefore, prompt medical intervention—including timely vaccination—is essential. However, note the following immediate first-aid steps: First, thoroughly wash the wound with soap and running water for at least 20 minutes. Then rinse thoroughly with clean water. Next, disinfect the wound with iodine tincture, followed by wiping off the iodine with alcohol. Crucially, avoid further contact between the exposed wound and the cat. Immediately seek medical attention at a hospital. In addition to receiving the rabies vaccine, you may also require tetanus immune globulin (TIG), depending on your vaccination history and wound severity.

Knowledge Expansion: Symptoms of Rabies

1. Neuropsychiatric abnormalities

After the rabies virus invades the central nervous system, it affects not only respiration but also speech and behavior. Patients may exhibit incoherent speech, extreme sensitivity to any external stimuli, and aggressive behavior toward others. Additional manifestations include psychosis, visual hallucinations, and auditory hallucinations.

2. Pharyngeal muscle spasms

Viral invasion of the nervous system leads to pharyngeal muscle spasms. These spasms may extend to respiratory muscles, resulting in dyspnea. Due to excessive sympathetic nervous system activation, patients may experience profuse sweating and hypersalivation. Swallowing fluids or food becomes extremely difficult, leading to dehydration and high fever.

3. Systemic symptoms

Patients with rabies may also present early nonspecific systemic symptoms, including low-grade fever, fatigue, headache, nausea, and vomiting. As the disease progresses, more severe manifestations emerge—such as high fever, hypersalivation, diaphoresis, tachycardia, and hypertension.

The above outlines whether injections are necessary after being scratched and bleeding from a vaccinated cat. We hope this information proves helpful to you.
